Search for Resonances in the Dilepton Mass Distribution in pp Collisions at sqrt(s) = 7 TeV
Creators: name: CMS Collaboration
Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: A search for narrow resonances at high mass in the dimuon and dielectron channels has been performed by the CMS experiment at the CERN LHC, using pp collision data recorded at sqrt(s)=7 TeV. The event samples correspond to integrated luminosities of 40 inverse picobarns in the dimuon channel and 35 inverse picobarns in the dielectron channel. Heavy dilepton resonances are predicted in theoretical models with extra gauge bosons (Z') or as Kaluza-Klein graviton excitations(G_KK) in the Randall-Sundrum model. Upper limits on the inclusive cross section of Z'(G_KK) decaying to oppositely charged leptons relative to Z decaying to oppositely charged leptons are presented. These limits exclude at 95% confidence level a Z' with standard-model-like couplings below 1140 GeV, the superstring-inspired Z_psi below 887 GeV, and, for values of the coupling parameter k/M_Pl of 0.05 (0.1), Kaluza-Klein gravitons below 855 (1079) GeV.

description: We study Feynman rules for the rational part $R$ of the Standard Model amplitudes at one-loop level in the 't Hooft-Veltman $γ_5$ scheme. Comparing our results for quantum chromodynamics and electroweak 1-loop amplitudes with that obtained based on the Kreimer-Korner-Schilcher (KKS) $γ_5$ scheme, we find the latter result can be recovered when our $γ_5$ scheme becomes identical (by setting $g5s=1$ in our expressions) with the KKS scheme. As an independent check, we also calculate Feynman rules obtained in the KKS scheme, finding our results in complete agreement with formulae presented in the literature. Our results, which are studied in two different $γ_5$ schemes, may be useful for clarifying the $γ_5$ problem in dimensional regularization. They are helpful to eliminate or find ambiguities arising from different dimensional regularization schemes.

description: Two established frameworks account for the onset of a gap in a superconducting system: one is based on spontaneous symmetry breaking via the Anderson-Higgs-Kibble mechanism, and the other is based on the recently developed paradigm of topological order. We show that, on manifolds with non trivial topology, both mechanisms yield a degeneracy of the ground state arising only from the {\it incompressibility} induced by the presence of a gap. We compute the topological entanglement entropy of a topological superconductor and argue that its measure allows to {\it distinguish} between the two mechanisms of generating a superconducting gap.

Activists across issues : forum multiplying and the new climate change activism
Creators: name: Allan, Jen Iris
Publisher: name: University of British Columbia
Year: 2017

description: To a growing class of climate change activists, climate change is not only an environmental issue – it is a labour, gender, justice, indigenous rights, and faith (to name a few) issue. All starting at roughly the same time, an influx of non-governmental organizations (NGOs) made social claims on an environmental issue and changed the politics of climate governance. Their participation to advance these social claims is costly: staff retrained; information researched, analyzed, and disseminated; and relationship building undertaken. All these costs served a new frame, linking the NGOs’ social issue to climate change. This sustained mobilization of a network of NGOs in a regime that is not their own is called forum multiplying. NGOs are surprisingly mobile, as environmentalists campaign on free trade and development issues, and unions and children’s advocates work in the context of human rights. Drawing on 72 interviews, seven social network analyses, and three years of participant observation, this research investigates the politics of forum multiplying as NGOs seek recognition within a new area of global governance. NGO networks engage in forum multiplying to contribute to solutions, recruit new allies to their cause, and avoid becoming mired in stalemates that characterize other areas of global governance. Motivation is insufficient to mobilize a network toward a collective end. I posit that two mechanisms help explain why some NGO networks undertake forum multiplying strategies and others do not. First, the ability of NGOs to capitalize on the authority that they hold in their traditional forum, and to bring that authority into the new forum helps them secure recognition for their claims. Second, NGOs’ identification of strategic entry points in the rules and norms of the new regime facilitates forum multiplying. The rules and norms of a regime can provide a discursive “hook” for the NGOs’ claims that their issue is linked to the issues of their targeted regime, showing that they belong. Forum multiplying pollinates new ideas into old regimes, potentially bringing the “all hands on deck” approach necessary to mobilize a sufficient response to global climate change.

description: A new approach to jet-shape identification based on linear regression is discussed. It is designed for searches for new particles at the TeV scale decaying hadronically with strongly collimated jets. We illustrate the method using a Monte Carlo simulation for pp collisions at the LHC with the goal to reduce the contribution of QCD-induced events. We focus on a rather generic example X to ttbar to hadrons, with X being a heavy particle, but the approach is well suited for reconstruction of other decay channels characterized by a cascade decay of known states.

