Heavy flavours in collider experiments

Current issues in the studies of heavy flavours in colliders are described with particular emphasis on experiments in which the UK is involved. Results on charm production at HERA are examined and compared with those at the Tevatron. B production rates at the Tevatron as well as the status of B lifetimes and mixing in the LEP collaborations and at the Tevatron are highlighted. The measurement of sin 2β from CDF is described as well as the most recent results on top physics at the Tevatron. (author)
