Need for fully unintegrated parton densities
John Collins, Hannes Jung
Associated with the use of conventional integrated parton densities are kinematic approximations on parton momenta which result in unphysical differential distributions for final-s…
What exactly is a parton density?
John C. Collins
I give an account of the definitions of parton densities, both the conventional ones, integrated over parton transverse momentum, and unintegrated transverse-momentum-dependent den…
Rapidity and Transverse Momentum Distributions of DIS 1-jet Inclusive Cross Section -- A Next-to-Leading Order Monte-Carlo Prediction
John Collins, Xiaomin Zu
We have implemented in the RAPGAP program a previously derived subtraction method for next-to-leading order (NLO) corrections in Monte-Carlo event generators, and we show results f…
Spontaneously Broken Chiral Symmetry and Hard QCD Phenomena
M. J. Amarian, V. M. Braun, S. J. Brodsky +28
These are the mini-proceedings of the workshop ``Spontaneously Broken Chiral Symmetry and Hard QCD Phenomena" held at the Physikzentrum Bad Honnef from July 15 to 19, 2002. Every a…
QCD and Diffraction
John Collins
I review some of the main results on hard diffraction, in their relation to QCD, and indicate some of the strengths and weaknesses of the arguments. I also make some suggestions fo…
Tests of goodness of fit to multiple data sets
J. C. Collins, J. Pumplin
We propose a new and rather stringent criterion for testing the goodness of fit between a theory and experiment. It is motivated by the paradox that the criterion on χ^2 for testin…