description: Σε μια παγκοσμιοποιημένη εποχή, όπου συντελούνται ραγδαίες αλλαγές και εξελίξεις παρατηρείται όλο και εντονότερη πολιτισμική ποικιλομορφία, η οποία αντικατοπτρίζεται καθημερινά στις σχολικές αίθουσες. Παιδιά προερχόμενα από διαφορετικά πολιτισμικά περιβάλλοντα καλούνται να ενταχθούν σε ένα σχολικό πλαίσιο αλλά και μια πραγματικότητα που πιθανότατα διαφέρει αρκετά από τα μέχρι τώρα δεδομένα τους. H αποδοχή της διαφορετικότητας, ο αλληλοσεβασμός, η επικοινωνία και η ενσυναίσθηση αποτελούν καίριες παραμέτρους για την ομαλή ενσωμάτωση των παιδιών αυτών στην ελληνική σχολική, και όχι μόνο, πραγματικότητα. Η μουσική είναι ένας τρόπος επικοινωνίας και έκφρασης συναισθημάτων και μπορεί να βοηθήσει τα παιδιά να μάθουν και να αναπτυχθούν. Οι μουσικές δραστηριότητες μπορούν να τα βοηθήσουν να συνδεθούν μεταξύ τους, να τους προκαλέσουν συναισθήματα και να τους προσφέρουν νέα ερεθίσματα. Η παρούσα εργασία αποτελεί ένα πρόγραμμα παρέμβασης με στόχο να βοηθήσει στη βελτίωση των δεξιοτήτων διαπολιτισμικής επικοινωνίας των μαθητών του δημοτικού σχολείου μέσα από διαπολιτισμικές μουσικές/μουσικοκινητικές και πολυγλωσσικές δραστηριότητες.
description: In a globalized era, where rapid changes and developments are taking place, an increasingly intense cultural diversity is observed, which is reflected every day in the school classrooms. Children from different cultural backgrounds are invited to join a school context but also a reality that is probably quite different from what they have experienced so far. The acceptance of diversity, mutual respect, communication and empathy are key parameters for the smooth integration of these children into the Greek school, and not only, reality. Music is a way of communicating and expressing emotions and can help children learn and develop. Musical activities can help them connect with each other, evoke emotions and provide them with new stimuli. This thesis is an intervention program aimed at helping to improve the intercultural communication skills of elementary school students through intercultural music/music and movement and multilingual activities.

description: This study investigates the application of gamification as a strategy for attracting and selecting human resources. Specifically, we conducted an experiment comparing gamification with the situational judgement test. The aim is to validate or refute the research hypotheses, which were developed following a comprehensive bibliographic analysis. First, the study provides a bibliographical overview that illuminates the central concepts. It delves into Human Resources Management, particularly emphasizing the attraction and selection processes, then transitions into an examination of gamification, and lastly to the utilization of education as a strategy for attracting and selecting potential employees. Subsequently, the study formulates two research hypotheses, focusing on organizational attractiveness as the subject of investigation. This is followed by a presentation of the research methodology and an analysis of the results. Finally, the conclusions derived from the research are presented and thoroughly analyzed.

We pay particular attention to the minimization and maximization of the polarization of the top quark by tuning the longitudinal polarization of the e^+ and e^- beams. The polarization of the top quark is calculated in full next-to-leading order QCD. We also discuss the beam polarization dependence of the longitudinal spin-spin correlations of the top and antitop quark spins.

We compare the end-state of the collapse with the trumpet solution found in the evolution of a single wormhole slice and show that the two solutions closely agree. We demonstrate that the agreement is caused by the use of the Gamma-driver shift condition, which allows the matter to fall inwards into a region of spacetime that is not resolved by the numerical grid, and which simultaneously finds the stationary coordinates of the trumpet outside the matter.

