Description

The quark-gluon plasma at the early stage of relativistic heavy-ion collisions is strongly anisotropic. We systematically study spectrum of collective excitations of such a plasma which is a fundamental characteristic of any many-body system. We demonstrate how the spectrum evolves when the momentum distribution of plasma constituents changes from the extremely prolate – infinitely elongated along the beam direction, through the isotropic one to the extremely oblate – infinitely squeezed in the beam direction. We discuss when unstable modes show up and when they disappear; their role in the plasma dynamics is also considered.
