结果表明,初态相互作用违反了通常的QCD因式分解预测,即在领先扭转中产生大量轻子对。初态碰撞修正了dsigma/dq/sup2/dx/subF/,也抹黑了轻子对的横向动量分布。
It is shown that initial-state interactions violate the usual QCD factorization predictions for massive lepton-pair production in leading twist. The initial-state collisions correct dsigma/dQ/sup 2/ dx/sub F/ and also smear the lepton-pair transverse momentum distribution.
