Diffractive Dissociation into Two Jets
We report a study of the processes of coherent a pion and a photon diffraction dissociation into two jets. The structure of non-factorizable contributions in these reactions is discussed. We argue that production of hard dijets by real photons can provide direct evidence for chirality violation in hard processes and the first measurement of the magnetic susceptibility of the quark condensate.
متن کاملDiffractive Dissociation of High Momentum Pions
The diffractive dissociation of 500 GeV/c π− into di-jets is described as a way to measure the momentum distribution of quarks in the pion. The measurements of the pion diffractive dissociation were carried out using data from Fermilab E791. Preliminary results show that the |qq̄〉 Asymptotic wave function which was developed using perturbative QCD methods describes the data well for Q2 ∼ 10 (GeV...
متن کاملQuark-Antiquark Production in DIS Diffractive Dissociation
We calculate the cross section for the production of two jets with large transverse momenta k in DIS diffractive dissociation for both transverse and longitudinally polarized photons. The scale which defines the hardness of the Pomeron is found to be k Q 2 +M M . We present analytic expressions and discuss numerical results relevant for the diffractive dissociation at HERA. 1.) The diffractive ...
متن کاملDIFFRACTIVE NUCLEON DISSOCIATION BY n ' AT
Data is presented on the reactions sip-t IT'PIT' and "'p-t .ir'nn+ from the SLAC hybrid bubble chamber triggered on a fast forward pion. Diffractively produced resonance structure is observed, closely resembling that seen in pp + pnlr+ at ISR energies.
متن کاملQuark-Antiquark Jets in DIS Diffractive Dissociation
We report on investigations concerning the production of large transverse momentum jets in DIS diffractive dissociation. These processes constitute a new class of events that allow for a clean test of perturbative QCD and of the hard (perturbative) pomeron picture. The measurement of the corresponding cross sections might possibly serve to determine the gluon density of the proton.
