A Measurement of the Jet Multiplicity in Di-lepton Final States of ttbar Events
A measurement of the jet multiplicity in di-leptonically decaying ttbar events (i.e. ttbar → (ee, μμ, eμ) + missing transverse momentum + jets) is presented, using 4.66 fb -1 of data collected from √ s = 7 TeV pp collisions at the CERN Large Hadron Collider. In order to mitigate the effects of …

Measurement of top-antitop differential cross sections in the di-lepton channel with ATLAS in p-p collisions at 7TeV
This dissertation presents a measurement of differential cross sections as a function of mass, transverse momentum and rapidity of the top quark pairs using $\sqrt{s} = 7 \TeV$ proton-proton collision data collected by the ATLAS detector at the Large Hadron Collider. This data corresponds to an …

Direct search for exotic spin zero particles in the di-lepton final state of Higgs-Z associated production in sqrt(s) = 13 TeV pp collisions
… uses Higgs-Z---associated production with two leptons in the final state. The analysis uses a likelihood-fit profile of a multivariate discriminant to place 95% confidence limit upper bounds on the cross section of the proposed signal. A study of the performance of the ATLAS Tile Calorimeter in …

Using Heavy Flavors To Study New Physics
<p>In this doctoral dissertation I discuss the possible standard model contributions to select leptonic heavy meson decay modes. Included are calculations of soft photon contributions to a di-lepton decay of B-mesons as well as two-particle hadronic unitary contributions to the rare di-leptonic …

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
… collected in 2012. The specific final state studied in this thesis has the associated W boson and one of the W bosons from the Higgs decaying leptonically, while the last W boson decays hadronically, giving two leptons, jets, and missing transverse energy as the final state signature in the …
