First measurement of jet axis decorrelation with photon-tagged jets in pp and $ \mathrm{PbPb} $ collisions at 5.02 TeV

Aram Hayrapetyan, Armen Tumasyan, Wolfgang Adam, Janik Walter Andrejkovic et autres

The first measurement of the jet axis decorrelation in events with jets recoiling from an isolated photon is presented for lead-lead ($ \mathrm{PbPb} $) and proton-proton (pp) collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV. The jet axis decorrelation is the …

Influence of strangeness on the anisotropic flow of prompt $ \mathrm{D}_{s}^{\pm} $ mesons in PbPb collisions at $ \sqrt{\smash[b]{s_{_{\mathrm{NN}}}}} = $ 5.02 TeV

Andrey Belyaev, Aram Hayrapetyan, Armen Tumasyan, Wolfgang Adam et autres

The azimuthal anisotropy of prompt $ \mathrm{D}_{s}^{\pm} $ mesons produced in lead-lead (PbPb) collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV is measured using data obtained with the CMS detector. The dataset corresponds to an integrated luminosity of 0.58$ \text{nb}^{-1}$. The …
