bhabha scattering

Asked by Shanmuka

For Bhabha scattering, e+ e- > e+ e-, I get a zero total cross-section at 13TeV. Is there something in the cards that should be changed?

 Thanks

Dear Shanmuka,

Have you set the beam identities lpp1 and lpp2 to 0 so as to turn off PDF's? If yes, please include your run_card.dat file.
