Observable signatures of general relativistic dynamics in compact binaries
(Massachusetts Institute of Technology, 2009)The effects of general relativity (GR) in astrophysical systems are often difficult to calculate, but they can have important consequences for observables. This thesis considers the impact of previously-ignored GR effects ... -
Observation and examination of a Higgs boson in the ZZ to four lepton channel
(Massachusetts Institute of Technology, 2014)Results are presented on 5.1 fb- 1 of proton-proton collisions at a center of mass energy of 7 TeV and 19.7 fb- 1 at 8 TeV in a search for decays of the Standard Model (SM) Higgs boson to two Z bosons to four charged ... -
Observation and measurement of a standard model Higgs Boson-like diphoton resonance with the CMS detector
(Massachusetts Institute of Technology, 2015)This thesis concerns the observation of a new particle and the measurements of its properties, from the search of the Higgs boson through its decay into two photons at the CMS experiment at CERN's Large Hadron Collider ... -
Observation and modeling of atmospheric oxygen millimeter-wave transmittance
(Massachusetts Institute of Technology, 1998) -
Observation of [pi]-B meson charge-flavor correlations and measurement of time dependent B⁰⁰ mixing in pp collisions

Observation of B⁰s - B⁻⁰s oscillations and the development and application of same-side-kaon flavor tagging
(Massachusetts Institute of Technology, 2007)The search for flavor oscillations in the neutral Bs - B meson system constitutes a flagship analysis of the Tevatron proton-anti-proton collider physics program and an important probe for effects due to new physics beyond ... -
Observation of B⁰s - B⁻⁰s oscillations using partially reconstructed hadronic Bs decays
(Massachusetts Institute of Technology, 2008)This thesis describes the contribution of partially reconstructed hadronic decays in the world's first observation of B⁰s - B⁻⁰s oscillations. The analysis is a core member of a suite of closely related studies whose ... -
Observation of electroweak W±W± JJ production with the CMS experiment
(Massachusetts Institute of Technology, 2017)The CMS detector at the CERN LHC is sensitive to Standard Model predictions regarding the production of two W bosons with the same charge accompanied by two jets. In particular, when these particles are produced in a ... -

Obtaining 1D dynamics in a quasi-1D NMR spin system
(Massachusetts Institute of Technology, 2008)In this thesis, I explored the evolution and dynamics of multiple quantum coherences in a quasi-iD crystal lattice, Fluorapatite (FAp), through the use of NMR. In particular I focused on the system with chains aligned with ... -
Octave-spanning lasers for optical metrology applications
(Massachusetts Institute of Technology, 2006)This thesis describes the first octave-spanning frequency comb based on a prismless, Ti:sapphire laser. It covers in detail the design and construction of the laser system, as well as the electronic stabilization scheme ...
