Multiplicity dependence of ϒ production at forward rapidity in pp collisions at $\sqrt{s}$ = 13 TeV

Shreyasi Acharya, Dagmar Adamova, A. Akindinov, Jana Bielcikova et autres

The measurement of ϒ(1S), ϒ(2S), and ϒ(3S) yields as a function of the charged-particle multiplicity density, dNch/dη, using the ALICE experiment at the LHC, is reported in pp collisions at $\sqrt{s}$ = 13 TeV. The ϒ meson yields are measured at forward …

Dielectron production in central Pb-Pb collisions at $\sqrt{s_{NN}}$ = 5.02TeV

S. Acharya, Dagmar Adamova, Mohammad Al-turany, Jana Bielcikova et autres

The first measurement of the e$^+$e$^−$ pair production at midrapidity and low invariant mass in central Pb-Pb collisions at $\sqrt{s_{NN}}$=5.02TeV at the Large Hadron Collider is presented. The yield of e$^+$e$^−$ pairs is compared with a cocktail of expected hadronic decay contributions …

Skewness and kurtosis of mean transverse momentum fluctuations at the LHC energies

S. Acharya, D. Adamová, G. Aglieri Rinella, M. Agnello et autres

The first measurements of skewness and kurtosis of mean transverse momentum (〈$p_T$〉) fluctuations are reported in Pb–Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV, Xe–Xe collisions at $\sqrt{s_{NN}}$ = 5.44 TeV and pp collisions at $\sqrt{s}$=5.02 TeV using the ALICE detector. The measurements …

First polarisation measurement of coherently photoproduced $J/ψ$ in ultra-peripheral Pb–Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV

Shreyasi Acharya, D. Adamová, Alexander Adler, Gianluca Aglieri Rinella et autres

The first measurement of the polarisation of coherently photoproduced $J/ψ$ mesons in ultra-peripheral Pb–Pb collisions, using data at $\sqrt{s_{NN}}$ = 5.02 TeV, is presented. The $J/ψ$ meson is measured via its dimuon decay channel in the forward rapidity interval −4.0 < $y$ …

Study of the p$-$p$-$K$^+$ and p$-$p$-$K$^-$ dynamics using the femtoscopy technique

S. Acharya, D. Adamová, Alexander Adler, Gianluca Aglieri Rinella et autres

The interactions of kaons (K) and antikaons ($\mathrm{\overline{K}}$) with few nucleons (N) were studied so far using kaonic atom data and measurements of kaon production and interaction yields in nuclei. Some details of the three-body KNN and $\mathrm{\overline{K}}$NN dynamics are still not …
