Identification of multiparticle final states in completely exclusive reactions based on the topology and kinematics of events

Abstract

Methodological part of analysis of the coherent photoproduction of a proton-antiproton pair based on experimental data obtained at CLAS facility of the Jefferson Linear Accelerator Laboratory (USA) is represented. The beam of tagged photons with energies up to 5.75 GeV used in the experiment was incident on 40 cm long liquid deuterium target. The description of methods for identification of multiparticle final states in completely exclusive reactions is given. It is shown how the kinematics of coherent photoproduction of \(\gamma \bar p\), π+π−, k+k− pairs was used for identification of final state particles and reactions.
