Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Recently LHCb reported the discovery of four extremely narrow excited $Ω_b$ baryons decaying into $Ξ_b^0 K^-$. We interpret these baryons as bound states of a $b$-quark and a $P$-wave $ss$-diquark. For such a system there are exactly five possible combinations of spin and orbital angular momentum. We predict two of spin 1/2, two of spin 3/2, and one of spin 5/2, all with negative parity. We favor identifying the observed states as those those with spins 1/2 and 3/2, and give a range of predicted masses for the one with spin 5/2. We update earlier predictions for these states based on the five narrow excited $Ω_c$ states reported by LHCb. An alternative picture of the states in which one of $J=1/2$ is extremely wide and hence not seen by LHCb is discussed.

description: In a very recent work it was shown how to systematically generate particle-like scattering states in wave transport through complex scattering systems [PRL 106, 120602 (2011)]. These beam-like states have a number of interesting properties like a highly collimated wave function and deterministic values of transmission through a system. Such properties are of importance for saving power in the signal transmission, for security issues (to avoid eavesdropping), for improving the signal quality as well as for the focusing of waves on a small spot. In view of such a broad range of possible applications, this diploma thesis will cover the theoretical side of a microwave realization of such particle like states in collaboration with the University of Nice, where the effect of all the imperfections, that an experiment typically comes along with, will be investigated and quantified. The second part of this diploma thesis will deal with the recently introduced so-called Constant-intensity waves [Nature Communications 6, 7257 (2015)]. This new type of wave has constant intensity in the presence of linear as well as nonlinear inhomogeneous media with gain and loss. The characterization of these waves as well as new possible applications will be part of this thesis.
title: Preparatory experiments for a cosmic Bell test and satellite-based quantum communication
Creators: name: Bricher, David
Publisher: name: TU Wien
Year: 2016
Subjects: subject: Physics

description: This thesis describes those preparatory experiments, that are essiential for the realization of two planned quantum free-space projects. The Quantum Experiments at Space Scale (QUESS) project pursues the aim to enable an unconditional secure quantum key exchange between a satellite and different optical ground stations. Therefore, a satellite mock-up system has been developed, that is used to test the receiving modules of the ground stations located in Tenerife and Graz. Within the second experiment described, a cosmic Bell test is planned to be carried out in order to close the "freedom-of-choice" loophole. The realization and preparation of the used polarization analyzation modules are treated in detail. Additionally, different sources of random numbers are analyzed on their influence on the violation of the Bell inequality.

description: We report redshift measurements for 12 BL Lacertae objects from a program aimed at obtaining high signal to noise (up to ~ 500) optical spectroscopy of a mixed sample of objects. The new observations, gathered with the 8 m ESO Very Large Telescope, allowed us to detect weak spectral features down to a line equivalent width as small as ~ 1 Angstrom. The new redshifts fall in the 0.2-1.3 interval. For nine objects we observe emission lines from the active nucleus. In the remaining three cases absorption lines from the host galaxy are found. For two objects we also detect absorption lines from intervening systems.

Ergodic Concepts for a Self-Organizing Trivalent Spin Network: A Path to $(2+1)$-dimensional Black Hole Entropy
Creators: name: Dantas, Christine C.

Year: 2023
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We consider, from a dynamical systems point of view, a trivalent spin network model in Loop Quantum Gravity presenting self-organized criticality (SOC), arising from a spin propagation dynamics. We obtain a partition function for the domains of stability connecting gauge non-invariant avalanches, leading to an entropy formula for the asymptotic SOC state. The microscopic origin of this SOC entropy is therefore given by the excitation-relaxation spin dynamics in the avalanche cycle. The puncturing of TSN edges participating in the avalanche are counted in terms of an ensemble perimeter over the implicit avalanches. By identifying this perimeter with that of an isolated $(2+1)$-dim. black hole horizon, we conjecture that the SOC entropy reduces to the Bekenstein-Hawking perimeter-entropy law for the Bañados, Teitelboim, and Zanelli (BTZ) black hole, by an appropriate adjustment of a potential function based on the thermodynamical formalism of Sinai, Ruelle and Bowen.

description: Radio emission from cosmic ray air showers has the potential to become an additional, cost-effective observing technique for cosmic ray research, being largely complementary to the well-established particle detector and air fluorescence techniques. We present Monte Carlo simulatios of radio emission from extensive air showers in the scheme of coherent geosynchrotron radiation from electron-positron pairs gyrating in the earth's magnetic field. Preliminary results of our simulations are the predicted frequency, primary particle energy, shower zenith angle, shower azimuth angle and polarization dependence of the radio emission. These properties can be directly related to data measured by LOPES and other experiments.

