Search for the rare decay of the muon into a positron and a photon
This dissertation examines some of the more subjective aspects of individuals' experiences of isolation within the context of racialized and gendered work organizations. This research develops two constructs--institutional and social isolation--and attempts to ascertain the extent to which racial …

Construction of an ultra-thin cylindrical drift chamber for measurement of the rare decay K+ [formula]
The branching ratio for the decay K+ [formula] has been measured at Brookhaven National Laboratory by the E787 collaboration to be 5.2 x 10-9. The best QCD calculations give a prediction of (.6 -4 6) x 10'. The theoretical equations for this calculation as well as the previous experiment are …

SEARCH FOR THE RARE DECAY OF A B MESON TO A K MESON AND TWO NEUTRINOS
We search for the exclusive decays B -> (K+,KS,K*+,K*0)nu nubar in a sample of 9.7 million charged and neutral B meson decays recorded by the CLEO detector at the Y(4S)resonance. The technique was one of full event reconstruction where after electing a signal B candidate the remainder of the event …

Quality assurance of the VELO modules and analysis of the Bd->K*\mu^+\mu^- rare decay on LHCb
… construction and preparatory studies for a rare decay analysis. Quality assurance of the silicon modules of LHCb vertex detector One of the critical components of the LHCb experiment is the silicon vertex locator (VELO), which is used to measure the decay distance of the $b$-hadrons and is a …

B → K∗µ+µ− and Form Factors for Semi-Leptonic and Radiative B Decays
… and of these semi-leptonic and radiative B decays will play a leading role in the search for new physics (NP). A prime example is the rare decay B→K∗(→ Kπ)µ+µ−, where the many measurable quantities offer important new tests of the Standard Model and its extensions. We define sets of …

Mobility and fluorescence of barium ions in xenon gas for the EXO experiment
… aims to observe the neutrinoless double beta decay of 136Xe. The measurement of this decay would give information about the absolute neutrino mass and whether or not the neutrino is its own antiparticle. Since this is a very rare decay, the ability to reject background events by detecting the …

PROBING THE HIGGS BOSON WITH THE ATLAS DETECTOR: PRECISION MEASUREMENTS OF THE MASS AND SEARCH FOR RARE DECAYS TO A LOW-MASS DILEPTON SYSTEM AND A PHOTON IN PROTON-PROTON COLLISIONS AT THE LHC
… the Higgs boson mass $m_H$, and the search for a rare SM decay mode not yet observed, namely the decay into a low-mass dilepton system and a photon. \noindent The first analysis presents a precision measurement of the Higgs boson mass in the diphoton decay channel, $H \rightarrow \gamma\gamma$, …

Using Heavy Flavors To Study New Physics
… 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 decay of the neutral D meson. Additionally, constraints are …
