Exact conservation of quantum numbers B, S and Q in the statistical description of high energy collisions
High energy collisions are studied assuming that particles can be described by a hadron gas in thermal and chemical equilibrium. The exact conservation of baryon number, strangeness and charge are explicitly taken into account. For heavy ions the effect arising from the neutron surplus becomes …

Partonic rescatterings during jet fragmentation in the QCD vacuum
High energy collisions of small systems like Proton-Proton ($pp$) and Proton-Lead ($p$Pb) have demonstrated surprising evidence for the existence of collectivity where it had previously been thought not to occur. Specifically, the medium produced by these collisions at the Large Hadron Collider …

Measurement of strange hadron production and perspectives for the search of D0→ μ+μ− decay at LHCb
The study of V0 particles in pp collisions is important for the comprehension of soft processes involved in strange quark production. Baryon asymmetry, measured as the ⊼/Λ production ratio, is crucial to understand the mechanism with which the baryon number information of the initial state is …

Calculations on production reactions using the absorptive peripheral model
… angular distributions of resonances produced in high energy collisions. The peripheral model with absorption is used in the calculations; only two body meson induced reactions are treated. A comparison between the partial wave summation method~ which is used here, and the earlier impact parameter …

Photoproduction of p0 Mesons in Ultra-Peripheral D-AU Collisions at RHIC
The rho meson is copiously produced in high-energy collisions. Sometimes these oppositely directed beams of charged nuclei (ions) interact head-on resulting in a central collision. But often these nuclei narrowly miss each other and interact through electromagnetic fields. This phenomenon, known as …

Monte Carlo simulations using infrared improved DGLAP-CS theory.
… main quantities that we compared were the pt, energy fraction and rapidity distributions. We made these comparisons at √s=14 TeV, the highest LHC energies. Comparisons were also made for π⁺ production in pp → 2-jets + X at this energy. As expected, the IR-improved spectra were generally softer. …

Emergence, Formation and Dynamics of Hot QCD Matter
… In particular, the hot QCD matter produced in high energy collisions of heavy ions presents a unique challenge to theory and phenomenology due to the vast number of different phenomena that take place in such a collision, and even more so because it is an out-of-equilibrium process. In this …

Continuum breakdown assessment and state-based transport modeling for non-equilibrium hypersonic flows
… chemical non-equilibrium encountered in these high speed flows are multi-temperature computational fluid dynamics (CFD), direct simulation Monte Carlo (DSMC), and hybrid CFD/DSMC solvers that capitalize on the advantages of both methodologies. Improving the kinetics and transport models used in …
