Cash crop adoption by peasant households : Analysis from the middle mountains of Nepal
Creators: name: Srivastava, Lorie
Publisher: name: University of British Columbia
Year: 2009

description: Peasant households in the Middle Mountains of Nepal are faced with a myriad of problems and challenges as they attempt to improve their living conditions. Vegetable cash crop production is regarded as a possible solution to alleviating rural poverty by many households and policymakers. This study deals with the case of vegetable cash crop adoption by peasant households in a peri-urban area near Kathmandu. The two objectives of this study are to identify the determinants of vegetable cash crop adoption by peasant households, and to exarnine the implications of this adoption. This research is based on a detailed household-level survey of peasants in the Jhikhu Khola Watershed, located about 40 km east of Kathmandu. The sample is divided into households that produce vegetable cash crops, and those that do not. A dichotomous logistic model is used to determine the significant factors for the adoption of vegetable cash crops. For the second objective, the survey data is analysed to understand the implications of vegetable cash crop adoption. The effects of adoption are assessed by comparing two vegetable cash crops, potato and tomato, with two staple food crops, maize and rice. The results of the adoption/non-adoption logistic model indicate that access to irrigation water has the greatest impact on growing vegetable cash crops. There is a positive relationship between access to irrigation water and adoption of vegetable cash crops by the surveyed households. The level of formal education attained by the male household head also increases adoption rates. Difficulty with inorganic commercial fertilisers and predominantly red soils both have a negative impact on the choice to produce vegetable cash crops. An examination of the implications of cash crop adoption reveals some interesting results. Although tomatoes are the most profitable crop, many households incurred losses by cultivating potatoes due to changes in the operational environment. Households that adopt cash crops have higher returns from maize than households that choose not to adopt cash crops. Finally, in terms of food security, cash crops do not appear to adversely affect a household's staple food production.

description: This paper deals with stability of discrete-time switched linear systems whose all subsystems are unstable. We present sufficient conditions on the subsystems matrices such that a switched system is globally exponentially stable under a set of purely time-dependent switching signals that are allowed to activate all subsystems. The main apparatuses for our analysis are (matrix) commutation relations between certain products of the subsystems matrices and graph-theoretic arguments. We present a numerical experiment to demonstrate our results.

description: We present measurements of the clustering properties of galaxies in the field of redshift range $0.5 \lesssim z \lesssim 1.5$ Ultra Steep Spectrum (USS) radio sources selected from Sydney University Molonglo Sky Survey and NRAO VLA Sky Survey. Galaxies in these USS fields were identified in deep near-IR observations, complete down to $K_s=20$, using {\tt IRIS2} instrument at the AAT telescope. We used the redshift distribution of $K_{s} < 20$ galaxies taken from Cimatti et al. (2002) to constrain the correlation length $r_0$. We find a strong correlation signal of galaxies with $K_{s} < 20$ around our USS sample. A comoving correlation length $r_{0}=14.0\pm2.8$ $h^{-1}$ Mpc and $γ=1.98\pm0.15$ are derived in a flat cosmological model Universe. We compare our findings with those obtained in a cosmological N--body simulation populated with GALFORM semi-analytic galaxies. We find that clusters of galaxies with masses in the range $M=10^{13.4-14.2}$ $h^{-1}$ M$_{\sun}$ have a cluster--galaxy cross--correlation amplitude comparable to those found between USS hosts and galaxies. These results suggest that distant radio galaxies are excellent tracers of galaxy overdensities and pinpoint the progenitors of present day rich clusters of galaxies.

description: We consider a modification of QCD in which conventional fundamental quarks are replaced by Weyl fermions in the adjoint representation of the color SU(N). In the case of two flavors the low-energy chiral Lagrangian is that of the Skyrme-Faddeev model. The latter supports topologically stable solitons with mass scaling as N^2. Topological stability is due to the existence of a nontrivial Hopf invariant in the Skyrme-Faddeev model. Our task is to identify, at the level of the fundamental theory, adjoint QCD, an underlying reason responsible for the stability of the corresponding hadrons. We argue that all "normal" mesons and baryons, with mass O(N^0), are characterized by (-1)^Q (-1)^F =1, where Q is a conserved charge corresponding to the unbroken U(1) surviving in the process of the chiral symmetry breaking (SU(2) \to U(1) for two adjoint flavors). Moreover, F is the fermion number (defined mod 2 in the case at hand). We argue that there exist exotic hadrons with mass O(N^2) and (-1)^Q (-1)^F = -1. They are in one-to-one correspondence with the Hopf Skyrmions. The transition from nonexotic to exotic hadrons is due to a shift in F, namely F \to F - {\cal H} where {\cal H} is the Hopf invariant. To detect this phenomenon we have to extend the Skyrme-Faddeev model by introducing fermions.

