The production of K$^*$(892)$^\pm$ meson resonance is measured at midrapidity ($|y|<0.5$) in Pb-Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV using the ALICE detector at the LHC. The resonance is reconstructed via its hadronic decay channel K$^*$(892)$^\pm \rightarrow \rm{K^0_S \pi^\pm}$. [...]

Femtoscopic correlations of identical charged pions and kaons in pp collisions at \sqrt{s} = 13 TeV with event-shape selection

The ALICE Collaboration reports measurements of the semi-inclusive distribution of charged-particle jets recoiling from a high transverse momentum (high $p_\mathrm{T}$) charged hadron, in pp and central Pb--Pb collisions at center of mass energy per nucleon--nucleon collision $\sqrt{s_\mathrm{NN}}=5.02$ TeV. The large uncorrelated background in central Pb--Pb collisions is corrected using a data-driven statistical approach, which enables precise measurement of recoil jet distributions over a broad range in $p_\mathrm{T,ch jet}$ and jet resolution parameter $R$.

The two-particle momentum correlation functions between charm mesons (D$^{*\pm}$ and D$^{\pm}$) and charged light-flavor mesons ($\uppi^{\pm}$ and K$^{\pm}$) in all charge-combinations are measured for the first time by the ALICE Collaboration in high-multiplicity proton--proton collisions at a center-of-mass energy of $\sqrt(s)=13$ TeV. For DK and D$^*$K pairs, the experimental results are in agreement with theoretical predictions of the residual strong interaction based on quantum chromodynamics calculations on the lattice and chiral effective field theory.

CERN-LHC-ALICE. The production of the $\psi(2S)$ charmonium state was measured with ALICE in Pb--Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV, in the dimuon decay channel. [...]

The first measurements of $\mathrm{K^{*}(892)^{0}}$ resonance production as a function of charged-particle multiplicity in Xe$-$Xe collisions at $\sqrt{s_{\mathrm{NN}}}=$ 5.44 TeV and pp collisions at $\sqrt{s}=$ 5.02 TeV using the ALICE detector are presented. The resonance is reconstructed at midrapidity ($|y|< 0.5$) using the hadronic decay channel $\mathrm{K^{*0}} \rightarrow \mathrm{K^{\pm} \pi^{\mp}}$. [...]

Investigating the nature of the K$^*_0(700)$ state with $\pi^\pm$ K$^0_{\rm S}$ correlations at the LHC. -- The first measurements of femtoscopic correlations with the particle pair combinations $\pi^\pm$ K$^0_{\rm S}$ in pp collisions at $\sqrt{s}=13$ TeV at the Large Hadron Collider are reported by the ALICE experiment. [...]

The measurements of the inclusive J/$\psi$ yield at midrapidity ($\left | y \right | < 0.9$) and forward rapidity (2.5 $< y <$ 4) in Pb$-$Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV with the ALICE detector at the LHC are reported. The inclusive J/$\psi$ production yields and nuclear modification factors, $R_{\rm AA}$, are measured as a function of the collision centrality, J/$\psi$ transverse momentum ($p_{\rm T}$), and rapidity [...]

The pseudorapidity dependence of elliptic ($v_{2}$), triangular ($v_{3}$), and quadrangular ($v_{4}$) flow coefficients of charged particles measured in Pb-Pb collisions at a centre-of-mass energy per nucleon pair of $\sqrt{s_{\mathrm{NN}}}=5.02\,\mathrm{TeV}$ and in Xe-Xe collisions at $\sqrt{s_{\mathrm{NN}}}=5.44\,\mathrm{TeV}$ with ALICE at the LHC are presented. The measurements are performed in the pseudorapidity range $-3.5 < \eta < 5$ for various centrality intervals using two- and multi-particle cumulants with the subevent method [...]
