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.
ExDiff is a Monte Carlo event generator for simulation of Exclusive Diffractive processes in proton-proton collisions. The present version ExDiff v2.0 includes reactions:
In the future versions many other processes of CEDP will be added.
Other information on the investigations can be found on the web-page of the IHEP Diffractive Group
GeneratorSource files for the latest version ExDiff v2.0. Since tables for models are rather big, you can also download the generator without them .
At this moment you can use documents
You can download also more old version of the generator. Processes implemented into ExDiff v1.0.2 : 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.
