Soft pions at high energy and its phenomenological implications
Abstract
Description
The soft pion theorem in the inclusive reaction at high energy applied to the current induced reaction is explained briefly. A characteristic aspect of this theorem is the charge asymmetry produced by the pole terms in the soft pion limit. The pion charge asymmetry in the central region in the target-virtual-photon center of the mass (CM) frame of the semi-inclusive electroproduction and the contribution to the Gottfried sum are illustrated as examples.
