Description: We analyze the tauonic semileptonic baryon decays Λ0b→Λ+c+τ−+ν̄ τ with particular emphasis on the lepton helicity flip contributions which vanish for zero lepton masses. We calculate the total rate, d ... More

Description: Recently there has been much interest in the tauonic semileptonic meson decays B→D+τ+ντ and B→D∗+τ+ντ, where one has found larger rates than what is predicted by the Standard Model. We analyze the cor ... More
