A search for single production of vector-like top quark partners (T) decaying into a Higgs boson and a top quark is performed using data from pp collisions at a centre-of-mass energy of 13 TeV collected by the CMS experiment at the CERN LHC, corresponding to an integrated luminosity of 2.3 fb−1. The top quark decay includes an electron or a muon

This study explored IIUM TESL pre-service teachers’ motivation level to integrate critical thinking in their teaching and the influence of ‘year of study’ towards their motivation. A total of 106 TESL students from Kuliyyah of Education, IIUM participated in a questionnaire survey that measures motivation on a 5-point Likert scale. The data w

A measurement of electroweak-induced production of Wγ and two jets is performed, where the W boson decays leptonically. The data used in the analysis correspond to an integrated luminosity of 19.7 fb−1 collected by the CMS experiment in √ s = 8 TeV proton-proton collisions produced at the LHC. Candidate events are selected with exactly one muo

Problem solving is considered important in the learning of mathematics because it develops the logical thinking aspect of doing mathematics. Thus it allows students to reason, communicate ideas, and employ knowledge to new and different variation of problems and situations. In the most recent Programme for International Student Assessment (PISA) re

The spectra of charged particles produced within the pseudorapidity window |η| < 1 at √ sNN = 5.02 TeV are measured using 404 µb −1 of PbPb and 27.4 pb−1 of pp data collected by the CMS detector at the LHC in 2015. The spectra are presented over the transverse momentum ranges spanning 0.5 < pT < 400 GeV in pp and 0.7 < pT &#

A search for supersymmetry is performed in events with a single electron or muon in proton-proton collisions at a center-of-mass energy of 13 TeV. The data were recorded by the CMS experiment at the LHC and correspond to an integrated luminosity of 2.3 fb−1. Several exclusive search regions are defined based on the number of jets and b-tagged jet

A search for the production of heavy resonances decaying into top quarkantiquark pairs is presented. The analysis is performed in the lepton+jets and fully hadronic channels using data collected in proton-proton collisions at √ s = 13 TeV using the CMS detector at the LHC, corresponding to an integrated luminosity of 2.6 fb−1 . The selection is

Searches for invisible decays of the Higgs boson are presented. The data collected with the CMS detector at the LHC correspond to integrated luminosities of 5.1, 19.7, and 2.3 fb−1 at centre-of-mass energies of 7, 8, and 13 TeV, respectively. The search channels target Higgs boson production via gluon fusion, vector boson fusion, and in associati

A search for heavy narrow resonances decaying into four-lepton final states has been performed using proton–proton collision data at √s = 8 TeV collected by the CMS experiment, corresponding to an integrated luminosity of 19.7 fb−1. No excess of events over the standard model background expectation is observed. Upper limits for a benchmark mo

The cross section for coherent J/ψ photoproduction accompanied by at least one neutron on one side of the interaction point and no neutron activity on the other side, Xn0n, is measured with the CMS experiment in ultra-peripheral PbPb collisions at √sN N = 2.76 TeV. The analysis is based on a data sample corresponding to an integrated luminosity