description: In the following paper we investigate the critical temperature $T_c$ behavior in the two-dimensional S/TI (S denotes superconductor and TI - topological insulator) junction with a proximity induced in-plane helical magnetization in the TI surface. The calculations of $T_c$ are performed using the general self-consistent approach based on the Usadel equations in Matsubara Green's functions technique. We show that the presence of the helical magnetization leads to the nonmonotonic behavior of the critical temperature as a function of the topological insulator layer thickness.

The transition from adiabatic inspiral to geodesic plunge for a compact object around a massive Kerr black hole: Generic orbits

description: The inspiral of a stellar mass compact object falling into a massive Kerr black hole can be broken into three different regimes: An adiabatic inspiral phase, where the inspiral timescale is much larger than the orbital period; a late-time radial infall, which can be approximated as a plunging geodesic; and a regime where the body transitions from the inspiral to plunge. In earlier work, Ori and Thorne have outlined a method to compute the trajectory during this transition for a compact object in a circular, equatorial orbit. We generalize this technique to include inclination and eccentricity.

description: We present an exact solution of the equations for orbit determination of a two body system in a hyperbolic or parabolic motion. In solving this problem, we extend the method employed by Asada, Akasaka and Kasai (AAK) for a binary system in an elliptic orbit. The solutions applicable to each of elliptic, hyperbolic and parabolic orbits are obtained by the new approach, and they are all expressed in an explicit form, remarkably, only in terms of elementary functions. We show also that the solutions for an open orbit are recovered by making a suitable transformation of the AAK solution for an elliptic case.

description: We present Chandra observations of two relatively high redshift FRII radio galaxies, 3C 432 and 3C 191 (z=1.785 and z=1.956 respectively), both of which show extended X-ray emission along the axis of the radio jet or lobe. This X-ray emission is most likely to be due to inverse-Compton scattering of Cosmic Microwave Background (CMB) photons. Under this assumption we estimate the minimum energy contained in the particles responsible. This can be extrapolated to determine a rough estimate of the total energy. We also present new, deep radio observations of 3C 294, which confirm some association between radio and X-ray emission along the NE-SW radio axis and also that radio emission is not detected over the rest of the extent of the diffuse X-ray emission. This, together with the offset between the peaks of the X-ray and radio emissions may indicate that the jet axis in this source is precessing.

description: We investigate theoretically the interaction of polar molecules with optical lattices and microwave fields. We demonstrate the existence of frequency windows in the optical domain where the complex internal structure of the molecule does not influence the trapping potential of the lattice. In such frequency windows the Franck-Condon factors are so small that near-resonant interaction of vibrational levels of the molecule with the lattice fields have a negligible contribution to the polarizability and light-induced decoherences are kept to a minimum. In addition, we show that microwave fields can induce a tunable dipole-dipole interaction between ground-state rotationally symmetric (J=0) molecules. A combination of a carefully chosen lattice frequency and microwave-controlled interaction between molecules will enable trapping of polar molecules in a lattice and possibly realize molecular quantum logic gates. Our results are based on ab initio relativistic electronic structure calculations of the polar KRb and RbCs molecules combined with calculations of their rovibrational motion.

description: We study the dynamics of strongly coupled nanophotonic systems with time-variable parameters. The approximate analytic solutions are obtained for a broad class of open quantum systems including a two-level fermion emitter strongly coupled to a multimode quantized electromagnetic field in a cavity with time-varying cavity resonances or the electron transition energy. The coupling of the fermion and photon subsystems to their dissipative reservoirs is included within the stochastic equation of evolution approach, which is equivalent to the Lindblad approximation in the master equation formalism. The analytic solutions for the quantum states and the observables are obtained under the approximation that the rate of parameter modulation and the amplitude of the frequency modulation are much smaller than the optical transition frequencies. At the same time, they can be arbitrary with respect to the generalized Rabi oscillations frequency which determines the coherent dynamics. Therefore, our analytic theory can be applied to an arbitrary modulation of the parameters, both slower and faster than the Rabi frequency, for complete control of the quantum state. In particular, we demonstrate protocols for switching on and off the entanglement between the fermionic and photonic degrees of freedom, swapping between the quantum states, and the decoupling of the fermionic qubit from the cavity field due to modulation-induced transparency.

