PHOTOS interface in C++ Technical and physics documentation
Description
Abstract For five years now, PHOTOS Monte Carlo for bremsstrahlung in the decay of particles and resonances has been available with an interface to the C++ HepMC event record. The main purpose of the present paper is to document the technical aspects of the PHOTOS Monte Carlo installation and present version use. A multitude of test results and examples are distributed together with the program code. The PHOTOS C++ physics precision is better than its FORTRAN predecessor and more convenient steering ... Title of program: Photos++ Catalogue Id: AEYF_v1_0 Nature of problem Algorithm described in this paper can be used to add final state radiation to the event generated by external software using selected event record format. It can also be used on a sample of events loaded from data file. User can define parts of the decay tree on which algorithm can be invoked. The influence of the next-to-leading-order corrections, along with other options regarding electron-positron pair, muon pair and photon emission, can be studied. Versions of this program held in the CPC repository in Mendeley Data AEYF_v1_0; Photos++; 10.1016/j.cpc.2015.09.013 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)
