Lepton mass effects in semileptonic B(c,s) meson decays using the WSB, ISGW, ISGW2, HEAVY QUARKS and LCSR models

In this work the lepton mass effects in semileptonic B(c,s) meson decays using the WSB, ISGW, ISGW2, HEAVY QUARKS (HQ) and LCSR models were studied. We computed branching ratios for B(c,s)→D(s,c)ℓνℓ decays and calculate the fractions R=B(B→Dτντ)B(B→Dℓνℓ) and R⁎=B(B→D⁎τντ)B(B→D⁎ℓνℓ)....
