The Muon Detection System and W Z --> 3l̳(e̳, [mu]) cross section measurement at CMS
The startup of the Large Hadron Collider will allow scientists to probe energy scales that existed picoseconds after the Big Bang. Monte Carlo samples of many Standard Model processes are produced to simulate the conditions in the Compact Muon Solenoid detector. Data analysis techniques are …

Measurements of s(V+D*)/s(V) in 9.7 fb-1 at CDF Run II
The Standard Model of particle physics has been remarkably successful, but the non-perturbative features of quantum chromodynamics must be tested and modeled with data. There have been many such tests, focused primarily on the use of jet-based probes of heavy flavor (bottom and charm quark) …

Search For Trilepton Resonances From R-Parity Violating Chargino Decays In The B−l Mssm
This dissertation presents a search for the electroweak pair-production of charginos and the associated production of charginos and neutralinos in the B−L Minimal Supersymmetric Standard Model with spontaneous R-parity violation. The chargino and neutralino each decay via R-parity violating …

Theorems of Wiener-Lévy type for integral operators in C<sub>p</sub>
The classical theorem of N. Wiener and P. Lévy states that if f(x) has an absolutely convergent Fourier series and W(z) is an analytic function whose domain contains the range of f(x), then W[f(x)] also has an absolutely convergent Fourier series. The main result of this paper is an analog of the …

Effective field theories for the LHC
In this thesis I study applications of effective field theories to understand aspects of QCD jets and their substructure at the Large Hadron Collider. In particular, I introduce an observable, D2 , which can be used for distinguishing boosted W/Z/H bosons from the QCD background using information …

A measurement of W boson-photon and Z boson-photon cross sections in the muon channel in 1.8 TeV proton-antiproton collisions
We have measured the production cross sections x decay branching ratios for W + $\gamma$ and Z + $\gamma$ in the muon channel in $\sqrt{s}$ = 1.8 TeV p-p collisions, from 3.54 $\pm$ 0.24 $pb\sp{-1}$ of muon W and Z data from the CDF 1988-89 Tevatron collider run. For photons in the central region …

Study of the Higgs Boson Produced in Association with a Weak Boson and Decaying to WW* with a Same Sign Dilepton and Jets Final State in √ s =8 TeV pp Collisions with the ATLAS Detector at the LHC
The research described in this thesis is aimed at studying production of a Higgs boson in association with a W boson, in the H → W W ∗ decay mode, using 20 fb −1 of 8 TeV data collected in 2012. The specific final state studied in this thesis has the associated W boson and one of the W bosons from …

Inclusive Electroweak measurements in the muon channel with pp collisions at [the square root of] s=7 TeV
In this thesis, we perform the measurement of the production of W and Z bosons in proton-proton collisions at [the square root of]s = 7 TeV with the Large Hadron Collider (LHC). In the LHC, W and Z bosons are produced at a high rate, providing for large yields, which along with the clean signature …

The study of the production of heavy flavour muons as a function of charged-particle multiplicity in proton-proton collisions at 8TeV with ALICE at the LHC
ALICE (A Large Ion Collider Experiment) is a detector designed and optimized to study ultra relativistic heavy-ion collisions in which a hot, dense and strongly interacting Quantum Chromodynamics (QCD) medium called the Quark Gluon Plasma (QGP) is created. ALICE also studies proton-proton …

Simplified Template Cross Section measurements of associated V H production in the H → b¯b decay channel with √ s = 13 TeV proton-proton collisions at the ATLAS experiment
This thesis presents a Simplified Template Cross-Section (STXS) measurement of the production of the SM Higgs boson in association with a W or Z boson, where the Higgs boson decays to b ¯b and the W/Z boson (V ) decays leptonically. The data used is the full Run-2 ATLAS dataset, corresponding to …

Precision Measurements of the Vector Boson Scattering Production and Searches for Charged Higgs Bosons at the Large Hadron Collider
This thesis presents measurements of cross sections of vector boson pair production in association with two jets and a search for charged Higgs bosons (H superscript ±) decaying into a top and a bottom quark. The data samples used for the measurements are LHC proton-proton collisions recorded with …

MISSING TRANSVERSE ENERGY MEASUREMENT IN ATLAS DETECTOR:FIRST LHC DATA RESULTS AND IMPORTANCE FOR PHYSICS STUDY
The Large Hadron Collider (LHC) at CERN started its operation at the end of November 2009, first at a centre-of-mass energy of 900 GeV, then, since March 2010, at 7 TeV. During this period the ATLAS experiment has collected a large number of proton-proton collision events, resulting up to now in an …

Computational Bayesian techniques applied to cosmology
This thesis presents work around 3 themes: dark energy, gravitational waves and Bayesian inference. Both dark energy and gravitational wave physics are not yet well constrained. They present interesting challenges for Bayesian inference, which attempts to quantify our knowledge of the universe …
