Quantifying the Underlying Event in High-energy pp Collisions from RHIC to LHC

Dr. Gergely Gábor Barnaföldi (Wiger Research Centre fpr Physics, Hungary)

We present a study of the transverse momentum spectra of charged hadrons and their evolution as a function of their azimuthal position with respect to the leading particle in proton\u2013proton collisions from RHIC to LHC energies using the PYTHIA8 Monte Carlo event generator with the Monash 2013 tune. The spherocity distribution in the same azimuthal bins is reported. The Multiplicity and midrapidity transverse momentum spectra of charged hadrons have been analysed in the non-extensive statistical framework. The results corresponding to the Underlying Event are reported. This work provides a possible understanding of the interplay between hard scatterings and the Underlying Event in proton\u2013proton collisions.
