The coherent description of nuclear matter properties at high baryon densities is of utmost importance. The limited number of experimental references in the region of the phase diagram corresponding to Neutron Stars (NS) and NS mergers poses major challenges for constructing a universal Equation of State. The matter created in heavy-ion collisions at the HADES experiment can be characterized...
We train a deep convolutional neural network to predict hydrodynamic results for flow coefficients, average $p_T$ and charged particle multiplicities in ultrarelativistic heavy-ion collisions from the initial energy density profiles event-by-event [1]. We show that the network can be trained accurately enough so that it can reliably predict the hydrodynamic results for the flow coefficients...
We present measurements of two-particle angular correlations of charged particles emitted in high-energy $e^+e^-$ collisions using data collected by the ALEPH detector at LEP between 1992 and 2000. The correlation functions are measured over a wide range of pseudorapidity and azimuthal angle as a function of charged particle multiplicity. Previous measurement with LEP1 data at $\sqrt{s}=91$...
Hypernuclei are bound states of nuclei with one or more hyperons. Precise measurements of hypernuclei properties and their production yields in heavy-ion collisions are crucial for the understanding of their production mechanisms. The strangeness population factor, $S_{\rm A}=(^{A}_{\Lambda}\mathrm{H}/^{A}\mathrm{He})/(\Lambda/p)$ (A=3,4), is directly related to the ratio of light nuclei and...
Measurements of dijets that traverse a quark-gluon plasma can provide insights into the jet energy loss in heavy ion collisions. Furthermore, considering jets of various sizes can help elucidate how the parton energy is transferred to the medium as well as the medium response. Measurements of the dijet momentum imbalance and nuclear modification factors for leading and subleading jet pairs...
Nowadays, relativistic dissipative hydrodynamics including effects of finite viscosities is commonly used to extract transport properties of the quark gluon plasma (QGP), such as shear viscosity and bulk viscosity, from experimental data. However, according to the fluctuation-dissipation relation (FDR) in non-equilibrium statistical physics, fluctuations and dissipation are always accompanied...
Investigating particle production in small systems has become instrumental
in probing non-perturbative contributions to hadron structure and hadroniza-
tion mechanisms. The LHCb spectrometer unique geometry at the LHC along
with its particle identification and tracking capabilities allow for new studies
of the multiplicity-dependent enhancement of strange hadrons in the forward
region....
Understanding the strong interaction between nucleons and hyperons is fundamental for the microscopic description of bound systems as well as for modeling the equation of the state of dense stellar objects, such as neutron stars. Conventional scattering and hypernuclei measurements are insufficient to support theoretical predictions about the interaction between hadrons containing strangeness....
One of the most prominent features of the quark gluon plasma is its near-perfect
fluid behavior. An important outstanding question is establishing the degree to which
heavy flavor particles flow with the bulk system. Measurements of the Fourier coefficient
v2 of light and heavy flavor hadrons can provide insight into the properties of the
medium. At low transverse momentum (pT) the mass...
The sPHENIX project is a new detector experiment at the Relativistic Heavy Ion Collider at BNL. Its aim is to study strongly interacting Quark-Gluon Plasma and cold-QCD by measuring photons, jets, jet correlations, and Upsilon family with high precision. To achieve these goals, a precise tracking system is necessary. The tracking system of the sPHENIX detector consists of the MVTX, TPC, TPOT,...
