description | In this thesis the search of dark matter is described by analyzing the transverse
mass spectrum of proton-proton collisions events with one muon and missing transverse
energy in the final state. Dark matter produced in the annihilation of two quarks is
investigated. For this, three simplifiied models based on a mediator particle are used:
axial vector, scalar and pseudoscalar. It is assumed that dark matter particles are
weakly interacting massive particles. The search of this kind of matter is one of the
main purposes of Large Hadron Collider. In this thesis we are using the data collected
by the Compact Muon Solenoid during the Run II in 2015 with a center of mass energy
of 13 TeV and integrated luminosity of 2.3 fb-1.
As no significant deviation from the Standard Model predictions is seen, exclusion
limits at 95% CL for the model parameters can be set. The sensitivity of this study is
presented in terms of excluded mediator and dark matter masses for the models. |
