[en] We discuss the high energy diffractive dissociation in DIS at the Next to Leading Order. In the large N_c dipole limit we derive the NLO version of the Kovchegov–Levin equation. We argue that the original structure of the equation is preserved, that is it coincides with the Balitsky–Kovchegov equation at NLO

[en] The model of soft diffractive dissociation proposed some time ago by Miettinen and Pumplin is shown to describe correctly the data at FERMILAB energies. The comparison with Goulianos model of renormalized pomeron flux is also presented

[en] This book is a basic introduction to kinematic methods used in studying elementary-particle interactions. Specific topics include kinematics of two-particle scattering, kinematics of multiperipherality, and kinematic variables of lepton-nucleon interaction. It includes original references and a separate bibliography of citations

[en] The expectations based on multiperipheral picture are compared with the main features of the most ineresting ISR results concerning one particle distributions with the s ranging from 60 GeV² to 3000 GeV². The comparison shows that qualitative features of the ISR data fit very nicely in the multiperipheral framework. As the ladder approximation has several unpleasant properties several attempts to enlarge the notion of multiperipheralism beyond the ladder approximation have been made and the results are described. The definition of any multiperipheral model given by Basseto, Sertorio and Toller is recalled and recent results obtained with these models are reviewed. (S.B.)

[en] Some simple general features of the diffractive hadron dissociation process are discussed with emphasis on its relation to elastic scattering and the total cross section of hadrons. (author)
