By considering this expansion around different spacetime points,ve also compute the non-local terms together with the more usual divergent ones. Finally, we discuss the applicability of our results to the calculation of particle production probabilities.engjournal articlehttp://iopscience.iop.org/0264-9381/16/12/321http://iopscience.iop.orghttp://arxiv.org/abs/hep-th/9712198open access53Symmetry-Breaking SectorGenerated Parton DistributionsStrongly Interacting WsHigh-Energy CollisionsStandard ModelFísica (Física)22 Física
