Combination of vector boson scattering measurements in leptonic final states in proton-proton collisions at $ \sqrt{s} = $ 13 TeV

Arzunik Gevorgyan, Aram Hayrapetyan, Vladimir Makarenko, Armen Tumasyan et autres

A statistical combination of vector boson scattering measurements in proton-proton collisions at $ \sqrt{s} = $ 13 TeV is presented. The analysis is based on a dataset corresponding to an integrated luminosity of 138 fb$ ^{-1} $, collected with the CMS detector …

Exploring the origin of $ \mathrm{D^0} $ meson elliptic flow in PbPb collisions at $ \sqrt{\smash[b]{s_{_{\mathrm{NN}}}}}= $ 5.02 TeV using event shape engineering

Arzunik Gevorgyan, Aram Hayrapetyan, Vladimir Makarenko, Armen Tumasyan et autres

The influence of the initial-state geometry on the elliptic flow of prompt $ \mathrm{D^0} $ mesons in high-energy heavy ion collisions is explored. A lead-lead (PbPb) data sample at a center-of-mass energy per nucleon pair of 5.02 TeV and with an integrated …

Evidence for sequential $ \Upsilon{\textrm{(nS)}} $ suppression in light ion collisions

Andrey Belyaev, Arzunik Gevorgyan, Aram Hayrapetyan, Armen Tumasyan et autres

Bound states of heavy quark-antiquark pairs, known as quarkonia, have long been regarded as particularly sensitive probes of the quark-gluon plasma (QGP). Comparing quarkonium yields in collisions of heavy nuclei, such as gold or lead, with a proton-proton (pp) reference reveals a …

Measurement of the $ \gamma\gamma \to \tau^{+}\tau^{-} $ cross section and constraints on the anomalous magnetic moment of the $ \tau $ lepton in ultraperipheral PbPb collisions at $ \sqrt{\smash[b]{s_{_{\mathrm{NN}}}}} = $ 5.02 TeV

The production of $ \tau $ lepton pairs via photon-photon fusion, $ \gamma\gamma \to \tau^{+}\tau^{-} $, is studied in ultraperipheral lead-lead collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV. The dataset, collected by the CMS experiment in 2018, corresponds to an …

Study of $ \chi_{c} $ production in $ \mathrm{p}\mathrm{Pb} $ collisions at $ \sqrt{s_{\mathrm{NN}}}= $ 8.16 TeV

Production of prompt P-wave charmonium states $ {\chi}_{c1} $(1P) and $ {\chi}_{c2} $(1P) is studied in proton-lead (pPb) collisions at a center-of-mass energy per nucleon pair of $ \sqrt{\smash[b]{s_{_{\mathrm{NN}}}}} = $ 8.16 TeV. The analysis is based on data corresponding to an …

Study of ZZ and ZH production in the $ \mathrm{b}\mathrm{b}\tau\tau $ final state and search for high-mass spin-0 and spin-1 resonances in proton-proton collisions at $ \sqrt{s}= $ 13 TeV

Arzunik Gevorgyan, Aram Hayrapetyan, Vladimir Makarenko, Armen Tumasyan et autres

A study of the production of pairs of Z bosons (ZZ) and of the associated production of a Z boson and a Higgs boson (ZH) in final states containing two b quarks and two tau leptons ($ \mathrm{b}\mathrm{b}\tau\tau $) is presented. The …

Measurement of the top quark pair production cross section in $ \mathrm{Pb}\mathrm{Pb} $ collisions at$ \sqrt{\smash[b]{s_{_{\mathrm{NN}}}}}= $ 5.36 TeV

Andrey Belyaev, Arzunik Gevorgyan, Aram Hayrapetyan, Armen Tumasyan et autres

The inclusive cross section for top quark pair ( $ \mathrm{t} \overline{\mathrm{t}} $) production in lead-lead ($ \mathrm{Pb}\mathrm{Pb} $) collisions is reported for the first time at a center-of-mass energy per nucleon pair of 5.36 TeV. The analysis uses data corresponding to …

Search for Higgs boson pair production in the $ \mathrm{b}\overline{\mathrm{b}}\mathrm{W}\mathrm{W} $ decay channel with two leptons in the final state using proton-proton collision data at $ \sqrt{s}= $ 13.6 TeV

Arzunik Gevorgyan, Aram Hayrapetyan, В. Макаренко, A. Tumasyan et autres

A search for Higgs boson pair production is presented, targeting final states where one Higgs boson decays to a pair of bottom quarks and the other Higgs boson decays to two W bosons, both of which decay leptonically, to an electron or …
