Description
A way to determine luminosity at ILC is to measure Bhabha scattering in the
LumiCal. For physics requirements, one needs to reach a precision of 10^-4 for the
luminosity determination and thus the Bhabha cross section. Whereas studies on
theoretical uncertainties on the cross section and on mis-identified Bhabhas in the
LumiCal are fully performed, bias on Bhabha measurement due to beam-beam effect has
never been investigated before. Using GUINEA-PIG, we start to study how
electromagnetic deflections due to beam-beam effect play a non negligible role on
the Bhabha angular distribution.
