   <hidden TTP03-30  e+e- -> pi+pi-e+e-: a potential background for sigma(e+e- ->pi+pi-) measurement via radiative return method >   A Monte Carlo generator (EKHARA) has been constructed to simulate the
 reaction e+e- -> pi+pi-e+e- based on initial and final state emission of a e+e-
 pair from e+e- -> pi+pi- production diagram. A detailed study of the process,
 as a potential background for sigma(e+e- -> pi+pi-) measurement via radiative
 return method, is presented for phi- and B- factory energies.
