Observation of the Charged-Particle Multiplicity Dependence of σψ(2S)/σJ/ψ in p -Pb Collisions at 8.16 TeV

Aram Hayrapetyan, В. Макаренко, A. Tumasyan, W. Adam et autres

Bound states of charm and anticharm quarks, known as charmonia, have a rich spectroscopic structure that can be used to probe the dynamics of hadron production in high-energy hadron collisions. Here, the cross section ratio of excited (ψ(2S)) and ground state (J/ψ) …

Measurement of W W Z and Z H Production Cross Sections at s = 13 and 13.6 TeV

В. Макаренко, A. Tumasyan, W. Adam, J W Andrejkovic et autres

A measurement is presented of the cross section in proton-proton collisions for the production of two W bosons and one Z boson. It is based on data recorded by the CMS experiment at the CERN LHC at center-of-mass energies sqrt[s]=13 and 13.6 …

Search for flavor changing neutral current interactions of the top quark in final states with a photon and additional jets in proton-proton collisions at s=13 TeV

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

A search for the production of a top quark in association with a photon and additional jets via flavor changing neutral current interactions is presented. The analysis uses proton-proton collision data recorded by the CMS detector at a center-of-mass energy of 13 …

Measurement of the Drell-Yan forward-backward asymmetry at high dilepton masses in proton-proton collisions at $$ \sqrt{s} $$ = 13 TeV

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

Abstract A measurement of the forward-backward asymmetry of pairs of oppositely charged leptons (dimuons and dielectrons) produced by the Drell-Yan process in proton-proton collisions is presented. The data sample corresponds to an integrated luminosity of 138 fb−1 collected with the CMS detector …

Search for heavy resonances decaying to Z(νν¯)V(qq¯′) in proton-proton collisions at s=13 TeV

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

A search is presented for heavy bosons decaying to $Z(\ensuremath{\nu}\overline{\ensuremath{\nu}})V(q{\overline{q}}^{\ensuremath{'}})$, where $V$ can be a $W$ or a $Z$ boson. A sample of proton-proton collision data at $\sqrt{s}=13\text{ }\text{ }\mathrm{TeV}$ was collected by the CMS experiment during 2016--2018. The data correspond to …

Correlations of azimuthal anisotropy Fourier harmonics with subevent cumulants in pPb collisions at sNN=8.16TeV

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

Event-by-event long-range correlations of azimuthal anisotropy Fourier coefficients $({v}_{n})$ in 8.16 TeV $p\mathrm{Pb}$ data, collected by the CMS experiment at the CERN Large Hadron Collider, are extracted using a subevent four-particle cumulant technique applied to very low multiplicity events. Each combination of …

Observation of electroweak production of Wγ with two jets in proton-proton collisions at s=13 TeV

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

A first observation is presented for the electroweak production of a W boson, a photon, and two jets in proton-proton collisions. The W boson decays are selected by requiring one identified electron or muon and an imbalance in transverse momentum. The two …

Investigation into the event-activity dependence of ϒ(nS) relative production in proton-proton collisions at $$ \sqrt{s} $$ = 7 TeV

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

Abstract The ratios of the production cross sections between the excited ϒ(2S) and ϒ(3S) mesons and the ϒ(1S) ground state, detected via their decay into two muons, are studied as a function of the number of charged particles in the event. The …
