Momentum Anisotropy, Chromo-Weibel Instability and QGP Phenomenology

The momentum-space anisotropy present during the space-time evolution of the hot QCD medium in heavy-ion collisions may lead to chromo-Weibel instability in the medium. This mechanism further lead to anomalous transport and substantially reduce the transport coefficients of the medium. In this context, we model the near (non)- equilibrium momentum distribution functions of the quasi-gluons and quasi-quarks (antiquarks) that encode such effects from the anisotropy and employ them to study the heavy-quark transport coefficient and thermal particle production (dilepton production), in the hot QCD medium. It is observed that momentum anisotropy plays crucial role in understanding the properties of the hot QCD medium.
