Abstract

This thesis explores the relationship between matter and anti-matter through flavour physics observed in e+ e- collisions at the BESIII experiment and p p collisions at the LHCb experiment. The relationship between D0 and anti-D0 mesons as understood at the BESIII experiment is used to measure the parameter, gamma, arising from the Unitarity Triangle from the Cabibbo-Kobyashi-Maskawa (CKM) matrix, that describes the mixing of quarks in the Standard Model. We propose a novel method to measure the relative strong phase between D0 to KS0 pi+ pi- and anti-D0 to KS0 pi+ pi- towards achieving greater precision in measurements of gamma from B+- to D(to KS0 pi+ pi-) K+- decays. The BESIII experiment has the greatest precision in measurements of the relative strong phase between D0 to KS0 pi+ pi- and anti-D0 to KS0 pi+ pi- decays, whilst the LHCb experiment has the greatest precision in measurements of gamma from B+- to D(to KS0 pi+ pi-)K+- decays, thus the two measurements and two experiments complement each other.
