Talk on QCD Calculations by Numerical Integration
Davison E. Soper
Calculations in Quantum Chromodynamics are typically performed using a method pioneered by Ellis, Ross and Terrano in 1981. In this method, one combines numerical integrations over…
Next-to-Leading Order Cross Sections for Tagged Reactions
Eric Laenen, Stephane Keller
We extend the phase space slicing method of Giele, Glover and Kosower for performing next-to-leading order jet cross section calculations in two important ways: we show how to incl…
Non-Perturbative Couplings and Color Superconductivity
Nick Evans, Stephen Hsu, Myckola Schwetz
Quark matter at sufficiently high density exhibits color superconductivity, due to attractive gluonic interactions. At lower densities of order , it has been proposed th…
GUT and SUSY Breaking by the Same Field
Kaustubh Agashe
We present a model in which the same modulus field breaks both SUSY and a simple GUT gauge group down to the SM gauge group. The modulus is stabilized by the inverted hierarchy mec…
An Effective Field Theory Approach to Color Superconductivity at High Quark Density
Nick Evans, Stephen D. H. Hsu, Myckola Schwetz
We investigate the Fermi Liquid theory of high density QCD. Using the renormalization group (RG), we determine the behavior of effective fermion interactions near the Fermi surface…
Electroweak Penguins, Final State Interaction Phases and CP Violatioin in Decays
Deshpande, Xiao-Gang He, Wei-Shu Hou +1
The recently observed , and decay modes appear to have nearly equal branching ratios. This suggests that tree and electroweak…
