Neutron-deuteron elastic scattering and three-nucleon force
(Massachusetts Institute of Technology, 2005)
The differential cross section for neutron-deuteron elastic scattering was measured at six angles over the center-of-mass angular range 65⁰ - 1300⁰ and incident neutron energies 140 - 240 MeV at the LANSCE/WNR facility of ...
Charged hadron transverse momentum spectra in Au+Au and d+Au collisions at 200 GeV per nucleon pair
(Massachusetts Institute of Technology, 2005)
The Relativistic Heavy Ion Collider (RHIC) collides Au ions at a center of mass energy of 200 GeV per nucleon pair, which produces the most energetic collisions yet seen in the laboratory. RHIC has also collided proton ...
Binary star systems and extrasolar planets
(Massachusetts Institute of Technology, 2005)
For ten years, planets around stars similar to the Sun have been discovered, confirmed, and their properties studied. Planets have been found in a variety of environments previously thought impossible. The results have ...
Constraints on early-type galaxy structure from spectroscopically selected gravitational lenses
(Massachusetts Institute of Technology, 2005)
This thesis describes all aspects of a unique spectroscopic survey for strong galaxy-galaxy gravitational lenses: motivation, candidate selection, ground-based spectroscopic follow-up, Hubble Space Telescope imaging, data ...
Gapless color superconductivity
(Massachusetts Institute of Technology, 2005)
In this thesis, we propose and investigate the "Gapless Color-Flavor Locked" (gCFL) phase, a possible new phase of dense and cold quark matter. At high enough densities, quarks interact with each other and form pairs ...
Evolution and statistics of biological regulatory networks
(Massachusetts Institute of Technology, 2005)
In this thesis, I study the process of evolution of the gene regulatory network in Escherichia coli. First, I characterize the portion of the network that has been documented, and then I simulate growth of the network. In ...
Spectral changes during the 0.1-4 Hz quasi-periodic oscillations in the black hole X-ray binary XTE J1550-564
(Massachusetts Institute of Technology, 2005)
In this thesis, we describe the analysis of 0.1-4 Hz quasi-periodic oscillations (QPOs) of the black hole X-ray binary XTE J1550-564 using data obtained with the Rossi X-ray Timing Explorer (RXTE) satellite. Data from 13 ...
Radiation transport around Kerr black holes
(Massachusetts Institute of Technology, 2005)
This Thesis describes the basic framework of a relativistic ray-tracing code for analyzing accretion processes around Kerr black holes. We begin in Chapter 1 with a brief historical summary of the major advances in black ...
Study of flavor tagging with semi-exclusive reconstruction of b [right arrow] D(sigma)X decays
(Massachusetts Institute of Technology, 2005)
The BaBar experiment measures CP violation in the B meson system by analyzing the decays of B⁰B̄⁰ pairs in which one of the mesons decays into a CP eigenstate. By measuring the decay time distribution separately for B⁰ and ...
An accurate analytical framework for computing fault-tolerance thresholds using the [[7,1,3]] quantum code
(Massachusetts Institute of Technology, 2005)
In studies of the threshold for fault-tolerant quantum error-correction, it is generally assumed that the noise channel at all levels of error-correction is the depolarizing channel. The effects of this assumption on the ...
