โœฆ Synopsis

The HERA-B experiment has collected data on proton-induced collisions with three fixed nuclear targets at 41.6 GeV centre-of-mass energy. Preliminary results of an ongoing, detailed study of charmonium production include the determination of the nuclear dependence of the J/ฯˆ production kinematics (extending for the first time into the negative-x F region) and precise measurements of the feeddown components due to ฯ‡ c , ฯˆ and b-hadron decays. A new analysis of the J/ฯˆ decay angular distribution finds significant polarization effects in the low-momentum region, marginally touched by previous experiments. Measurements of the D-meson cross sections are consistent with the absence of nuclear suppression in open charm production.

We see copious production of charmed hadrons in the early LHCb data. The status and plans for charm production studies at LHCb are discussed, and preliminary signals are shown.

The status of beauty measurements at HERA is reviewed. A considerable improvement in the precision and kinematic coverage has been achieved in the last years. The results are in good agreement with NLO QCD.
