Abstract: The high-energy tails of charged- and neutral-current Drell-Yan processes provide important constraints on the light quark and anti-quark parton distribution functions (PDFs) in the large-x region. At the same time...
A positive-weight next-to-leading-order Monte Carlo for e<sup>+</sup>e <sup>-</sup> annihilation to hadrons
We apply the positive-weight Monte Carlo method of Nason for simulating QCD
processes accurate to Next-To-Leading Order to the case of e+e- annihilation to
hadrons. The method entails the generation of the hardest gluon emission...
Limits and Constraints on Mechanisms of Cell-Cycle Regulation Imposed by Cell Size-Homeostasis Measurements.
Herwig++1.0
Results from the new Monte Carlo event generator Herwig++ are presented. This
first version simulates Hadron Emission Reactions With Interfering Gluons in
electron-positron annihilation. The parton shower evolution is carried...
Coalescence model for theta(c) pentaquark formation
We present a model for the formation of the charmed pentaquark Theta_c in
hard scattering processes such as deep inelastic scattering, e^+e^-
annihilation, and high-energy p pbar collisions. The model assumes that the
cross...
