We review applicability of QCD factorization theorem to multiple scattering in deeply inelastic lepton-nucleus scattering. We show why A1/3-type nuclear enhancement can be calculated consistently in perturbative QCD. We derive the transverse momentum broadening of the leading pions in deeply inelastic lepton-nucleus collisions. We argue that the measurement of such transverse momentum broadenin...

We present a new preliminary measurement of the inclusive jet cross section in p¯ p collisions based on a integrated luminosity of about 0.8 fb −1. The data were acquired using the DØ detector between 2002 and 2005. Jets are reconstructed using an iterative cone algorithm with radius Rcone = 0.7. The inclusive jet cross section is presented as a function of transverse jet momentum and rapidity....
