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…