CO adsorption on the Pt(111) surface: a comparison of a gradient corrected functional and a hybrid functional
Creators: name: Doll, K.

Year: 2004
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: The adsorption of CO on the Pt(111) surface in a root3 x root3 pattern has been studied with the gradient corrected functional of Perdew and Wang and the B3LYP hybrid functional. A slab which is periodic in two dimensions is used to model the system. The Perdew-Wang functional incorrectly gives the fcc site as the most favorable adsorption site, in accord with a set of previous studies. The B3LYP functional gives the top site as the preferred site. This confirms results from cluster studies where it was suggested that the different splitting, dependent on the functional, between highest occupied and lowest unoccupied molecular orbital, could be the reason for this change of the adsorption site. This is supported by an analysis based on the projected density of states and the Mulliken population.

description: Consider an input-output system where the output is the tracking error given some desired reference signal. It is natural to consider under what conditions the problem has an exact solution, that is, the tracking error is exactly the zero function. If the system has a well defined relative degree and the zero function is in the range of the input-output map, then it is well known that the system is locally left invertible, and thus, the problem has a unique exact solution. A system will fail to have relative degree when more than one exact solution exists. The general goal of this paper is to describe a decomposition of an input-output system having a Chen-Fliess series representation into a parallel product of subsystems in order to identify possible solutions to the problem of zeroing the output. For computational purposes, the focus is on systems whose generating series are polynomials. It is shown that the shuffle algebra on the set of generating polynomials is a unique factorization domain so that any polynomial can be uniquely factored modulo a permutation into its irreducible elements for the purpose of identifying the subsystems in a parallel product decomposition. This is achieved using the fact that this shuffle algebra is isomorphic to the symmetric algebra over the vector space spanned by Lyndon words. A specific algorithm for factoring generating polynomials into its irreducible factors is presented based on the Chen-Fox-Lyndon factorization of words.

title: Cycles of Engagement: how public sector clients and their consultants engage on IT projects
Creators: name: Hartnett, Elizabeth Jean
Publisher: name: The Open University
Year: 2011

description: The aim of this thesis is to investigate how public sector clients engage with external clients on information technology projects. It does so by gathering documentary and interview information from clients and consultants on five public sector IT projects. The data were analysed using thematic and template analysis, resulting in a potential model of how project participants build engaged relationships. Little research has investigated the client-consultant relationship on IT projects and a literature review revealed little theoretical basis to model engagement between participants arriving new to a project with no pre-existing relationships. By drawing on related literature and qualitative research data, the thesis develops a conceptual model of engagement with components that explain engaged relationships in terms of interaction between conditions and behaviours. Emerging behaviours are identified as sharing, sense making and adapting and these behaviours arise from conditions of environment, participants and expertise. Sharing and sense making behaviours reinforce each other, and lead to adapting, and a consequence of adapting is the potential to change conditions. Adapting conditions alters behaviours, which in turn can alter conditions, thus implying that once started, engagement is a dynamic self-replicating phenomenon with cycles that a manager or consultant can identify and alter for the benefit of the project. The research contributes to theory by offering an understanding of the phenomenon of engagement between participants on projects, demonstrating the self-reinforcing role of conditions and behaviours and adding to theories of client-consultant relationships. The research findings offer consultants and their clients a means to identify how they can deliberately alter engagement to improve a project’s process.

