Search for additional neutral MSSM Higgs bosons in the τ τ final state in proton-proton collisions at √s=13 TeV

Abstract: A search is presented for additional neutral Higgs bosons in the τ τ final state in proton-proton collisions at the LHC. The search is performed in the context of the minimal supersymmetric extension of the standard model (MSSM), using the data collected with the CMS detector in 2016 at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb−1. To enhance the sensitivity to neutral MSSM Higgs bosons, the search includes production of the Higgs boson in association with b quarks. No significant deviation above the expected background is observed. Model-independent limits at 95% confidence level (CL) are set on the product of the branching fraction for the decay into τ leptons and the cross section for the production via gluon fusion or in association with b quarks. These limits range from 18 pb at 90 GeV to 3.5 fb at 3.2 TeV for gluon fusion and from 15 pb (at 90 GeV) to 2.5 fb (at 3.2 TeV) for production in association with b quarks, assuming a narrow width resonance. In the m h hod + scenario these limits translate into a 95% CL exclusion of tan β > 6 for neutral Higgs boson masses below 250 GeV, where tan β is the ratio of the vacuum expectation values of the neutral components of the two Higgs doublets. The 95% CL exclusion contour reaches 1.6 TeV for tan β = 60.

Analysis of critical success factors of humanitarian supply chain: An application of Interpretive Structural Modeling

Abstract: With increasing frequency and intensity of disasters and large number of people being affected by them, the subject needs more attention and a planned approach. And in order to reduce the adverse impact of disasters and to improve the disaster relief practices, academicians and practitioners are emphasizing on a number of diverse factors of humanitarian supply chain by segmenting them into different clusters. This research is intended to address the critical success factors (CSFs) of humanitarian supply chain which emerges during disaster preparedness and immediate response phase. Through a review of literature and expert consultation, 12 critical success factors leading to responsive humanitarian supply chains have been identified. In this paper, the authors have used Interpretive Structural Modeling (ISM) approach to interpret the interdependency among the selected CSFs. In addition, MICMAC (Matrice d'Impacts Croises Multiplication Appliquee a un Classement (cross-impact matrix multiplication applied to classification)) analysis is also used to illustrate the relative driving and dependence power among the selected factors. This paper argues that, Government policies and Organizational structure is the most dominating factor which has the highest driving power and the minimum dependence power as it drive others factors and forms the base of interpretive structure model. The outcome of this research presents the insight of humanitarian supply chain practices and discussion from both a researcher and managerial perspective is also summarized.

Search for supersymmetry in proton-proton collisions at 13 TeV in final states with jets and missing transverse momentum

Abstract: Results are reported from a search for supersymmetric particles in the final state with multiple jets and large missing transverse momentum. The search uses a sample of proton-proton collisions at $ \sqrt{s} $ = 13 TeV collected with the CMS detector in 2016–2018, corresponding to an integrated luminosity of 137 fb$^{−1}$, representing essentially the full LHC Run 2 data sample. The analysis is performed in a four-dimensional search region defined in terms of the number of jets, the number of tagged bottom quark jets, the scalar sum of jet transverse momenta, and the magnitude of the vector sum of jet transverse momenta. No significant excess in the event yield is observed relative to the expected background contributions from standard model processes. Limits on the pair production of gluinos and squarks are obtained in the framework of simplified models for supersymmetric particle production and decay processes. Assuming the lightest supersymmetric particle to be a neutralino, lower limits on the gluino mass as large as 2000 to 2310 GeV are obtained at 95% confidence level, while lower limits on the squark mass as large as 1190 to 1630 GeV are obtained, depending on the production scenario.
