The Phenomenology of Yoctosecond Pulses from a Quark-Gluon Plasma

Speaker:	Peter Somkuti (TU Wien)
Abstract:	A quark-gluon plasma formed in heavy-ion collision experiments may feature initial momentum-space anisotropies. Such an anisotropic QGP exhibits a direct photon spectrum which is strongly dependent on the emission angle. Using models for the time evolution of the plasma, a time-dependent photon signal can be calculated whose length is on the order of yoctoseconds. Placing a detector at lower angles close to the beam axis, a photon signal shows a remarkable double-peak shape. In this talk, I will explain the mechanisms that give rise to double pulses, how the effect of such pulses could be observed, and what these pulses can tell us about the quark-gluon plasma itself.
