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

Arzunik Gevorgyan, Aram Hayrapetyan, Vladimir Makarenko, A. Tumasyan et autres

The influence of the initial-state geometry on the elliptic flow of prompt 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 luminosity of …

Study of $χ_{\mathrm{c}}$ production in pPb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 8.16 TeV

A. Belyaev, Aram Hayrapetyan, A. Tumasyan, Wolfgang Adam et autres

Production of prompt P-wave charmonium states $χ_\mathrm{c1}$(1P) and $χ_\mathrm{c2}$(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 integrated luminosity of 175 nb$^{-1}$ collected …

Measurement of the $γγ\to ττ$ cross section and constraints on the anomalous magnetic moment of the $τ$ lepton in ultraperipheral PbPb collisions at $\sqrt{s_\mathrm{NN}}$ = 5.02 TeV

A. Belyaev, Aram Hayrapetyan, A. Tumasyan, Wolfgang Adam et autres

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 integrated luminosity of …
