High $p_{T}$ inclusive hadron and photon spectra in pp and PbPb collisions
Abstract
In this article, we report the inclusive charged hadron and isolated photon spectra at TeV PbPb collisions measured with the CMS detector at LHC. Charged particle momentum spectra are compared to a constructed reference measurement of proton-proton collisions at TeV by using a combination of scaling and direct interpolation at fixed . Photon results are compared to next to leading order calculations at the same center of mass energy. Nuclear modification factors () are calculated to study the properties of the medium. While a large suppression is observed in the charged particle at high transverse momentum, isolated photons show no modifications, revealing that PbPb collisions at TeV produce a strongly interacting colored medium.
