| Abstract |
The cross section of bb_bar photoproduction at threshold is measured using the
H1 detector at HERA. Events containing b-quarks are identified by
exploiting the semileptonic decay b->e X.
The analysis is based on data collected in the years 2006 and 2007 with a
dedicated low energy trigger, which combines track (Fast Track Trigger)
and calorimeter information (Jet Trigger).
With this new trigger events containing electrons at energies as low as 1.2
GeV were recorded. This allows for the study of b-quark production at low
transverse momentum, comparable to the b-quark mass.
Various distributions of differential cross sections of photoproduced b-quarks
are presented and compared to predictions. |
