Diffractive Dis Cross Sections and Parton Distributions
ثبت نشده
چکیده
Highlights are presented mainly from two recent measurements of the diffractive Deep Inelastic Scattering cross section at HERA. In the first, the process ep → eXp is studied by tagging the leading final state proton. In the second, events of this type are selected by requiring a large rapidity gap devoid of hadronic activity in the proton direction. The two measurements are compared in detail and the kinematic dependences are interpreted within the framework of a factorisable diffractive exchange. Diffractive parton distributions are determined from a next-toleading order QCD analysis of the large rapidity gap data, which can be applied to the prediction of diffractive processes, also at the TEVATRON and the LHC.

متن کاملDiffractive Interactions: Theory Summary
There has been an ongoing effort in the last years to describe diffractive DIS within the framework of QCD. Progress has been made in understanding the connections between different approaches, and we have had presentations about modelling the nonperturbative input needed in a QCD description. Soper [ 1] recalled that to leading twist accuracy, i.e. up to corrections in powers of 1/Q, the inclu...

متن کاملDiffraction at Hera and Implications for Tevatron and Lhc
We describe new QCD fits to diffractive cross sections measured at HERA and we use the parton densities derived from these fits to predict the shape of the dijet mass fraction in double Pomeron exchange at the Tevatron. We discuss the existence of exclusive events in this dijet channel and some prospects are given for the LHC. One of the most important experimental results from the DESY ep coll...
متن کاملDiffractive Parton Distributions in the Semiclassical Approach
Recently, a semiclassical approach to diffraction has been proposed, which treats the proton as a classical colour field. The present paper demonstrates that this approach is consistent with the concept of diffractive parton distributions. The diffractive quark and gluon distributions are expressed through integrals of nonAbelian eikonal factors in the fundamental and adjoint representation res...