description: In der Schweiz ist die sozialhilferechtliche Mindestsicherung föderal organisiert und obliegt in vielen Kantonen den einzelnen Gemeinden. Viele Gemeinden lagern aus wirtschaftlichen Gründen ihre ei-genen Sozialdienste an profitorientierte Unternehmen der Sozialhilfe aus. Die vorliegende explorative Forschungsarbeit befasst sich mit Professionsverständnissen von Sozial-arbeitenden in den profitorientierten Unternehmen im Bereich Sozialhilfe in den Kantonen Aargau, Solothurn sowie Basel-Landschaft. Es wird dabei mittels des interaktionistischen Professionsmodells nach Fritz Schütze sowie seinen Paradoxien Professionellen Handelns untersucht, wie Sozialarbeiten-de in profitorientierten Unternehmen ihre Arbeitsbeziehung mit den Klient*innen beurteilen. Im Rahmen dieser Arbeit wurden insgesamt drei Leitfadeninterviews mit Sozialarbeitenden in profit-orientierten Unternehmen durchgeführt, transkribiert sowie unter Verwendung von Grounded Theo-ry analysiert. Die Ergebnisse der Analyse zeigen, dass Sozialarbeitende in profitorientierten Unter-nehmen hohe Anpassungsleistungen gegenüber den potentiellen Kund*innen erbringen und ihr pro-fessionelles Selbstverständnis durch dienstleistungsorientierte Anteile ergänzen oder teilweise über-lagern. Des Weiteren wurden die konkreten Arbeitsbedingungen der Sozialarbeitenden in diesen Un-ternehmen genauer beleuchtet und mit ihren Vorerfahrungen in Gemeindesozialdiensten verglichen.

description: We report on the discovery of \geq 100 MeV γ rays from the binary system PSR B1259-63/LS 2883 using the Large Area Telescope (LAT) on board Fermi. The system comprises a radio pulsar in orbit around a Be star. We report on LAT observations from near apastron to ~ 60 days after the time of periastron, tp, on 2010 December 15. No γ-ray emission was detected from this source when it was far from periastron. Faint γ-ray emission appeared as the pulsar approached periastron. At ~ tp + 30d, the \geq 100 MeV γ-ray flux increased over a period of a few days to a peak flux 20-30 times that seen during the pre-periastron period, but with a softer spectrum. For the following month, it was seen to be variable on daily time scales, but remained at ~ 1 - 4 \times 10^-6 cm^-2 s^-1 before starting to fade at ~ tp + 57d. The total γ-ray luminosity observed during this period is comparable to the spin-down power of the pulsar. Simultaneous radio and X-ray observations of the source showed no corresponding dramatic changes in radio and X-ray flux between the pre-periastron and post-periastron flares. We discuss possible explanations for the observed γ-ray-only flaring of the source.

Deliverable 4.3 is the mid-term report of all dissemination and communication activities that have been achieved since the beginning of the project (Month 1) and until Month 24, as part of Work Package (WP) 4 and in alignment with the Plan for Dissemination and Exploitation of Results (PEDR) that was issued at Month 6 as Deliverable 4.2 and already revised once at the end of the Reporting Period 1 (M18). Deliverable 4.3 provides an overview of the strategy for communicating and disseminating Co-UDlabs actions and results and then provides a detailed and exhaustive list of all communication and dissemination activities performed since the beginning of the project, including the evaluation of the Key Performance Indicators set for these actions. In summary, the dissemination and communication activities are on track, with most of the KPIs for the period achieved, overstepping in some cases the expectations (see Annex 2 for details). Some KPIs related to dissemination are not yet achieved because these first 2 years were mainly dedicated to raise awareness on the project and its activities (communication). The next reporting periods will be much more dedicated to dissemination activities since we will have much more results resulting from JRA activities and transnational access to research infrastructures so we are very confident that we will reach the expected targets in all KPIs.

description: We introduce a new simplified method for computing the electron field emission current in short carbon nanotubes using ab-initio computation in periodic simulation cells. We computed the evolution of the wave functions using Time-Dependent Density Functional Theory, where we have utilized the Crank-Nicholson propagator. We found that in pristine carbon nanotubes, the emitted charge tends to emerge mostly from electrons that are concentrated at the nanotube tip region. The charge beam concentrates into specific channel structures, showing the utility of carbon nanotubes in precision emission applications.

description: Measurements of the magnetic penetration depth (lambda) in the Fe-based superconductor Ba_(1-x)Rb_xFe_2As_2 (x=0.3, 0.35, 0.4) were carried out using the muon-spin rotation muSR technique. The temperature dependence of lambda is well described by a two-gap s+s-wave scenario with a small gap Delta_1 = 1 - 3 mev and a large gap Delta_2 = 7 - 9 mev. By combining the present data with those obtained for RbFe_2As_2 a decrease of the BCS ratio 2Delta_2/(k_B)(T_c) with increasing Rb content x is observed. On the other hand, the BCS ratio 2Delta_1/(k_B)(T_c) is almost independent of x. In addition, the contribution of Delta_1 to the superfluid density is found to increase with x. These results are discussed in the light of the suppression of interband processes upon hole doping.

