BHWIDE Unlike BABAMC used in the past BHWIDE includes the full exponentiation of radiation, i.e. arbitrary number of radiation photons can be generated. Also it takes into account the ISR-FSR interference. 

Only small samples of events in specific kinematic regions exist so far.

For LEP1: EK5533.27 events with acol < 20.0 and Prad < 1.0

For LEP2: XS_BHFO_E184_R97_1L_F3 and XS_BHFO_E189_R98_1L_A1 Events with 2 or more gammas above 0.8 GeV each.

 


Outstanding Problems:

The calculations are still only O(alpha) 
Model is not very reliable at very low angles
