چکیده
HERA-B is a hadroproduction experiment located at DESY in Hamburg, Germany. The experiment produces B mesons and baryons by inserting thin wire targets into the halo of the proton beam circulating in the HERA storage ring. The B decays are studied to search for evidence of CP violation and constrain the angle β and possibly γ and α of the CKM unitarity triangle. The experiment also produces B s mesons; these decays are studied to measure or constrain the mass difference ∆m s and width difference ∆Γ s between the two B 0 s /B 0 s mass eigenstates. Finally, the large number of B's produced allows HERA-B to search for rare and forbidden decays such as B → K (*) ℓ + 1 ℓ − 2. The experiment is scheduled to begin running in early 2000.

We study the diffractive production of high pt photons at HERA. We have implemented the process as a new hard sub-process in the HERWIG event generator in order to prepare the ground for a future measurement. PACS numbers: 12.38Cy, 13.60.Fz, 13.85.-t

Factorial, cumulant and H q-moments in dependence on their rank q for the instanton-induced deep inelastic scattering (DIS) in the frameworks of QCD are calculated and analysed. The obtained correlation moments behaviour has specific form, which can be considered as a new criterion of the QCD-instantons identification on experiment at HERA.