description: The present diploma thesis discusses the creation of a digital museum for the ancient city of Tenea. The theme of the digital exhibition is about the discovery of the lost city and its citizens based on the Hellenistic and Roman cemetery of the city. After carrying out the Conceptual Exhibition Planning and Design emerges the final proposal of this thesis. The theoretical framework of digital museums is analyzed in the first chapter and subsequently is presented the Exhibition Planning, generated by the exploration and further processing of the characteristics of the Collection, the Project Owner and its intentions, the Space, the Public and the Cultural and Natural Environment. Taking the results of the Exhibition Planning into account is constructed the Conceptual Design of the exhibition entitled “Tenea emerges from the ruins: people and practices”. The exhibition aims to present the identity of the community of the ancient Tenea during the Hellenistic and Roman times. This acquaintance with the ancient city is achieved through the analysis of multiple identities that the citizens reveal. The visitor is asked to take the place of an archeologist and to discover them.

description: We describe a model structure for coloured operads with values in the category of symmetric spectra (with the positive model structure), in which fibrations and weak equivalences are defined at the level of the underlying collections. This allows us to treat R-module spectra (where R is a cofibrant ring spectrum) as algebras over a cofibrant spectrum-valued operad with R as its first term. Using this model structure, we give suficient conditions for homotopical localizations in the category of symmetric spectra to preserve module structures.

description: We present Cygnus X in a new multi-wavelength perspective based on an unbiased BLAST survey at 250, 350, and 500 micron, combined with rich datasets for this well-studied region. Our primary goal is to investigate the early stages of high mass star formation. We have detected 184 compact sources in various stages of evolution across all three BLAST bands. From their well-constrained spectral energy distributions, we obtain the physical properties mass, surface density, bolometric luminosity, and dust temperature. Some of the bright sources reaching 40 K contain well-known compact H II regions. We relate these to other sources at earlier stages of evolution via the energetics as deduced from their position in the luminosity-mass (L-M) diagram. The BLAST spectral coverage, near the peak of the spectral energy distribution of the dust, reveals fainter sources too cool (~ 10 K) to be seen by earlier shorter-wavelength surveys like IRAS. We detect thermal emission from infrared dark clouds and investigate the phenomenon of cold ``starless cores" more generally. Spitzer images of these cold sources often show stellar nurseries, but these potential sites for massive star formation are ``starless" in the sense that to date there is no massive protostar in a vigorous accretion phase. We discuss evolution in the context of the L-M diagram. Theory raises some interesting possibilities: some cold massive compact sources might never form a cluster containing massive stars; and clusters with massive stars might not have an identifiable compact cold massive precursor.

Intrinsic Bispectra of Cosmic Magnetic Fields

description: Forthcoming datasets from the Planck experiment and others are in a position to probe the CMB non-Gaussianity with higher accuracy than has yet been possible and potentially open a new window into the physics of the very early universe. However, a signal need not necessarily be inflationary in origin, and possible contaminants should be examined in detail. One such is provided by early universe magnetic fields, which can be produced by a variety of models including during an inflationary phase, at phase transitions, or seeded by cosmic defects. Should such fields have been extent in the early universe they provide a natural source of CMB non-Gaussianity. Knowledge of the CMB angular bispectrum requires the complete Fourier-space (or "intrinsic") bispectrum. In this paper I consider in detail the intrinsic bispectra of an early-universe magnetic field for a range of power-law magnetic power spectra.

