We report recent results on the dynamics of strange hadrons in two-body reactions relevant for near-threshold production in heavy-ion collisions at GSI/FAIR and NICA-Dubna. In particular, $bar K N$ scattering in hot and dense nuclear matter is studied within a chiral unitary framework in coupled channels, setting up the starting point for implementations in microscopic off-shell transport approaches. We focus on the calculation of transition rates with special attention to the excitation of hyperon resonances and isospin effects. Additionally, we explore unconventional strangeness generation by meson-meson and meson-baryon interactions in connection with recent HADES observations of deep sub-threshold $phi$ and $Xi$ production.
The challenges with the molecular model of the multiquark systems are the identification of the hadronic molecules and the interaction between two color neutral hadrons. We study the di-hadronic molecular systems with proposed interaction potential a
The one loop self energy of the neutral $rho$ meson is obtained for the effective $rhopipi$ and $rho NN$ interaction at finite temperature and density in the presence of a constant background magnetic field of arbitrary strength. In our approach, the
We investigate the hidden strange light baryon-meson system. With the resonating-group method, two bound states, $eta-N$ and $phi-N$, are found in the quark delocalization color screening model. Focusing on the $phi-N$ bound state around 1950,MeV, we
In-medium properties of the low-lying strange, charm, and bottom baryons in symmetric nuclear matter are studied in the quark-meson coupling (QMC) model. Results for the Lorentz-scalar effective masses, mean field potentials felt by the light quarks
In this article, we have explored the very important quantity of lepton pair production from a hot and dense QCD medium in presence of an arbitrary magnetic field for simultaneous nonzero values of both the parallel and perpendicular components of mo
