The Standard Model of particle physics describes the fundamental interactions other than
gravity between the elementary particles. The model has successfully achieved to describe …

The CMS Tracker is the largest Silicon detector ever built, covering 200 square meters and
providing an average of 14 high-precision measurements per track. Track reconstruction is …

In this thesis the measurement of production cross section of top-quark pairs in association
with a photon in proton-proton collisions at a center of mass energy of 8 TeV is presented …

This thesis documents the measurement of lifetime, width, mass, and couplings to two
electroweak bosons of the recently-discovered Higgs boson using data from the CMS …

On 23 November 2009, the Large Hadron Collider (LHC) produced the first proton-proton
collisions and finally entered the “physics era”, after over twenty years of construction and …

Charged particle tracks and track-based higher level observables are a key ingredient of the
event reconstruction for the CMS experiment. In 2017, the CMS pixel detector was …

I present my work at the CMS experiment on a search for the standard model (SM) Higgs
boson produced in association with top quarks. The search is targeted towards final states …

This thesis describes the search for a new heavy boson decaying to a pair of heavy
electroweak bosons (WW, WZ, or WH) in the semileptonic final state (electron or muon …

Research and technical communities for optics, photonics and optoelectronics is grouped in
this country in several organizations and institutions. These are: Photonics Society of Poland …

This thesis presents measurements of multi-differential top quark pair (ttbar) production
cross-sections in pp collisions at the LHC with a center-of-mass energy of 13TeV using …
