Particle Physics In The Lhc Era, Don Bunk May 2013

Particle Physics In The Lhc Era, Don Bunk

Physics - Dissertations

During the past 100 years experimental particle physicists have collected an impressive amount of data. Theorists have also come to understand this data extremely well. It was in the first half of the 20th century the efforts of the early pioneers of quantum mechanics laid the ground work for this understanding: quantum field theory. Through the tireless efforts of researchers during the later half of the 20th century many ideas came together to form what we now call the Standard Model (SM) of particle physics. Finally, it was through the ideas of the renormalization group and effective field theory that ...


Linear Sigma Models In Qcd And S3 Symmetry For Neutrinos, Muhammad Naeem Shahid Aug 2012

Linear Sigma Models In Qcd And S3 Symmetry For Neutrinos, Muhammad Naeem Shahid

Physics - Dissertations

This thesis has two parts with different topics in particle physics. In part I, we consider various linear sigma models and their applications to scalar mesons. It is shown that the tree amplitude for ππ scattering in the minimal linear sigma model has an exact expression which induces an infinite geometric series in which the pattern for both the I = 0 and I = 2 s-wave scattering lengths to orders $p^2$, $p^4$ and $p^6$ seems to agree with chiral perturbation theory predictions. The model is then gauged to study the mass differences between the vector meson and the ...


Supersymmetric Yang-Mills Theories On The Lattice, Anosh Joseph Jan 2011

Supersymmetric Yang-Mills Theories On The Lattice, Anosh Joseph

Physics - Dissertations

This dissertation reviews the formulation of twisted supersymmetric Yang--Mills (SYM) theories in the continuum and also on the lattice. We focus on the maximally supersymmetric twisted SYM theories in four and two dimensions. The one-loop renormalization of the lattice four-dimensional SYM theory is investigated. We also study the thermal phase structure of the maximally supersymmetric SYM in two dimensions and possible black hole transitions in its dual gravitational theory, using numerical simulations of the lattice theory.
