On QGP Formation in pp Collisions at 7 TeV

Abstract

The possibility of QGP formation in central pp collisions at ultra-high collision energy is discussed. Centrality-dependent $\pt$-spectra and (pseudo)rapidity spectra of thermal photons (charged hadrons) from pp collisions at 7 TeV are presented (addressed). Minimal-bias $\pt$-spectrum of direct photons and charged hadrons is compared under the framework with and without hydrodynamical evolution process.
