12 Activation of Delta-isobar creation in the Reggeon cascading
12 Activation of Delta-isobar creation in the Reggeon cascading Model of nuclear disintegration in high-energy nucleus nucleus interactions. K. Abdel-Waged, V.V. Uzhinsky Phys.Atom.Nucl.60: ,1997, Yad.Fiz.60: ,1997. Delta-isobar creation in the Reggeon cascading was implemented, but was not activated. Now it is activated.

24 Conclusion Diffraction dissociation cross sections in PP-, Pi P- and K P interactions have been estimated. 2. Some bugs are fixed. Delta-isobars are activated. 3. A good description of exp. data on P A and Pi A interactions has been reached. Estimation of evaporated nucleon multiplicity and spectra is still problematic due to lack of exp. data. It would be well to use calorimetric data! The diffraction in hadron-nucleus interactions has to be studied more carefully. It would be well to improve the Bertini and QGS models. Diffraction in FTF can be checked in P+Pb interactions at LHC (4.4 TeV). The experiment will be carried out at November 2012. Gathered exp. data will be used for a revision of QGS model. 24
