Partonic differential cross section of muon pair hadroproduction in the Standard Model

Abstract

The partonic differential cross section of a muon pair hadroproduction was calculated using Feynman rules in the Standard Model. The production resulted from the collision of two hadrons (e.g. proton-proton). In calculating the muon pair hadroproduction differential cross section, we retained only two tree-level Feynman Diagrams: one with the virtual photon and the other with the virtual neutral Z⁰ boson. The calculated analytical expression was subjected into the high energy limit and expressed in Mandelstam variables, then compared to the differential cross section of the Drell-Yan process (pair production through photon) to observe the effect of the additional term contributed by the Z⁰ boson.