description: We present high spatial resolution (2.3"x1.9" or 43 pc x 36 pc at D = 3.9 Mpc) 100 GHz millimeter-wave continuum emission observations with the Nobeyama Millimeter Array toward an expanding molecular superbubble in the central region of M82. The 100 GHz continuum image, which is dominated by free-free emission, revealed that the four strongest peaks are concentrated at the inner edge of the superbubble along the galactic disk. The production rates of Lyman continuum photons calculated from 100 GHz continuum flux at these peaks are an order of magnitude higher than those from the most massive star forming regions in our Galaxy. At these regions, high velocity ionized gas (traced by H41a and [Ne II]) can be seen, and H2O and OH masers are also concentrated. The center of the superbubble, on the other hand, is weak in molecular and free-free emissions and strong in diffuse hard X-ray emission. These observations suggest that a strong starburst produced energetic explosions and resultant plasma and superbubble expansions, and induced the present starburst regions traced by our 100 GHz continuum observations at the inner edge of the molecular superbubble. These results, therefore, provide the first clear evidence of self-induced starburst in external galaxies. Starburst at the center of the superbubble, on the other hand, begins to cease because of a lack of molecular gas. This kind of intense starburst seems to have occurred several times within 10^6-10^7 years in the central region of M82.

description: Active learning parallelization is widely used, but typically relies on fixing the batch size throughout experimentation. This fixed approach is inefficient because of a dynamic trade-off between cost and speed -- larger batches are more costly, smaller batches lead to slower wall-clock run-times -- and the trade-off may change over the run (larger batches are often preferable earlier). To address this trade-off, we propose a novel Probabilistic Numerics framework that adaptively changes batch sizes. By framing batch selection as a quadrature task, our integration-error-aware algorithm facilitates the automatic tuning of batch sizes to meet predefined quadrature precision objectives, akin to how typical optimizers terminate based on convergence thresholds. This approach obviates the necessity for exhaustive searches across all potential batch sizes. We also extend this to scenarios with constrained active learning and constrained optimization, interpreting constraint violations as reductions in the precision requirement, to subsequently adapt batch construction. Through extensive experiments, we demonstrate that our approach significantly enhances learning efficiency and flexibility in diverse Bayesian batch active learning and Bayesian optimization applications.

description: Les bulbilles sont des tubercules aériens qui ont contribué naturellement à la dispersion des espèces ayant l'aptitude à en produire, mais souvent de manière sporadique. L'intérêt porté à la maîtrise de la production des bulbilles vient du fait qu'elle peut constituer pour certaines espèces, une voie alternative originale à la production de semences d'igname. Les travaux rapportés dans ce papier reposent sur les observations conduites sur les facteurs de promotion de la bulbification chez D. alata cv Belep. Depuis 2 ans nous obtenons une production régulière de bulbilles sur cette variété à partir de tubercules entiers ou fragmentés. Le nombre moyen total de bulbilles récoltées par plante se situe entre 20 et 30 et le nombre moyen de bulbilles utilisables comme semences pour la culture suivante est compris entre 6 et 10. La formation des bulbilles (phénomène terminal du cycle) ne semble pas être en compétition avec la production des tubercules car les rendements en tubercules observés donnent des valeurs comprises entre 2.3 et 3.8 kg par plante selon le poids des tubercules utilisés comme matériel de plantation.

description: This paper aims to develop an inter-disciplinary conceptual framework through review of literature on the relationship among corruption, corruption in public procurement (CiPP), and effects of CiPP on the tax morale (TM). As proposed by Bernheim and Whinston (1986), the ‘Agency theory’ (AT) is applied to view and explain the occurrence of multiple agency problem(s) in PP arising due to high stakes of divergent stakeholders such as: (1) electorate (the public), (2) political elite (elected representative(s), chief executive(s), and cabinet minister(s) etc.), (3) influence group(s), and (4) PP professionals (PPP). Potential of PP to act as a potent tool of public-policy-implementation is suggested by scholars if transparency in PP is ensured. Effect of inefficiencies in governance on the taxpayers’ TM is highlighted in the literature however, CiPP is presented as an inefficiency in judicious utilization of public money. Corruption-free PP will not only help the governments to ‘do more with less’ by eliminating inefficiencies (CiPP) but establish the moral authority of governments (especially in developing countries) to raise TM of taxpayers for raising tax collection and channelizing taxpayers’ money for improving socioeconomic indicators in the developing economies. Two main types of corruption (grand, and legislative) are in the scholastic focus from different subjects however, petty corruption (here CiPP) is not much focused in the studies conducted so far.
A theoretical model for power generation via liquid crystal elastomers

Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: Motivated by the need for new materials and green energy production and conversion processes, a class of mathematical models for liquid crystal elastomers integrated within a theoretical charge pump electrical circuit is considered. The charge pump harnesses the chemical and mechanical properties of liquid crystal elastomers transitioning from the nematic to isotropic phase when illuminated or heated to generate higher voltage from a lower voltage supplied by a battery. For the material constitutive model, purely elastic and neoclassical-type strain energy densities applicable to a wide range of monodomain nematic elastomers are combined, while elastic and photo-thermal responses are decoupled to make the investigation analytically tractable. By varying the model parameters of the elastic and neoclassical terms, it is found that liquid crystal elastomers are more effective than rubber when used as dielectric material within a charge pump capacitor.
Middle school students’ generalizations about properties of geometric transformations in a dynamic geometry environment

Year: 2020

description: Making generalization is fundamental to mathematics and a crucial component of mathematical thinking. To help learners become more proficient at constructing mathematical generalizations, it is vital to better understand the forms that the constructive process might take in various mathematical contexts. The study reported here aimed to offer an empirically grounded theory of forms of generalization middle students made as they engaged in explorations regarding geometric transformations within a dynamic geometry environment. Based on their sources, participants’ statements about properties of geometric transformations were categorized into four types: context-bounded properties, perception-based generalizations, process-based generalizations, and theory-based generalizations. Although these forms of generalizations are different in their construction process, with appropriate pedagogical support generalizations of the same type and different types of generalizations can build on each other. DGS mediated the construction of these forms of generalizations based on how learners used it.

description: It was shown recently that in four dimensions scalar sources with fixed proper acceleration minimally coupled to a massless Klein-Gordon field lead to the same responses when they are (i) uniformly accelerated in Minkowski spacetime (in the inertial vacuum) and (ii) static in the Schwarzschild spacetime (in the Unruh vacuum). Here we show that this equivalence is broken if the spacetime dimension is more than four.

description: The rising demand for high quality display has ensued active research in high dynamic range (HDR) imaging, which has the potential to replace the standard dynamic range imaging. This is due to HDR's features like accurate reproducibility of a scene with its entire spectrum of visible lighting and color depth. But this capability comes with expensive capture, display, storage and distribution resource requirements. Also, display of HDR images/video content on an ordinary display device with limited dynamic range requires some form of adaptation. Many adaptation algorithms, widely known as tone mapping operators, have been studied and proposed in the last few decades. In this state of the art report, we present a comprehensive survey of 50+ tone mapping algorithms that have been implemented on hardware for acceleration and real-time performance. These algorithms have been adapted or redesigned to make them hardware-friendly. All real-time application poses strict timing constraints which requires time exact processing of the algorithm. This design challenge require novel solution, and in this report we focus on these issues. In this we survey will discuss those tonemap algorithms which have been implemented on GPU [1-10], FPGA [11-41], and ASIC [42-53] in terms of their hardware specifications and performance. Output image quality is an important metric for tonemap algorithms. From our literature survey we found that, various objective quality metrics have been used to demonstrate the functionality of adapting the algorithm on hardware platform. We have compiled and studied all the metrics used in this survey [54-67]. Finally, in this report we demonstrate the link between hardware cost and image quality thereby illustrating the underlying trade-off which will be useful for the research community.

description: O presente trabalho tem por objetivo analisar a dinâmica espacial recente da produção agropecuária em Minas Gerais, mais especificamente, do Produto Interno Bruto Agropecuário em 1996 e 2006. Primeiramente, é feita uma caracterização geral da produção agropecuária de Minas Gerais, incluindo a distribuição do PIB agropecuário de Minas Gerais em nível municipal. Em seguida, aborda-se a relação entre a participação relativa dos municípios e seu nível de especialização na produção agropecuária. Ademais, buscam-se identificar padrões de associação espacial e a formação de clusters com municípios de maior participação no PIB agropecuário de Minas Gerais no período. Por fim, são apontadas algumas diretrizes de políticas públicas voltadas para o aumento da produção agropecuária e consolidação dos clusters de municípios identificados......The present paper aims to analyze the recent spatial dynamics of the agricultural farming and cattle raising sector in the State of Minas Gerais. The focus is on the sector GDP in 1996 and 2006. First, we develop a general characterization of the agricultural farming and cattle raising production in Minas Gerais, including the sector GDP distribution among municipalities. Next, we analyze the relation between the relative municipality’s participation and the specialization level in the sector production. Furthermore, we try to identify patterns of spatial association and cluster formation for the largest municipalities in terms of participation in the sector GDP. Finally, we suggest some public policy recommendation to achieve higher agricultural farming and cattle raising output and to consolidate the identified municipality’s clusters.

