Resummation of nuclear enhanced higher twist in the Drell-Yan process Academic Article uri icon


  • We investigate higher twist contributions to the transverse momentum broadening of Drell-Yan pairs in proton nucleus collisions. We reexamine the contribution of matrix elements of twist 4 and generalize this to matrix elements of arbitrary twist. An estimate of the maximal nuclear broadening effect is derived. A model for nuclear enhanced matrix elements of arbitrary twist allows us to give the result of a resummation of all twists in closed form. Subleading corrections to the maximal broadening are discussed qualitatively. 2003 The American Physical Society.