description: A search for $α$ decay of naturally occurring osmium isotopes to the lowest excited levels of daughter nuclei has been performed by using an ultra-low-background Broad-Energy Germanium $γ$-detector with a volume of 112 cm$^3$ and an ultra-pure osmium sample with a mass of 118 g at the Gran Sasso National Laboratory of the INFN (Italy). The isotopic composition of the osmium sample has been measured with high precision using Negative Thermal Ionisation Mass Spectrometry. After 15851 h of data taking with the $γ$-detector no effect has been detected, and lower limits on the $α$ decays were set at level of $\lim T_{1/2}\sim 10^{15}-10^{19}$ yr. The limits for the $α$ decays of $^{184}$Os and $^{186}$Os to the first excited levels of daughter nuclei, $T_{1/2}(^{184}$Os$)\geq 6.8\times10^{15}$ yr and $T_{1/2}(^{186}$Os$)\geq3.3\times10^{17}$ yr (at 90% C.L.), exceed the present theoretical estimates of the decays half-lives. For $^{189}$Os and $^{192}$Os also decays to the ground states of the daughter nuclei were searched for due to the instability of the daughter nuclides relative to $β$ decay.

description: The kinematics of particles moving in rainbow spacetime is studied in this paper. In particular the geodesics of a massive particle in rainbow flat spacetime is obtained when the semi-classical effect of its own energy on the background is taken into account. We show that in general the trajectory of a freely falling particle remains unchanged which is still a straight line as in the flat spacetime. The implication to the Unruh effect in rainbow flat spacetime is also discussed.

A puzzle for the field ontologists

description: It has been widely thought that the wave function describes a real, physical field in a realist interpretation of quantum mechanics. In this paper, I present a new analysis of the field ontology for the wave function. First, I argue that the non-existence of self-interactions for a quantum system such as an electron poses a puzzle for the field ontologists. If the wave function represents a physical field, then it seems odd that there are (electromagnetic and gravitational) interactions between the fields of two electrons but no interactions between two parts of the field of an electron. Next, I argue that the three solutions a field ontologist may provide are not fully satisfactory. Finally, I propose a solution of this puzzle that leads to a particle ontological interpretation of the wave function.

......continued on the next page
 The female specimen was identified as Chronogaster africana based on morphometrics and morphology, especially the morphology of the tail terminus displaying a mucro with six short spines, and the absence of no crystalloids in the body cavity. The female specimen found in Telperion Nature Reserve (no males found) matches that of the original description by Heyns & Coomans (1980) with only difference being the length of the post-uterine branch (12.5 µm vs 6–9.5 µm). First time SEM observations on this species revealed the following: Lip region three annules long with four cephalic setae and amphid openings on second annule with their posterior margins protruding slightly. Amphid aperture with two protrusions towards inside. Cuticle shows distinct annules, no lateral field. Excretory pore located 140 µm from anterior end its opening one body annule wide. Lateral caudal pore on tail 30 µm posterior from anus on lateral side of body. This pore indicates two openings, one in the anterior and one in the posterior margin (Figure 10 B). Tail terminus consists of six small projections on the base of one larger mucro. In some instances, an extra projection noticed on larger mucro (Figure 10 C–F). Annules at the base of the tail tip showed some anastomoses / breaks in striations on lateral sides (Figure 10 F).
 Discussion. Chronogaster africana was first described in South Africa in 1980 from water sediment samples in Boskop Dam and The Kloof (North West Province), Natalspruit (Gauteng Province), and Krom River (Western Cape Province). It was then again reported in South Africa in 1992 from sand near the weir in the Sabie River near Lower Sabie (Mpumalanga Province) (Botha & Heyns 1992). As this species has been reported in this country only, it is considered endemic to South Africa.
 Locality and material examined: In the Telperion Nature Reserve a female specimen of C. africana was collected at the Wetland site (Table 1) with locality number MP00043 and deposited in the National Collection of Nematodes (ARC—Plant Health and Protection, Biosystematics, Pretoria) on slide number 50567.

