Somkuti, P. (2011). Modifications of spectra and correlations through yoctosecond photon double pulses from a quark-gluon plasma [Diploma Thesis, Technische Universität Wien]. reposiTUm. https://resolver.obvsg.at/urn:nbn:at:at-ubtuw:1-59540
We calculate Hanbury Brown - Twiss (HBT) correlation functions as well as direct photon spectra from an anisotropic quark-gluon plasma (QGP) in order to investigate possible indirect signals of photon double pulses on the yoctosecond timescale, which arise at low emission angles.<br />Both quantities show a dependence on the isotropization time of the QGP.<br />We find that HBT correlations exhibit non-trivial features, such as plateaus or a second peak. The ratio of two spectra measured at different emission angles is especially sensitive to early isotropization times.
