| Vienna Theory Lunch Club - Yoctosecond light flashes from heavy ion collisions |
| Speaker: | Andreas Ipp (TU Vienna) |
| Abstract: | Collisions of heavy ions in particle accelerators like RHIC and soon LHC can produce the quark-gluon plasma, a new state of matter at ultra-hot temperatures, for the time of a few yoctoseconds. Besides many particles that are produced in such collisions, also high-energy photons are emitted from the plasma. We focus on photons produced in the plasma through Compton scattering of gluons and quark-antiquark annihilation. Looking at the time-evolution of the photon emission for the anisotropically expanding plasma, we find under certain conditions double pulses at the yoctosecond time scale. Such double pulses may be utilized in the future for novel pump-probe experiments at nuclear time scales.
