Description
Parallel session strangeness
The study of hypernuclei in relativistic ion collisions open new
opportunities for nuclear and particle physics. The main processes
leading to the production of hypernuclei in these reactions are
(1) the disintegration of large excited hyper-residues (target-
and projectile-like), and (2) the coalescence of hyperons with other
baryons into light clusters. We use the transport, coalescence...
The production and properties of $K^+$, $K^-$ and $\phi$ in cold nuclear matter generated in pion-nucleus reactions ($\pi^- + A$, $A = C, W$) at $p_{\pi^-}= 1.7$~GeV/c has been investigated with the HADES setup at SIS18/GSI.
Of particular interest is the $K^-$ absorption in nuclear matter which should be driven by strangeness exchange processes on one ($K^- N\rightarrow Y\pi$) or more nucleons...
The primary goal of relativistic heavy-ion collisions is to seek and characterize a new state of nuclear matter, called the quark-gluon plasma (QGP), where quarks and gluons are deconfined due to the high temperature and energy density achieved in such collisions. Measurements of invariant yield of strange hadrons can provide information about the particle production mechanism and transport...
The measurement of $\phi$ mesons provides a unique and complimentary method for exploring properties of the hot and dense medium created in the relativistic heavy ion collisions. It has a relatively small hadronic interaction cross section and is sensitive to the increase of strangeness (strangeness enhancement), a phenomenon associated with soft particles in bulk matter. Measurements in the...
We present new results on J/psi production in p-Pb collisions, using the data collected in 2016 by LHCb at 8 TeV nucleon-nucleon center-of-mass energy. The LHCb experiment has the unique property to study heavy-ion interactions in the forward region (pseudorapidity between 2 and 5) with a fully instrumented detector. Both forward and backward rapidities are covered thanks to the possibility of...
We study the $\Lambda_c/D$ ratio and $p/\phi$ at RHIC and LHC within a realistic implementation of coalescence model.
The evolution of the partonic stage is described by the relativistic Boltzmann equation tuned at a fixed shear-viscosity to entropy-density ratio $\eta/s$ and a realistic equation of state.
Such an approach recovers the universal features of the ideal hydrodynamics.
In a...
Quantum Chromodynamics predicts the occurrence of a phase transition from the hadronic matter to a plasma of deconfined quarks and gluons (Quark-Gluon Plasma) at extreme conditions of temperature and energy density. Ultrarelativistic heavy-ion collisions provide the means to study this phase of matter in the laboratory.
Strangeness production is a key tool to understand the properties of the...
The results on the production of strange and multi-strange hadrons ($K_{0}^{S}$, $\Lambda$, $\Xi$ and $\Omega$) measured with ALICE in Pb-Pb collisions at the top LHC energy of $\sqrt{s_{\rm NN}}~=~5.02~TeV$ are reported.
Thanks to its excellent tracking and particle identification capabilities, ALICE is able to measure weakly decaying particles through the topological reconstruction of the...
Identified particle spectra provide an important tool for understanding the particle production mechanism and the dynamical evolution of the medium created in relativistic heavy ion collisions. Studies involving strange and multi-strange hadrons, such as $K^0_S$, $\Lambda$, $\Xi^-$, and $\Omega^-$, carry additional information since there is no net strangeness content in the initial colliding...
