Background: Internet today has become a greater part of every citizen’s life which helps many successful although, many fall in failure if not utilize it carefully. The usage of Internet is bringing welfare of mankind while avoiding different types of drawback, many of us unable to identify it. This study measured the level of Internet addiction

ومن أبرز النقوش في أدب العراق القديم هي ملحمة جلجامش التي دُوِّنت قبل 4000 عام - حيث ترجمتها - كانت عن موضوع البطولة الخالدة، وقد عالجت قضايا إنسانية كمشكلة الحياة والموت وما بعد الموت والخلود وغ�

Measurements of the top quark polarization and top quark pair (t¯t) spin correlations are presented using events containing two oppositely charged leptons (eþe−, eμ∓, or μþμ−) produced in proton-proton collisions at a center-of-mass energy of 13 TeV. The data were recorded by the CMS experiment at the LHC in 2016 and correspond to an in

Measurements of the production of the standard model Higgs boson decaying to a W boson pair are reported. The W+W− candidates are selected in events with an oppositely charged lepton pair, large missing transverse momentum, and various numbers of jets. To select Higgs bosons produced via vector boson fusion and associated production with a W or Z

A measurement of the top quark–antiquark pair production cross section σtt in proton–proton collisions at a centre-of-mass energy of 13 TeV is presented. The data correspond to an integrated luminosity of 35.9 fb−1, recorded by the CMS experiment at the CERN LHC in 2016. Dilepton events (e±μ∓, μ+μ−, e+e−) are selected and the cross

Measurements of the inclusive and differential production cross sections for the Higgs boson in the diphoton decay channel are performed using the data set of proton-proton collisions at 13 TeV collected by the CMS experiment at the LHC in 2016 and corresponding to an integrated luminosity of 35.9 fb(-1). The cross sections are measured in a fiduci

Exclusive ρ(770) 0 photoproduction is measured for the first time in ultraperipheral pPb collisions at √s NN = 5.02 TeV with the CMS detector. The cross section σ (γp → ρ(770) 0 p) is 11.0 ± 1.4 (stat) ± 1.0 (syst) μb at �Wγ p � = 92.6 GeV for photon–proton centre-of-mass energies Wγ p between 29 and 213 GeV. The differential cro

A top quark mass measurement is performed using 35.9fb-1 of LHC proton–proton collision data collected with the CMS detector at s=13TeV. The measurement uses the t t ¯ all-jets final state. A kinematic fit is performed to reconstruct the decay of the t t ¯ system and suppress the multijet background. Using the ideogram method, the top quark mas

A measurement of the energy density in proton– proton collisions at a centre-of-mass energy of √s = 13 TeV is presented. The data have been recorded with the CMS experiment at the LHC during low luminosity operations in 2015. The energy density is studied as a function of pseudorapidity in the ranges − 6.6 <η< − 5.2 and 3.15 <

Measurements of prompt ψ(2S) meson production cross sections in proton–lead (pPb) and proton–proton (pp) collisions at a nucleon–nucleon center-of-mass energy of √sNN = 5.02 TeV are reported. The results are based on pPb and pp data collected by the CMS experiment at the LHC, corresponding to integrated luminosities of 34.6 nb−1 and 28.0
