Endpoint singularities in unintegrated parton distributions
We examine the singular behavior from the endpoint region x → 1 in parton distributions unintegrated in both longitudinal and transverse momenta. We identify and regularize the singularities by using the subtraction method, and compare this with the cut-off regularization method. The counterterms fo...
