The system created in semi-central heavy ion collisions behaves like a fluid with a large orbital angular momenta, resulting in a great vorticity. Due the spin-orbit coupling we expect that particles produced in such collisions, acquire polarization in the direction of the orbital angular momenta of the system, and that the induced polarization be the same for particles and antiparticles. However ... More

In this work, the photon production at the early stages of a heavy-ion collision is computed by taking into account the magnetic field effects on a magnetized glasma. In particular, the gluon fusion and gluon splitting channels are considered. The magnetic field effect is given in terms of the internal quark lines through the fermion propagator expressed in Landau levels. Moreover, the dependence ... More

The polarization of $\Lambda$ hyperons is self-analyzed in their weak decays and represents a sensitive tool to explore the dynamics of hadronic reactions and heavy-ion collisions. It was extensively studied in hadronic reactions, where it is directed along the normal to the scattering plane. In heavy-ion collisions this observable is expected to decrease due to randomization of the scattering on ... More

The essential ingredients of QCD description of spin asymmetries in hadronic and heavy-ion collisions are reviewed and compared. The parity conserving QCD Lagrangian implies the orientation of spin pseudovector along the normal to scattering or reaction plane. The role of axial anomaly in producing the spin-orbital coupling is discussed. The imaginary phases due to higher twist in hadronic colli ... More

Experiments that collide heavy nuclei at high energies have proven to be incredibly useful to study matter at its fundamental level. One of the most striking features of matter in heavy-ion collisions is that it forms the most perfect fluid that we know of and, consequently, can be described using the methods of hydrodynamics. Within this framework, the study of the thermal vorticity can lead to ... More
