Modeling polarization in AuAu collisions at GeV using relativistic spin hydrodynamics
Matteo Buzzegoli, Aleksandar Gecic, Rajeev Singh
We investigate spin polarization dynamics in relativistic heavy-ion collisions using ideal relativistic spin hydrodynamics, employing non-boost-invariant longitudinal solutions as…
Kubo formulas for spin polarization in dissipative relativistic spin hydrodynamics: a first-order gradient expansion approach
Matteo Buzzegoli
We use linear response theory to derive both the non-dissipative and dissipative effects of spin polarization for massive and massless interacting spin 1/2 particles in a relativis…
Spin polarization in heavy-ion collisions induced by thermal vorticity and thermal shear
M. Buzzegoli
The vorticity is a quantity defined in a relativistic fluid that describes how much a fluid element is rotating and accelerating. By measuring the spin polarization of hadrons, it…
Spin polarization in relativistic heavy-ion collisions
Francesco Becattini, Matteo Buzzegoli, Takafumi Niida +3
Polarization has opened a new physics chapter in relativistic heavy-ion collisions. Since the first prediction and experimental observation of global spin polarization, a lot of pr…
Spin polarization induced by magnetic field and the relativistic Barnett effect
Matteo Buzzegoli
First, I study the analogy between the magnetization of a material and the spin polarization of particles in a fluid. Using the relativistic version of the Barnett effect, i.e. the…
Polarization in heavy ion collisions: a theoretical review
Matteo Buzzegoli
In these proceedings I discuss the recent progress in the theory of spin polarization in relativistic fluids. To date, a number of studies have begun to examine the impact of the s…
Bound states and electromagnetic radiation of relativistically rotating cylindrical wells
Matteo Buzzegoli, Kirill Tuchin
We compute the effect of rigid rotation on the non-relativistic bound states. The energy levels of the bound states increase with the angular velocity of rotation until at certain…
Local equilibrium and Lambda polarization in high energy heavy ion collisions
Andrea Palermo, Francesco Becattini, Matteo Buzzegoli +2
The polarization of the hyperon has become an important probe of the Quark-Gluon Plasma produced in relativistic heavy-ion collisions. Recently, it has been found that polariza…
Spin-thermal shear coupling in relativistic nuclear collisions
M. Buzzegoli, F. Becattini, G. Inghirami +2
The spin polarization measurements of particles emitted in heavy-ion collisions have opened the possibility for new phenomenological investigations of spin physics in relativistic…
Pseudogauge dependence of the spin polarization and of the axial vortical effect
M. Buzzegoli
The mean spin polarization vector of spin 1/2 particles in a relativistic fluid at local thermal equilibrium (LTE) in different pseudogauges (PGs), i.e., with different choices for…
Local polarization and isothermal local equilibrium in relativistic heavy ion collisions
F. Becattini, M. Buzzegoli, G. Inghirami +2
We show that the inclusion of a recently found additional term of the spin polarization vector at local equilibrium which is linear in the symmetrized gradients of the velocity fie…
Spin-thermal shear coupling in a relativistic fluid
F. Becattini, M. Buzzegoli, A. Palermo
We show that spin polarization of a fermion in a relativistic fluid at local thermodynamic equilibrium can be generated by the symmetric derivative of the four-temperature vector,…