description: In today's digital world, computing education offers critical opportunities, yet systemic inequities exclude under-represented communities, especially in rural, under-resourced regions. Early engagement is vital for building interest in computing careers and achieving equitable participation. Recent work has shown that the use of sensor-enabled tools and block-based programming can improve engagement and self-efficacy for students from under-represented groups, but these findings lack replication in diverse, resource-constrained settings. This study addresses this gap by implementing sensor-based programming workshops with rural students in Sri Lanka. Replicating methods from the literature, we conduct a between-group study (sensor vs. non-sensor) using Scratch and real-time environmental sensors. We found that students in both groups reported significantly higher confidence in programming in Scratch after the workshop. In addition, average changes in both self-efficacy and outcome expectancy were higher in the experimental (sensor) group than in the control (non-sensor) group, mirroring trends observed in the original study being replicated. We also found that using the sensors helped to enhance creativity and inspired some students to express an interest in information and communications technology (ICT) careers, supporting the value of such hands-on activities in building programming confidence among under-represented groups.

description: To avoid instabilities in the continuum semi-classical limit of loop quantum cosmology models, refinement of the underlying lattice is necessary. The lattice refinement leads to new dynamical difference equations which, in general, do not have a uniform step-size, implying complications in their analysis and solutions. We propose a numerical method based on Taylor expansions, which can give us the necessary information to calculate the wave-function at any given lattice point. The method we propose can be applied in any lattice-refined model, while in addition the accuracy of the method can be estimated. Moreover, we confirm numerically the stability criterion which was earlier found following a von Neumann analysis. Finally, the `motion' of the wave-function due to the underlying discreteness of the space-time is investigated, for both a constant lattice, as well as lattice refinement models.

Parents’ interpretation of psychoeducational results as a function of test score reporting format
Creators: name: Victor, Deborah Jane
Publisher: name: University of British Columbia
Year: 2009

description: This study investigated parents' comprehension of psychoeducational assessment results as a function of the type of norm-referenced test score reported and parental experience with psychoeducational assessments. Twenty-nine experienced parents and 37 non-experienced parents completed a questionnaire based on a fictitious assessment report containing intelligence and achievement test scores. The fictitious reports were varied by the type of norm-referenced score used to depict achievement test results. These test results were presented as percentile ranks, grade equivalents, or standard scores (M = 100, SD = 15) and were not significantly discrepant from intelligence test results which were presented as deviation IQ scores. The results indicated that parents were significantly more likely to overestimate the magnitude of the IQ-achievement discrepancy and perceive the presence of a learning disability when achievement scores were presented as percentile ranks or grade equivalents. In contrast, parents presented with standard scores made judgments consistent with the intelligence and achievement test data. They interpreted the scores more accurately and did not perceive a learning disability where the portrayed profile did not justify it. Parents' interpretations of the scores were not influenced by prior experience with psychoeducational assessment reports. Both experienced and non-experienced parents responded similarly across all three types of scores. The results of this study highlight the need for school psychologists to exercise caution when reporting norm-referenced test scores to parents.

description: Thermal leptogenesis in the canonical seesaw model in supersymmetry suffers from the incompatibility of a generic lower bound on the mass scale of the lightest right-handed neutrino and the upper bound on the reheating temperature of the Universe after inflation. This is resolved by adding an extra singlet superfield, with a discrete $Z_2$ symmetry, to the NMSSM (Next to Minimal Supersymmetric Standard Model). This generic mechanism is applicable to any supersymmetric model for lowering the scale of leptogenesis.

description: In many simulations of high-energy heavy-ion collisions on an event-by-event analysis, it is known that the initial energy density distribution in the transverse plane is highly fluctuating. Subsequent longitudinal expansion will lead to many longitudinal tubes of quark-gluon plasma which have tendencies to break up into many spherical droplets because of sausage instabilities. We are therefore motivated to use a model of quark-gluon plasma granular droplets that evolve hydrodynamically to investigate pion elliptic flows and Hanbury-Brown-Twiss interferometry. We find that the data of pion transverse momentum spectra, elliptic flows, and HBT radii in \sqrt{s_{NN}}=200 GeV Au + Au collisions at RHIC can be described well by an expanding source of granular droplets with an anisotropic velocity distribution.

description: Measurements of the two dimensional angular correlation of the electron-positron annihilation radiation have been done in the past to detect the momentum spin density and the Fermi surface. We point out that the momentum spin density and the Fermi Surface of ferromagnetic metals can be revealed within great detail owing to the large cancellation of the electron-positron matrix elements which in paramagnetic multiatomic systems plague the interpretation of the experiments. We prove our conjecture by calculating the momentum spin density and the Fermi surface of the half metal CrO2, who has received large attention due to its possible applications as spintronics material.

