Chemical potential differentials in the QCD phase diagram from heavy-ion isobar collisions

Joaquin Grefa, Chun Yue Tsang, Rajesh Kumar +3

Temperature and baryon, charge, and strangeness chemical potentials characterize QCD matter under extreme conditions. Differences between these chemical potentials and their ratios…

Exploring the role of hexaquarks on quark deconfinement and hybrid stars

Marcos O. Celi, Mauro Mariani, Rajesh Kumar +5

We investigate the impact of the (2380) hexaquark on the equation of state (EoS) of dense matter within hybrid stars (HSs) using the Chiral Mean-Field model (CMF). The hexaqua…

Neutron stars and Constraints for the Equation of State of Dense Matter

Rajesh Kumar, Veronica Dexheimer, Johannes Jahan

Neutron stars provide a natural laboratory for studying the properties of dense nuclear matter under extreme conditions. In this proceeding, we review our current understanding of…

Modern nuclear and astrophysical constraints of dense matter in a renormalized chiral approach

Rajesh Kumar, Yuhan Wang, Nikolas Cruz Camacho +3

We explore the Quantum Chromodynamics (QCD) phase diagram's complexities, including quark deconfinement transitions, liquid-gas phase changes, and critical points, using the chiral…

Interacting mesons as degrees of freedom in a chiral model

Rajesh Kumar, Joaquin Grefa, Konstantin Maslov +5

We study the equation of state of hot and dense hadronic matter using an extended Chiral Mean Field (CMF) model framework where the addition is the inclusion of interactions of the…
