Abstract

We analyze the possibility of studying the heavy flavour hadroproduction properties at the HERA-B experiment. In addition to the high statistics single inclusive B spectra measurements, the measurement of the BBbar meson correlations is considered. The techniques of momentum estimators, widely used in the charm sector, are demonstrated to be useful for the BBbar correlation studies at HERA-B. The kinematic limits for the precision of the momentum estimator within which the pair spectra can be measured are determined. The errors are weakly dependent on the topology of the multibody B meson decay.
