Charm Production in Deep Inelastic Scattering from Threshold to High $Q^{2}
James Amundson, Carl Schmidt, Wu-Ki Tung +1
Charm final states in deep inelastic scattering constitute of the inclusive cross-section at small as measured at HERA. These data can reveal important information o…
Partonometry in W + jet production
James Amundson, Jon Pumplin, Carl Schmidt
QCD predicts soft radiation patterns that are particularly simple for production. We demonstrate how these patterns can be used to distinguish between the parton-level s…
Report of the Supersymmetry Theory Working Group
J. Amundson, G. Anderson, H. Baer +21
We provide a mini-guide to some of the possible manifestations of weak scale supersymmetry. For each of six scenarios we provide a brief description of the theoretical underpinning…
Quantitative Tests of Color Evaporation: Charmonium Production
J. F. Amundson, O. J. P. Eboli, E. M. Gregores +1
The color evaporation model simply states that charmonium production is described by the same dynamics as production, {\em i.e.}, by the formation of a colored $c \bar c…
Photoproduction of J/ in the forward region
James Amundson, Sean Fleming, Ivan Maksymyk
We study the phenomenology of fixed-target elastic photoproduction in the NRQCD factorization formalism. Our the goal is to test an essential feature of this formalism --- th…
Colorless States in Perturbative QCD: Charmonium and Rapidity Gaps
J. F. Amundson, O. J. P. E'boli, E. M. Gregores +1
We point out that an unorthodox way to describe the production of rapidity gaps in deep inelastic scattering, recently proposed by Buchmüller and Hebecker, suggests a description o…
