Search for physics beyond the Standard Model in pp collisions at the CMS experiment with a signature of a Z boson plus missing transverse energy

of Dissertation The Standard Model of elementary particles is a theory that describes the fundamental structure of matter and interactions among the elementary particles. While the gravitational

A search for new physics in high-mass ditau events in the ATLAS detector

This thesis presents a review of work on the performance of the reconstruction and identification of hadronic tau decays and studies of events reconstructed with a lepton-hadron final state with the

Studies of the Higgs boson properties and search for new physics beyond the standard model in the top sector with the ATLAS detector

Proton-proton collisions at a center of mass energy of 13 TeV recorded during 2015-2017 with the ATLAS detector at LHC are analyzed in this thesis. The first part of the thesis details electron

Topics in chiral perturbation theory for charmed mesons

This thesis is concerned with topics in chiral perturbation theory for pseudoscalar charmed mesons in a manifestly Lorentz-invariant way. After constructing the chiral effective Lagrangian describing

Interference effects in new physics processes at the LHC

Interference effects between nearly mass-degenerate particles are ad- dressed in this thesis, comprising higher-order calculations, a model- independent method to calculate interference terms

Measurement of the associated production of a vector boson (W, Z) and top quark pair in the opposite sign dilepton channel with pp collisions at $\sqrt{s} = 8$ TeV with the ATLAS detector

The heaviest known elementary particle predicted by the Standard Model (SM), the top quark, was discovered in 1995 by the CDF and D0 collaborations. The large top quark mass translates into a

Precision Experiments at LEP

The Large Electron Positron Collider (LEP) established the Standard Model (SM) of particle physics with unprecedented precision, including all its radiative corrections. These led to predictions for

Studies of effective theories beyond the Standard Model

We investigate the possibility of contributions from physics beyond the Standard Model (SM) to the Higgs couplings, in the light of the LHC data. The work is performed within an interim framework

Higgs production in association with a Z Boson at the LHC

The associated Z vector boson production rate of the Standard Model Higgs boson has been measured in decays into two b quarks, with the Z boson decaying into an electron or muon pair in the

Determination of the top-quark pole mass using tt+1-jet events with the ATLAS detector at the LHC
