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 …

Search for production of four top quarks in final states with same-sign or multiple leptons in proton–proton collisions at $$\sqrt{s}=13$$ $$\,\text {TeV}$$

A. M. Sirunyan, A. Tumasyan, W. Adam, F. Ambrogi et autres

Abstract The standard model (SM) production of four top quarks ( $$\text {t} {}{\overline{\text {t}}} \text {t} {}{\overline{\text {t}}} $$ tt¯tt¯ ) in proton–proton collisions is studied by the CMS Collaboration. The data sample, collected during the 2016–2018 data taking of the …

Evidence for $$\text {W}\text {W}$$ production from double-parton interactions in proton–proton collisions at $$\sqrt{s} = 13 \,\text {TeV} $$

A. M. Sirunyan, A. Tumasyan, W. Adam, F. Ambrogi et autres

Abstract A search for $$\text {W}\text {W}$$ WW production from double-parton scattering processes using same-charge electron-muon and dimuon events is reported, based on proton-proton collision data collected at a center-of-mass energy of $$13\,\text {TeV} $$ 13TeV . The analyzed data set corresponds …

Measurement of prompt and nonprompt charmonium suppression in $$\text {PbPb}$$ collisions at 5.02$$\,\text {Te}\text {V}$$

A. M. Sirunyan, A. Tumasyan, W. Adam, F. Ambrogi et autres

Abstract The nuclear modification factors of $${\mathrm {J}/\psi }$$ J / ψ and $$\psi \text {(2S)}$$ ψ (2S) mesons are measured in $$\text {PbPb}$$ PbPb collisions at a centre-of-mass energy per nucleon pair of $$\sqrt{\smash [b]{s_{_{\text {NN}}}}} = 5.02\,\text {Te}\text {V} $$ …
