Systematics of baryon spectra and mT scaling in p+p and Au+Au collisions at √sNN = 200 GeV

In heavy ion collisions at RHIC, strongly interacting matter is under investigation and many signals point to the formation of quark gluon plasma (QGP). To disentangle the QGP signals, it is also important to understand particle production in smaller collision systems like p + p and d + A collisions. The mT scaling of hadrons allow the extrapolation to unknown regions needed to obtain the cocktail of decay products from produced hadrons and to get hadron ratios for freeze out conditions. In an earlier study, we tested the mT scaling method to obtain the meson spectra from measured pion spectrum for p + p, d + Au and Au + Au systems at √sNN = 200 GeV
