Measurement of the single top quark cross section in the lepton plus jets final state in proton-antiproton collisions at a center of mass energy of 1.96 TeV using the CDF II detector.
(, 2013-05-15)We present a measurement of the single top quark cross section in the lepton plus jets final state using an integrated luminosity corresponding to 7.5/fb of collision data collected by the Collider Detector at Fermilab. ... -
Nanocluster defects and their properties on TiO2(110) and (001) surfaces.
(, 2012-11-29)TiO2(110) and (001) have been investigated by low energy electron diffraction (LEED) and scanning tunneling microscopy (STM). A nearly bulk-like (1 × 1) TiO2(110) was produced after cycles of Ar+ sputtering and surface ... -
Nanomanipulator perturbation of dust crystals in a GEC rf plasma cell.
(2010-10-08)The vast majority of observable matter is composed of complex plasma. Even with its prevalence, the interactions between the plasma's constituents are not fully understood. In many cases, clouds of dust grains from and can ... -
Orbifold branes in string theory and their applications to cosmology.
(, 2011-09-14)This dissertation contains two distinct compactification schemes of 10-dimensional string theory, as well as some of the implications of one of these schemes for string cosmology. The first half of this work begins with a ... -
Probing interactions among molecules, substrate, and tip using tip-enhanced Raman spectroscopy.
(2017-07-31)Tip-Enhanced Raman Spectroscopy (TERS) has shown that spatial resolution <1 nm is possible, but is technically challenging and difficult even in Ultra-High Vacuum at low temperatures with plasmonic substrates. Here we ... -
Search for anomalous production of photon + jets + missing transverse energy in proton-antiproton collisions at a center of mass energy of 1.96 TeV using the CDF II detector.
(2011-05-12)A model-independent signature-based search for physics beyond the Standard Model is performed in the photon + jets + missing transverse energy channel in proton-antiproton collisions at a center of mass energy of 1.96 TeV ... -
Search for the Standard Model Higgs boson in the diphoton final state in proton-antiproton collisions at a center of mass energy of 1.96 TeV using the CDF II detector.
(, 2012-11-29)We present a search for the Standard Model Higgs boson decaying into a pair of photons produced in pp ̄ collisions with a center of mass energy of 1.96 TeV. The results are based on data corresponding to an integrated ... -
A search for the standard model Higgs boson produced in association with a W boson.
(2011-05-12)We present a search for a standard model Higgs boson produced in association with a W boson using data collected with the CDF II detector from proton/antiproton collisions at a center of mass energy of 1.96 TeV. The search ... -
Strange quark contribution to the nucleon.
(2007-02-07)The strangeness contribution to the electric and magnetic properties of the nucleon has been under investigation experimentally for many years. Lattice Quantum Chromodynamics (LQCD) gives theoretical predictions of these ... -
Studies on the missing energy measurement and supersymmetry search in 7 TeV proton-proton collisions.
(, 2012-11-29)The main theme of the research presented in this thesis is the search for Supersymmetry, one of the most likely and well-motivated extensions of the standard model of particle physics, in 7 TeV proton-proton collisions ... -
Surface embedded green function method applied to Ag(111).
(2010-10-08)Theoretical self-consistent calculations utilizing the Surface Embedded Green Function (SEGF) method have been performed on the Ag(111) surface. Analysis of the surface energetics reveal an energy minimum in the low ... -
Thomas Fermi model for mesons and new noise subtraction techniques in lattice QCD.
(2018-12-03)Lattice QCD calculations of quark loop operators are extremely time-consuming to evaluate. To calculate these diagrams we use stochastic noise methods, which employ a randomly generated set of noise vectors to project out ... -
