The contribution of $B_c$ mesons to the search for $B^{+} \to \tau^{+}\nu_{\tau}$ decays at LEP

We study the contribution of B_c mesons to the search for B->tau nu decays. We find that at LEP the contributions from B_u and B_c mesons can be comparable. This observation can have a relevant impact on the extraction of constraints on new physics (such as charged-Higgs contributions) from curre...