description: In this paper we describe our efforts towards the development of live performance computer-based musical instrumentation. Our design criteria include initial ease of use coupled with a long term potential for virtuosity, minimal and low variance latency, and clear and simple strategies for programming the relationship between gesture and musical result. We present custom controllers and unique adaptations of standard gestural interfaces, a programmable connectivity processor, a communications protocol called Open Sound Control (OSC), and a variety of metaphors for musical control. We further describe applications of our technology to a variety of real musical performances and directions for future research.

description: Photoactive materials hold great promise for a variety of applications. We present a finite element model of light-controlled flexible magnetic composite structure composed of 33.3% Chromium dioxide (CrO2) and 66.7% Polydimethylsiloxane (PDMS) by weight. The structure has a dimension of 8 mm x 2 mm x 100 um and has been previously experimentally studied. Due to the low Curie temperature, the structure acts as an actuator, shows significant deflection under the external magnetic field and relaxation due to laser heating. Thermal and magnetic deflection analysis has been performed using the FEM model. The simulation results show a maximum structural deflection of 6.08 mm (76% of the length of the structure) when subjected to 30 mT magnetic flux density and 160 mW laser power at 303 K (room temperature). We will present the results of the simulation model and comparison to experimental data reproducing the previously observed motion of the (CrO2+PDMS). This model will enable future fracture and fatigue analysis as well as extension to new photoactive geometries.

description: In this contribution we describe in some detail different aspects of the construction of BFKL cross sections. We focus on several effects which are relevant at next-to-leading order. In particular, we describe QCD coherence in DIS final states, improvements of the collinear region in multi-Regge kinematics, inclusive jet production at next-to-leading order, and azimuthal angle decorrelations of Mueller-Navelet jets at hadron colliders.

description: We present the results of a weekly monitoring of the new black hole candidate X-ray binary MAXI J1631-472 carried out with the MeerKAT radio interferometer, the Neil Gehrels Swift Observatory, and the Monitor of All-sky X-ray Image (MAXI) instrument, during its 2018-2019 outburst. The source exhibits a number of X-ray states, in particular both high- and low-luminosity hard states bracketed by extended soft states. Radio flaring is observed shortly after a transition from hard/intermediate states to the soft state. This is broadly in agreement with existing empirical models, but its extended duration hints at multiple unresolved flares and/or jet-ISM interactions. In the hard state radio:X-ray plane, the source is revealed to be 'radio quiet' at high luminosities, but to rejoin the `standard' track at lower luminosities, an increasingly commonly-observed pattern of behaviour.

description: Presented in this paper is a Markov chain Monte Carlo (MCMC) routine for conducting coherent parameter estimation for interferometric gravitational wave observations of an inspiral of binary compact objects using data from multiple detectors. The MCMC technique uses data from several interferometers and infers all nine of the parameters (ignoring spin) associated with the binary system, including the distance to the source, the masses, and the location on the sky. The Metropolis-algorithm utilises advanced MCMC techniques, such as importance resampling and parallel tempering. The data is compared with time-domain inspiral templates that are 2.5 post-Newtonian (PN) in phase and 2.0 PN in amplitude. Our routine could be implemented as part of an inspiral detection pipeline for a world wide network of detectors. Examples are given for simulated signals and data as seen by the LIGO and Virgo detectors operating at their design sensitivity.

Near-Infrared Photometric Study of the Galactic Open Clusters NGC 1641 and NGC 2394 Based on 2MASS Data

description: We present JHKs near-infrared CCD photometric study for the Galactic open clusters NGC 1641 and NGC 2394. These clusters have never been studied before, and we provide, for the first time, the cluster parameters; reddening, distance, metallicity and age. NGC 1641 is an old open cluster with age 1.6 +/- 0.2 Gyr, metallicity [Fe/H] = 0.0 +/- 0.2 dex, distance modulus (m-M)_0 = 10.4 +/- 0.3 mag (d = 1.2 +/- 0.2 kpc), and reddening E(B-V) = 0.10 +/- 0.05 mag. The parameters for the other old open cluster NGC 2394 are estimated to be age = 1.1 +/- 0.2 Gyr, [Fe/H] = 0.0 +/- 0.2 dex, (m-M)_0 = 9.1 +/- 0.4 mag (d = 660 +/- 120 pc), and E(B-V) = 0.05 +/- 0.10 mag. The metallicities and distance values for these two old open clusters are consistent with the relation between the metallicities and the Galactocentric distances of other old open clusters. We find the metallicity gradient of 53 old open clusters including NGC 1641 and NGC 2394 to be Delta [Fe/H]/Delta R_gc = -0.067 +/- 0.009 dex/kpc.

