Heavy quark polarization anisotropy as a novel probe of fireball geometry

Amaresh Jaiswal

We propose a new approach to probe the initial fireball geometry in relativistic heavy-ion collisions using spin polarization. Specifically, we introduce polarization harmonics of…

Spin dynamics and polarization in relativistic systems: recent developments

Sourav Dey, Arpan Das, Hiranmaya Mishra +1

We review recent theoretical and experimental developments in spin dynamics and polarization phenomena in relativistic systems, with a particular focus on heavy-ion collisions. The…

Quantum spin dynamics of heavy quarks and polarization observables in relativistic heavy-ion collisions

Sunil Jaiswal, Sourav Dey, Amaresh Jaiswal

We develop a quantum spin-density-matrix framework for heavy-quark spin dynamics in relativistic heavy-ion collisions. Starting from an initial polarization induced along the magne…

Dissipative spin hydrodynamics in Bjorken flow and thermal dilepton production

Sejal Singh, Sourav Dey, Arpan Das +2

We investigate the boost-invariant expansion of a recently developed first-order spin hydrodynamic framework in which the spin chemical potential is treated as a leading-order hydr…

Polarized tau decay and CP violation in ultraperipheral heavy-ion collisions

Amaresh Jaiswal

We investigate the role of -lepton polarization in ultraperipheral heavy-ion collisions (UPCs) as a novel application of the intense electromagnetic fields generated in such pr…

Hyperon longitudinal polarization and vector meson spin alignment in a thermal model for heavy-ion collisions

Soham Banerjee, Samapan Bhadury, Wojciech Florkowski +2

The concept of a common local spin equilibrium for both spin-1/2 and spin-1 particles is incorporated into a thermal model of particle production in heavy-ion collisions at the top…
