A study of possible new heavy-flavour production at the CERN (pp) Collider

Summary

In this paper, we review briefly the main hypotheses and extrapolations used to predict the observability of new heavy flavours at the CERN (pp) collider. Some results from this study are compared with the first experimental data on the production of high-p _T electrons accompained by hadronic « jets » at the (pp) collider, as observed by the UA1 collaboration. These events could, in fact, be the signature of the semi-leptonic decay of a very massive new heavy-flavoured state. Its « downlike » or « uplike » nature cannot be established in a direct and unambiguous way. More sophisticated measurements are needed as discussed in detail in a previous paper.
