Top-Quark Mass and Bottom-Quark Decay [PDF]

open access: yes, 1983
The possibility of a long B-meson lifetime is explored, in which case the weak mixing angles θ_2 and θ_3 are quite small. This allows the derivation of a lower bound on the top-quark mass as a function of the B-meson lifetime, by comparison of the short ...

A Theoretical Prediction of the Bs-Meson Lifetime Difference [PDF]

open access: yes, 2000
We present the results of a quenched lattice calculation of the operator matrix elements relevant for predicting the Bs width difference. Our main result is (\Delta\Gamma_Bs/\Gamma_Bs)= (4.7 +/- 1.5 +/- 1.6) 10^(-2), obtained from the ratio of matrix ...
