Measurement of electroweak asymmetries in vector electron positron scattering at 0.1 less than Q(2) less than 0.4 (GeV/c)(2)

This work is based on the first engineering run of the G 0 experiment from October 2002 though January 2003 in Hall C at Jefferson Lab. The G0 experiment will be the first to measure the weak neutral form factors: GEZ( Q2), GMZ( Q2) and GAe( Q2) and to extract the proton\u27s strange form factors: GEs(Q2) and GMs(Q 2) via a Rosenbluth separation over a range of Q 2 (0.1--1.0 (GeV/c)2). This will require four sets of measurements: forward angle measurements with a proton target, and three sets of backward angle measurements with a hydrogen and deuterium target. The measurements are made of the parity-violating asymmetries in elastic electron scattering.;The G0 experiment is a major installation at Jefferson Lab\u27s Hall C with a new dedicated spectrometer. The superconducting magnet is made up of 8 coils with a maximum field of 1.6 T??m. The scintillator detector array (detector solid angle between 0.4--0.9 sr) detects recoiled protons in the forward angle measurement (where thetap = 70?? +/- 10?? corresponding to scattered electron angles of a few degrees) and to detect scattered electrons in the backward angle measurements. This detector array is made up of a set of 16 pairs of scintillators arranged in 8 sectors around the beam line. Custom electronics handle the high data rate (approximately 1 MHz per detector). The target is a 20 cm long liquid hydrogen cryotarget. Besides the check-out of the new hardware, G 0 has stringent requirements on the performance of the polarized electron beam in order to minimize false asymmetries. Further complicating this fact, in the forward mode, was the requirement that the time structure of the JLab beam had to be changed from 499 MHz to 31 MHz in order to count the recoiled protons in the spectrometer. Data was collected over a 12 day period at the end of the engineering run. These data were analyzed for a Q2 range of 0.1--0.4 (GeV/c) 2 corresponding to measured electroweak asymmetries that ranged from (-4.4 +/- 1.6 +/- 1.6 ppm) to (-8.5 +/- 2.8 +/- 2.5 ppm)

Arbitrary Rotated Coordinate Systems for the Inclined Plane as an Introduction to Group Theory in the Introductory Physics Classroom

The elementary problem of a block sliding down an inclined plane is examined in detail with respect to different oriented coordinate systems that are typically not utilized due to the complexity of the problem. After solving for the equation of motion in these different coordinate systems group theory is applied and shown to yield the same results

Construction and Characterization of Representations of SU(7) for GUT Model Builders

The natural extension to the SU(5) Georgi-Glashow grand unification model is to enlarge the gauge symmetry group. In this work, the SU(7) symmetry group is examined. The Cartan subalgebra is determined along with their commutation relations. The associated roots and weights of the SU(7) algebra are derived and discussed. The raising and lowering operators are explicitly constructed and presented. Higher dimensional representations are developed by graphical as well as tensorial methods. Applications of the SU(7) Lie group to supersymmetric grand unification as well as applications are discussed
