Transverse angular distributions of Drell-Yan dilepton pairs from 8.6 fb^-1 of p\bar{p} collisions at \sqrt{s} = 1.96 TeV at D0

Abstract

The angular distributions of leptons from the decays of Drell-Yan dilepton pairs are studied in 8.6 fb^-1 of p\bar{p}collisions recorded with theD0 detector at the Fermilab Tevatron collider. Drell-Yan events are often analysed in the Collins-Soper reference frame, which defines two angles, phi_cs and theta_cs, in the planes transverse to and along the beam direction respectively. The shape of the phi_cs distribution is measured in bins of the dilepton transverse momentum, using events in the ee and mu mu decay channels. Predictions from the Monte Carlo program PYTHIA are in good agreement with the data.Name: John BeddowUniversity of Manchester, School of Physics and AstronomyDegree: Master of ScienceTitle: Transverse angular distributions of Drell-Yan dilepton pairs from 8.6 fb^-1 of p bar{p} collisions at sqrt{s} =$~1.96 TeV at D0Date: February 2012
