Measurement of the top quark mass using a profile likelihood approach with the lepton + jets final states in proton–proton collisions at $$\sqrt{s}=13\,\text {Te}\hspace{-.08em}\text {V} $$

A. Tumasyan, W. Adam, Janik Walter Andrejkovic, T. Bergauer et autres

Abstract The mass of the top quark is measured in 36.3 $$\,\text {fb}^{-1}$$ fb - 1 of LHC proton–proton collision data collected with the CMS detector at $$\sqrt{s}=13\,\text {Te}\hspace{-.08em}\text {V} $$ s = 13 Te V . The measurement uses a sample …

Observation of the Rare Decay of the η Meson to Four Muons

Aram Hayrapetyan, A. Tumasyan, W. Adam, Janik Walter Andrejkovic et autres

A search for the rare $\ensuremath{\eta}\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$ double-Dalitz decay is performed using a sample of proton-proton collisions, collected by the CMS experiment at the CERN LHC with high-rate muon triggers during 2017 and 2018 and corresponding to an integrated luminosity of $101\text{ }\text{ …

Measurement of the Higgs boson inclusive and differential fiducial production cross sections in the diphoton decay channel with pp collisions at $$ \sqrt{s} $$ = 13 TeV

A. Tumasyan, W. Adam, Janik Walter Andrejkovic, T. Bergauer et autres

Abstract The measurements of the inclusive and differential fiducial cross sections of the Higgs boson decaying to a pair of photons are presented. The analysis is performed using proton-proton collisions data recorded with the CMS detector at the LHC at a centre-of-mass …

Search for medium effects using jets from bottom quarks in PbPb collisions at $\sqrt{sNN}$ =5.02 TeV

A. Tumasyan, W. Adam, J. W. Andrejkovic, T. Bergauer et autres

The first study of the shapes of jets arising from bottom (b) quarks in heavy ion collisions is presented. Jet shapes are studied using charged hadron constituents as a function of their radial distance from the jet axis. Lead-lead (PbPb) collision data …