Sino-Japanese trade in the early Tokugawa period: kango, copper, and shinpai
Creators: name: Tang, Yun
Publisher: name: University of British Columbia
Year: 2009

description: This thesis surveys Sino-Japanese relations in the early Tokugawa period with a specific focus on transactions in the major commodity--copper--between the two countries. The main purpose of the research is to investigate the bilateral contact in the early Tokugawa, the evolution of the copper trade, the political events involved with the trade, and to reexamine the significance of sakoku (seclusion) policy of Japan from a Chinese perspective. This thesis first explores the efforts of the shogunate from 1600 to 1625 towards reopening the kango or tally trade with China which had been suspended in the previous Muromachi period. Based on research of the archives of the Ming imperial court, this study for the first time demonstrates the Chinese response to their efforts. The thesis goes on to survey the copper problem in China, the Qing court copper policy, and the copper trade between Japan and the Qing. The discussion includes concern with China's internal economic and monetary situation and its external trade with Japan, the Kangxi Emperor's direct involvement with the copper trade, particularly from 1684 to 1715, and the control over the trade by the bakufu. Finally, the thesis presents a thorough examination of the case of shinpai (trade credentials) in China triggered by the "Shotoku New Regulations" issued by the bakufu in 1715, and takes the shinpai case and the imperial edict of the Kangxi Emperor on the case as a touchstone and clue to the understanding of Sino- Japanese relations in the whole Tokugawa period. The study concludes that the sakoku policy had a positive impact on Sino- Japanese relations in the Tokugawa (Qing) period.
On a non-archimedean broyden method

description: Newton's method is an ubiquitous tool to solve equations, both in the archimedean and non-archimedean settings -- for which it does not really differ. Broyden was the instigator of what is called "quasi-Newton methods". These methods use an iteration step where one does not need to compute a complete Jacobian matrix nor its inverse. We provide an adaptation of Broyden's method in a general non-archimedean setting, compatible with the lack of inner product, and study its Q and R convergence. We prove that our adapted method converges at least Q-linearly and R-superlinearly with R-order $2^{\frac{1}{2m}}$ in dimension m. Numerical data are provided.
Resonant Processing of Instrumental Sound Controlled by Spatial Position

description: We present an acoustic musical instrument played through a resonance model of another sound. The resonance model is controlled in real time as part of the composite instrument. Our implementation uses an electric violin, whose spatial position modifies filter parameters of the resonance model. Simplicial interpolation defines the mapping from spatial position to filter parameters. With some effort, pitch tracking can also control the filter parameters. The individual technologies -- motion tracking, pitch tracking, resonance models -- are easily adapted to other instruments.

On the scaling properties of 2d randomly stirred Navier--Stokes equation

description: We inquire the scaling properties of the 2d Navier-Stokes equation sustained by a forcing field with Gaussian statistics, white-noise in time and with power-law correlation in momentum space of degree $2-2 \eps$. This is at variance with the setting usually assumed to derive Kraichan's classical theory. We contrast accurate numerical experiments with the different predictions provided for the small $\eps$ regime by Kraichnan's double cascade theory and by renormalization group (RG) analysis. We give clear evidence that for all $\eps$ Kraichnan's theory is consistent with the observed phenomenology. Our results call for a revision in the RG analysis of (2d) fully developed turbulence.

Associated production of a light pseudoscalar Higgs boson with a chargino pair in the NMSSM

description: In the next-to-minimal supersymmetric standard model (NMSSM), the unique $λS H_u H_d$ in the superpotential gives rise to a coupling involving the lighter pseudoscalar Higgs boson and a pair of charged or neutral Higgsinos, even in the limit of zero mixing between the two pseudoscalar Higgs bosons. We study the associated production of a very light pseudoscalar Higgs boson with a pair of charginos. The novel signature involves a pair of charged leptons from chargino decays and a pair of photons from the pseudoscalar Higgs boson decay, plus large missing energy at the LHC and ILC. The signal may help us to distinguish the NMSSM from MSSM, provided that the experiment can resolve the two photons from the decay of the pseudoscalar Higgs boson.