description: I present preliminary results on the search for $h_c$ in its $η_cγ$ and $J/ψπ^0$ decay modes. We observe an excess of η_cγ$ events near 3526 MeV that has a probability ${\cal P} \sim 0.001$ to arise from background fluctations. The resonance parameters are $M=3525.8 \pm 0.2 \pm 0.2 $MeV, $Γ\leq$ 1 MeV, and $10.6\pm 3.7\pm3.4(br) < Γ_{\bar{p}p}B_{η_cγ} < 12.8\pm 4.8\pm4.5(br) $eV. We find no event excess within the search region in the $J/ψπ^0$ mode.

title: Participative Approaches to Hedgerow Conservation
Creators: name: Oreszczyn, Susan
Publisher: name: The Open University
Year: 1999

description: This thesis demonstrates how systems ideas and grounded theory have been applied to provide a broader approach to researching hedgerows in England, drawing on the idea that holistic thinking brings together different people’s relationships with hedgerows and with each other concerning hedgerows. The cultural dimensions of hedgerows and their implications for future hedged landscapes were investigated through the collection and exploration of different groups perspectives - public, farmers and experts - in England and Canada, using a diversity of primary and secondary data sources. English hedgerows were important to all groups. Everyone liked hedged landscapes for aesthetic, visual and wildlife reasons. They were important for the way they break up the landscape; provide signs of the changing seasons; their sense of mystery and intimacy; their connections with the past and childhood memories. They are also seen as part of England’s history and national identity. Such cultural identity was absent in the Canadian data. However, some groups also held a rational or objective view which was dominant over this subjective or emotional view and which affects where they draw the boundaries to their systems of interest. Farmers were most concerned with their farms (and the hedgerows they owned) as a business, while experts dealt mainly with the ecological aspects of hedgerows. There was found to be little awareness of others groups views with different groups seeing the same action in very different ways. Even where there was contact between farmers and experts, there could be a lack of trust. Finally, it is noted that policy and practice towards hedgerows have ignored many of these relationships and that the approach used here offers opportunities to examine the different systems of interest.

Metal rich stars in omega Cen: preliminary FLAMES GTO results

description: I present preliminary results for a sample of ~700 red giants in omega Cen, observed during the Ital-FLAMES Consortium GTO time in May 2003, for the Bologna Project on omega Cen. Preliminary Fe and Ca abundances confirm previous results: while the metal-poor and intermediate populations show a normal halo alpha-enhancement of [alpha/Fe]=$+0.3, the most metal-rich stars show a significantly lower [alpha/Fe]=+0.1. If the metal-rich stars have evolved within the cluster in a process of self-enrichment, the only way to lower their alpha-enhancement would be SNe type Ia intervention.

description: Quantum annealing aims at solving optimization problems efficiently by preparing the ground state of an Ising spin-Hamiltonian quantum mechanically. A prerequisite of building a quantum annealer is the implementation of programmable long-range two-, three- or multi-spin Ising interactions. We discuss an architecture, where the required spin interactions are implemented via two-port, or in general multi-port quantum Ising wires connecting the spins of interest. This quantum annealing architecture of spins connected by Ising quantum wires can be realized by exploiting the three dimensional (3D) character of atomic platforms, including atoms in optical lattices and Rydberg tweezer arrays. The realization only requires engineering on-site terms and two-body interactions between nearest neighboring qubits. The locally coupled spin model on a 3D cubic lattice is sufficient to effectively produce arbitrary all-to-all coupled Ising Hamiltonians. We illustrate the approach for few spin devices solving Max-Cut and prime factorization problems, and discuss the potential scaling to large atom based systems.

