   $K^{\ast }(892)$ and $\varphi (1020)$ production and their decay into the hadronic medium at the Large Hadron Collider

   V. M. Shapoval🇺🇦 · P. Braun-Munzinger🇩🇪 · Yu. M. Sinyukov🇺🇦

   The production of the $K^{\ast }(892)$ strange resonance in Pb+Pb collisions at $\sqrt{s_{NN}}=2.76$ TeV LHC energy is analyzed within the integrated hydrokinetic model (iHKM) at different equations of state of superdense matter. The similar analysis is done also for the RHIC top energy $\sqrt{s_{NN}}=200$ GeV for comparison purposes. A modification of experimental $K^{\ast }(892)$-identification is studied for different centralities in view of possible re-scattering of the decay products at the afterburner stage of the fireball evolution. We see quite intensive rescattering of the decay products as well as recombination processes for $K^{\ast }(892)$. In addition, the production of the much longer-long-lived $\varphi (1020)$ resonance with hidden strange quark content is investigated.

   DPS in CGC: Double Quark Production and Effects of Quantum Statistics

   Alex Kovner🇺🇸 · Amir H. Rezaeian🇨🇱

   We consider forward inclusive production of two quarks in the high energy p-A collisions in the CGC formalism. We demonstrate that the production cross-section is determined by the convolution of the proton generalized double transverse momentum-dependent distribution (2GTMD) functions with two independent eikonal scattering amplitudes: the product of two dipoles and a quadrupole. We explicitly demonstrate that the quadrupole amplitude term accounts for all the (initial and final state) effects of quantum statistics for identical fermions, and the correlations due to these effects. We also demonstrate that the effects due to quantum statistics (entirely encoded in the quadrupole) are parametrically leading contributions to the correlated particle production at large $N_c$. For non-identical quarks the quadrupole term also leads to correlated production which has characteristics similar to the HBT effect.