description: Ανάμεσα στα δεκάδες τακτικά συστήματα παράταξης ομάδων, και ειδικότερα την τελευταία δεκαετία, το 1-4-3-3 δείχνει να προτιμάται περισσότερο από τους ειδικούς (έχοντας ή μη το κατάλληλο υλικό..), σύστημα το οποίο εδώ και χρόνια αποτελεί το υπόδειγμα ομοσπονδιών ώστε να αναπτύσσονται γενιές και να αντιπροσωπεύονται έθνη επ’αυτού. Με την ευκαιρία λοιπόν της διοργάνωσης του Παγκοσμίου Κυπέλλου του Κατάρ (2022), γεννιέται η ανάγκη να δοθούν απαντήσεις με τη βοήθεια των νέων τεχνολογιών (τακτική ανάλυση αλλά και στατιστικά δεδομένα) στο κατά πόσο πετυχημένη είναι η εγκαθίδρυση του και πόσο καλά εξυπηρετείται με βάση πάντα τις αρχές του αθλήματος (θέσεις, αμυντικές και επιθετικές αρχές, αριθμοί φάσεων, αναπτύξεων, x Goals, κλπ.). Όλα λοιπόν κρίνονται από το αποτέλεσμα, αλλά ίσως αξίζει να εξεταστεί και το πόσο αποτελεσματικό είναι σε τέτοια τουρνουά, λίγων αλλά τόσο σημαντικών παιχνιδιών για τα έθνη ανά τον κόσμο. Η έρευνα θα προσπαθήσει με τη χρήση του Excel και της παρακολούθησης όλων των αγώνων του Mundial, να μελετήσει την επιρροή της πλέον προτιμώμενης διάταξης σε κορυφαίο επίπεδο.
description: Of all the formations used so far, with emphasis on the last decade, the 1-4-3-3 is favored by the teams and technical staff, a system which constitutes the basis on which new generations are developed and nations are represented. With the World Cup of Qatar taking place, an opportunity to try and analyze in depth the aforementioned formation is given, with the help of tools like tactical analysis and statistical data, and figure out whether or not the establishment of the formation is well deserved and how well is faring based on the core principles of the sport (e.g. positions, offensive and defensive standards, goal-scoring probability, team advancement in the field, goals scored). Even though everything is judged by the results, maybe it’s worthwhile to take a deeper look at how effective the formation have been at major tournaments like the World Cup, with few but very important games for the National teams taking place. This research with the help of the Excel system and the live monitoring of the games, will try to examine how these games are affected by the above formation.
Theory of excitons in cubic III-V semiconductor GaAs, InAs and GaN quantum dots: fine structure and spin relaxation

description: Exciton fine structures in cubic III-V semiconductor GaAs, InAs and GaN quantum dots are investigated systematically and the exciton spin relaxation in GaN quantum dots is calculated by first setting up the effective exciton Hamiltonian. The electron-hole exchange interaction Hamiltonian, which consists of the long- and short-range parts, is derived within the effective-mass approximation by taking into account the conduction, heavy- and light-hole bands, and especially the split-off band. The scheme applied in this work allows the description of excitons in both the strong and weak confinement regimes. The importance of treating the direct electron-hole Coulomb interaction unperturbatively is demonstrated. We show in our calculation that the light-hole and split-off bands are negligible when considering the exciton fine structure, even for GaN quantum dots, and the short-range exchange interaction is irrelevant when considering the optically active doublet splitting. We point out that the long-range exchange interaction, which is neglected in many previous works, contributes to the energy splitting between the bright and dark states, together with the short-range exchange interaction. Strong dependence of the optically active doublet splitting on the anisotropy of dot shape is reported. Large doublet splittings up to 600 $μ$eV, and even up to several meV for small dot size with large anisotropy, is shown in GaN quantum dots. The spin relaxation between the lowest two optically active exciton states in GaN quantum dots is calculated, showing a strong dependence on the dot anisotropy. Long exciton spin relaxation time is reported in GaN quantum dots. These findings are in good agreement with the experimental results.

Species assembly in model ecosystems, I: Analysis of the population model and the invasion dynamics

Subjects: subject: Populations and Evolution (q-bio.PE)

description: Recently we have introduced a simplified model of ecosystem assembly (Capitan et al., 2009) for which we are able to map out all assembly pathways generated by external invasions in an exact manner. In this paper we provide a deeper analysis of the model, obtaining analytical results and introducing some approximations which allow us to reconstruct the results of our previous work. In particular, we show that the population dynamics equations of a very general class of trophic-level structured food-web have an unique interior equilibrium point which is globally stable. We show analytically that communities found as end states of the assembly process are pyramidal and we find that the equilibrium abundance of any species at any trophic level is approximately inversely proportional to the number of species in that level. We also find that the per capita growth rate of a top predator invading a resident community is key to understand the appearance of complex end states reported in our previous work. The sign of these rates allows us to separate regions in the space of parameters where the end state is either a single community or a complex set containing more than one community. We have also built up analytical approximations to the time evolution of species abundances that allow us to determine, with high accuracy, the sequence of extinctions that an invasion may cause. Finally we apply this analysis to obtain the communities in the end states. To test the accuracy of the transition probability matrix generated by this analytical procedure for the end states, we have compared averages over those sets with those obtained from the graph derived by numerical integration of the Lotka-Volterra equations. The agreement is excellent.
