The cross section for Higgs boson production in pp collisions is studied using the H → W+W− decay mode, followed by leptonic decays of the W bosons to an oppositely charged electron-muon pair in the final state. The measurements are performed using data collected by the CMS experiment at the LHC at a centre-of-mass energy of 8 TeV, correspondin

One of the major challenges facing developing nations like Nigeria is the continuous increase in the level of poverty, which widens the gap between the rich and the poor amidst increasing population and economic growth. In Nigeria, there are scores of microfinance outlets but their operational products are yet to stem the tides of people falling in

A measurement of the t¯t production cross section at √ s = 13 TeV is presented using proton-proton collisions, corresponding to an integrated luminosity of 2.2 fb−1 , collected with the CMS detector at the LHC. Final states with one isolated charged lepton (electron or muon) and at least one jet are selected and categorized according to the ac

Pair production of Υ(1S) mesons is observed at the LHC in proton-proton collisions at √ s = 8 TeV by the CMS experiment in a data sample corresponding to an integrated luminosity of 20.7 fb−1 . Both Υ(1S) candidates are fully reconstructed via their decays to µ +µ −. The fiducial acceptance region is defined by an absolute Υ(1S) rapidity

Cross sections for the production of a Z boson in association with jets in proton-proton collisions at a centre-of-mass energy of √ s = 8 TeV are measured using a data sample collected by the CMS experiment at the LHC corresponding to 19.6 fb−1 . Differential cross sections are presented as functions of up to three observables that describe the

The transverse momentum spectra of weak vector bosons are measured in the CMS experiment at the LHC. The measurement uses a sample of proton-proton collisions at s=8 TeV, collected during a special low-luminosity running that corresponds to an integrated luminosity of 18.4 ± 0.5 pb−1. The production of W bosons is studied in both electron and mu

Introduction: We conducted a nationally representative study to identify characteristics of current (e-cigarette users, conventional cigarette smokers, and dual users), former and never smokers linked to perceptions of harm and benefit associated with e-cigarette use. Methods: A crosssectional questionnaire survey of 1,987 adults (≥18 years) male

The present study focused on the preparation of nanohydroxyapatite (nHA)-coated hydroxyethyl cellulose/polyvinyl alcohol (HEC/PVA) nanofibrous scaffolds for bone tissue engineering application. The electrospun HEC/PVA scaffolds were mineralized via alternate soaking process. FESEM revealed that the nHA was formed uniformly over the nanofibers. The

Jet charge is an estimator of the electric charge of a quark, antiquark, or gluon initiating a jet. It is based on the momentum-weighted sum of the electric charges of the jet constituents. Measurements of three charge observables of the leading jet in transverse momentum pT are performed with dijet events. The analysis is carried out with ata coll
