Abstract We present the EKHARA Monte Carlo event generator of reactions e ^+ e^- →e^+ e^- π^0and e^+ e^- →e^+ e^- π^+ π ^- . The newly added channel (e^+ e^- →e ^+ e^- π^0 ) is important for γ ^* γ^*physics and can be used for the pion transition form factor studies at meson factories. Title of program: EKHARA Catalogue Id: AEIO_v1_0 Nature of problem The first version of EKHARA [1,2] was developed to simulate a background for the pion form factor measurement at meson factories coming from the process e + e - → e + e - π + π - . The newly added channel, e + e - → e + e - π 0 , will help in the pion transition from factor studies at meson factories [3]. Versions of this program held in the CPC repository in Mendeley Data AEIO_v1_0; EKHARA; 10.1016/j.cpc.2011.01.029 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)
