GENERAL CHARACTERISTICS OF Bc-MESONS: PRODUCTION MECHANISMS AND DECAYS

Abstract

Using Martin’s potential, independently of b- and c-quark flavours, we calculate the mass spectrum of [Formula: see text]-mesons and widths of electromagnetic transition between them. We obtain the estimates of the production cross-section at e+e− colliders, in hadronic and neutrino interactions. A real possibility of observing Bc-mesons at LEP (up to 500 Bc per 106 Z0) and at hadron colliders [Formula: see text] has been pointed out. The importance of observing the annihilation decay channels of Bc-mesons—Bc→τντ( Br (Bc→τντ)=1.5–2%) and Bc→ϕDs, DK, etc.—has been emphasized.