Stabilization of three-dimensional matter-waves solitons in an optical lattice

description: We propose an experimentally relevant scheme to create stable solitons in a three-dimensional Bose-Einstein condensate confined by a one-dimensional optical lattice, using temporal modulation of the scattering length (through ac magnetic field tuned close to the Feshbach resonance). Another physical interpretation is a possibility to create stable 3D "light bullets" in an optical medium with a longitudinal alternating self-focusing/defocusing structure, and periodic modulation of the refractive index in a transverse direction. We develop a variational approximation to identify a stability region in the parametric space, and verify the existence of stable breathing solitons in direct simulations. Both methods reveal that stable solitons may be supported if the average value of the nonlinear coefficient (whose sign corresponds to attraction between atoms) and the lattice's strength exceed well-defined minimum values. Stable localized patterns may feature a multi-cell structure.

title: Entanglement entropy of a compact region in a 2D-dilaton gravity theory
Creators: name: Kapetanoski, Ognen
Publisher: name: TU Wien
Year: 2016
Subjects: subject: holographic entanglement entropy
subject: numerical relativity
subject: heavy ion collisions

description: The two-point function and the entanglement entropy can be seen as quan-tities to describe properties of the quark-gluon plasma. For this an anisotropicc 5-dimensional system is considered. A homogeneous anisotropic but O (2) symmetric solution to the 5-dimensional vacuum Einstein equations is equivalent to a homogeneous and isotropic solution to the Einstein equations including a scalar field. The corresponding 5-dimensional Einstein-Hilbert action without scalar field can be dimensionally reduced to a 2-dimensional dilaton gravity action with two scalar fields. The same 2-dimensional dilaton gravity action arises from reducing isotropic Ein- stein gravity with a minimally coupled massless scalar field. Therefore, the 2-dimensional dilaton gravity is equivalent to the 5-dimensional anisotropic system with matter and the 5-dimensional isotropic system with a scalar field. In this thesis the two-point function of operators of large conformal weight and the holographic entanglement entropy for a spherical region in a 2-dimensional dilaton gravity theory are calculated numerically using the Anti-de Sitter/conformal field theory correspondence. The two-point function, which is computed in the geodesic approximation, amounts to a geodesic-s length in the gravity theory. Similarly the calculation of the entanglement entropy reduces to finding geodesics in an auxiliary spacetime. To obtain the geometry the Einstein equations need to be solved numerically. The Einstein equations of the 2-dimensional dilaton gravity theory are mapped to the vacuum Einstein equations for an anisotropic geometry. The numerical calculation of geodesics is performed using a Mathematica package, which calculates the geodesics with a relaxation method. The results for the entanglement entropy and two-point function vary strongly, depending on the chosen boundary region.
Mother-child interactions while sharing print and electronic versions of books
Creators: name: Kim, Ji Eun
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to compare (1) mother-child interactions in three different contexts: sharing a picture book in traditional paper format, sharing an electronic book in CD-ROM format and sharing an electronic book in video-clip format; (2) a mother’s interactions with her 7- and 3-year-old child; and (3) how children’s initiations differ according to age. Two boys and their mother from a middle class Korean family that recently immigrated to Canada were involved in this study. The texts for shared reading activities were provided in Korean. Four session-observations of each activity were videotaped, with a one-week interval, between sessions. The videotapes were transcribed and analyzed based on verbal event categories that emerged from the data and that were informed by the literature on shared book reading. The conversations between the mother and the child during shared reading were examined to find any predominant characteristics in the content of their talk. Findings of the study include the following: (1) there were some differences in mother-child interactions across the three contexts and these seemed to be related to different formats and features of the books, (2) mother-child interactions during the shared reading differed according to the children’s ages, and (3) the children exhibited different initiations during the shared reading according to their ages. The findings of this study suggest that different factors, such as medium of the text, the age of the children, and the children’s sociocultural experiences may be related to mother-child interactions during shared reading and may influence children’s home literacy practices. This study provides insight of the potential differences in mother-child interactions during shared reading, depending on the medium and the children’s ages.

description: Investigations of the mass and decays of the exotic hybrid are reviewed, including calculation of the pion1 to eta pion, eta-prime pion decay widths within the QCD sum rules technique. In this calculation, the recently-proposed eta, eta-prime quark mixing scheme is employed. The results indicate that the decay width Gamma(pion1 to eta pion) around 250 MeV is large compared with the decay width Gamma(pion1 to eta-prime pion) around 20 MeV. Inspired by these results, some phenomenological approaches are suggested to gain an understanding of the underlying mechanism of eta pion and eta-prime pion hybrid decays.
