This thesis present studies of photon or Z plus two jet events produced with strong and electroweak interactions in proton-proton collisions at 13 TeV center of mass energy.

In this work the distribution of data/MC comparison with different generators will be shown. The signal can be established based on the fit to a multivariate discriminator, in two independent data samples according to their trigger paths, with the medium photon transverse momentum ,75 < PT< 200 GeV , and large photon transverse momentum PT >200 GeV.

Abstract

This thesis present studies of photon or Z plus two jet events produced with strong and electroweak interactions in proton-proton collisions at 13 TeV center of mass energy. Events with a photon or Z and a pair of jets with a large dijet invariant mass, are selected. This thesis makes use of data collected by CMS detector, in 2016, 2017 and 2018 with integrated luminosities of 35.9 f/b, 41.4 f/b and 59.73 f/b, respectively. In this work the distribution of data/MC comparison with different generators will be shown. The signal can be established based on the fit to a multivariate discriminator, in two independent data samples according to their trigger paths, with the medium photon transverse momentum ,75 < PT< 200 GeV , and large photon transverse momentum PT >200 GeV.
