We have written the Exclusive Hadronic Monte Carlo Event (ExHuME) generator. ExHuME is based around the perturbative QCD calculation of Khoze, Martin and Ryskin of the process pp→p+X+ppp→p+X+p, where X is a centrally produced colour singlet system.Program summaryTitle of program:ExHuMECatalogue identifier:ADYA_v1_0Program summary URL:http://cpc.cs.qub.ac.uk/summaries/ADYA_v1_0Program obtainable from:CPC Program Library, Queen's University of Belfast, N. IrelandLicensing provisions:NoneProgramming language used:C++, some FORTRANComputer:Any computer with UNIX capability. Users should refer to the README file distributed with the source code for further detailsOperating system:Linux, Mac OS XNo. of lines in distributed program, including test data, etc.:111 145No. of bytes in distributed program, including test data, etc.: 791 085Distribution format:tar.gzRAM:60 MBExternal routines/libraries:LHAPDF [http://durpdg.dur.ac.uk/lhapdf/], CLHEP v1.8 or v1.9 [L. Lönnblad, Comput. Phys. Comm. 84 (1994) 307; http://wwwinfo.cern.ch/asd/lhc++/clhep/]Subprograms used:Pythia [T. Sjostrand et al., Comput. Phys. Comm. 135 (2001) 238], HDECAY [A. Djouadi, J. Kalinowski, M. Spira, HDECAY: A program for Higgs boson decays in the standard model and its supersymmetric extension, Comput. Phys. Comm. 108 (1998) 56, hep-ph/9704448]. Both are distributed with the source codeNature of problem:Central exclusive production offers the opportunity to study particle production in a uniquely clean environment for a hadron collider. This program implements the KMR model [V.A. Khoze, A.D. Martin, M.G. Ryskin, Prospects for New Physics observations in diffractive processes at the LHC and Tevatron, Eur. Phys. J. C 23 (2002) 311, hep-ph/0111078], which is the only fully perturbative model of exclusive production.Solution method:Monte Carlo techniques are used to produce the central exclusive parton level system. Pythia routines are then used to develop a realistic hadronic system.Restrictions:The program is, at present, limited to Higgs, di-gluon and di-quark production. However, in principle it is not difficult to include more.Running time:Approximately 10 minutes for 10000 Higgs events on an Apple 1 GHz G4 PowerPC.
