000058881 520__ $$9arXiv$$aThe cross section for ep -> e b\bar{b} X in photoproduction is measured with the H1 detector at the ep-collider HERA. The decay channel b\bar{b} -> ee X' is selected by identifying the semi-electronic decays of the b-quarks. The total production cross section is measured in the kinematic range given by the photon virtuality Q^2 <= 1 GeV^2, the inelasticity 0.05 <= y <= 0.65 and the pseudorapidity of the b-quarks |eta(b)|,|eta(\bar{b})| <= 2. The differential production cross section is measured as a function of the average transverse momentum of the beauty quarks <P_T(b)> down to the threshold. The results are compared to next-to-leading-order QCD predictions.

The transverse thrust axis, indicated by the dashed arrow, maximizes the sum of momenta projected onto it in this plane. The thrust axis allows the event to be divided into two hemispheres, each containing the decay products of a beauty quark, used to reconstruct the average transverse beauty mass $m_{T, \mathrm{rec}}(b)$ as defined in equation~\ref{eq: M_T_est}.
