Quark Initial State Interaction in Deep Inelastic Scattering and the Drell - Yan process ∗
We pursue a phenomenological study of higher twist effects in high energy processes by taking into account the off-shellness (virtuality) of partons bound in the nucleon. The effect of parton off-shellness in deep inelastic ep → eX scattering (DIS) and the Drell-Yan process (pp → l ¯ lX) is examined. Assuming factorization and a single-parameter Breit-Wigner form for the parton spectral functio...

متن کاملInitial - State Interactions in the Unpolarized Drell - Yan Process ∗
We show that initial-state interactions contribute to the cos 2φ distribution in unpolarized Drell-Yan lepton pair production p p and p p → `+`−X, without suppression. The asymmetry is expressed as a product of chiral-odd distributions h1 (x1, p 2 ⊥) × h ⊥ 1 (x2, k 2 ⊥), where the quark-transversity function h1 (x, p 2 ⊥) is the transverse momentum dependent, light-cone momentum distribution of...
متن کاملInitial State Interactions , Factorization , and the Drell - Yan Process
We show that initial state interactions violate the factorization conjecture for the Drell-Yan process order by order in perturbation theory. We also discuss the effects of elastic and inelastic initial state interactions on the observed cross sections. A Talk Presented by G. T. Bodwin at the 1981 Banff Summer School on Particles and Fields Alberta, Canada, August 16-28, 1981 * Work supported b...
