Measurement of beauty photoproduction using dijet events with decays electrons 
with ZEUS at HERA
       	
Photoproduction of beauty was measured in events with two jets and an electron
associated with one of the jets with the ZEUS detector at HERA using an 
integrated luminosity of 120 pb-1. The fractions of events containing b 
or c quarks were extracted from a likelihood fit using variables sensitive 
to electron identification as well as to semileptonic decays. Total and 
differential cross sections for beauty and charm production are presented 
and compared to next-to-leading order QCD calculations and Monte Carlo models.
