Monte-Carlo Event Generator ExDiff

ExDiff processes (to be included to the generator)

Fig. 1 Amplitudes for exclusive diffractive processes: a) elastic scattering with Tel; b) general process of Central Exclusive Diffractive Production (CEDP) with central production born amplitude C and absorptive corrections Vin=V(s,b) and Vout=V(s',b). Versions of the CEDP Born amplitudes are: c) low mass resonance production; d) di-hadron production; e) high mass resonance production; f) high mass di-hadron production; g) di-jet production; h) nonperturbative photon-pomeron low mass resonance production; i) perturbative photon-pomeron high mass resonance production and j) high mass di-jet production. Possible additional corrections due to unitarization procedure are depicted as dotted ovals. In d) and f) it is possible to produce also di-bosons like gamma gamma, Z Z or W+ W- instead of di-hadrons h h.

Excluaive Diffractive PROcesses

Processes implemented into ExDiff v1.0.1 : elastic p p scattering at 7, 8, 13, 14 TeV and CEDP of f2(1950) at 13 TeV, f0(1710) and f0(1500) at 13 TeV and 8 TeV. Other processes will be added in next versions.

Other information on the investigations can be found on the web-page of the IHEP Diffractive Group
