Diboson physics with CMS detector
In this dissertation, you will find a study of di-boson production in pp collision with the Compact Muon Solenoid (CMS) detector at Large Hadron Collider (LHC). A study of Z+gamma process is performed on the data collected by the CMS during 2011 and corresponding to integrated luminosity L= 5 …

Searches for Diboson New Physics and the L1Calo Software Development with the ATLAS Detector
… is presenting the searches for new physics with diboson signatures in these two ways from LHC $\sqrt{s}=13~TeV$ collisions with the ATLAS detector with the data collected in 2015 and 2016 corresponding to an integrated luminosity of $36.1~fb^{-1}$. The searching strategy was performed with the …

Search for Diboson resonances in 8 tev and 13 tev proton-proton collisions at the large hadron collider with the atlas detector
This thesis documents two searches for Diboson Resonances which were performed using data collected in 2012, 2015 and 2016 by the ATLAS detector at the Large Hadron Collider. Three benchmark models are tested: a model predicting the existence of a new heavy scalar singlet, a simplified model …

Search for Excited Randall-Sundrum Gravitons with Semi-Leptonic Diboson Final States in 4.7 fb-1 of Proton-Proton Collisions using the ATLAS Detector at the Large Hadron Collider
This dissertation describes a search for resonant WW and WZ production in the lvjj decay channel using 4.701 fb-1 of sqrt(s) = 7 TeV LHC collision data collected by the ATLAS detector. Events with a single charged lepton, at least two jets and missing transverse energy are analyzed and no …

Precision measurement of and search for dark matter in the transverse momentum spectra of Z bosons
… on the irreducible background from electroweak diboson processes is constrained by emulating the missing energy using pure control samples in the fully leptonic final states. The data were collected with the Compact Muon Solenoid detector at the Large Hadron Collider and correspond to an …

Constraining New Physics with Colliders and Neutrinos
… to show up. In this case, we use the previous diboson and diphoton statistical excess as examples to do the analysis. Second, we parametrize low energy new physics in the neutrino sector in terms of non-standard interactions (NSI), which are constrained by past and proposed future neutrino …

New physics searches in the ZZ sector with the ATLAS experiment
… manifest themselves as an excess of events in ZZ diboson channels, and, if observed, would be a direct probe of new physics beyond the Standard Model. A set of criteria are outlined to select events recorded by ATLAS in two such channels, ZZ to llll(l = e, mu) and ZZ to llnunu. With 1 fb-1 of …

Effective Field Theories for Physics Beyond the Standard Model
… Theory (SMEFT) using data from the Higgs, top, diboson and electroweak sectors, combining these four data sectors in a global fit for the first time. We will assess the interplay between these sectors, shedding light on the interplay between the Higgs and top sectors in particular. By comparing …
