Journal of High Energy Physics, 2023 We update the Standard Model (SM) predictions for B-meson lifetimes within the heavy quark expansion (HQE). Including for the first time the contribution of the Darwin operator, SU(3) F breaking corrections to the matrix element of dimension-six four ...Alexander Lenz, Maria Laura Piscopo, Aleksey V.

, 1996 We apply HQET to semi-leptonic $B$ meson decays into a variety of excited
charm states. Using three realistic meson models with fermionic light degrees
of freedom, we examine the extent that the sum of exclusive single charmed
states account for the ...A. Ali, A. F. Falk, B. Barish, C. Goebel, C. Long, D. Buskulic, D. LaCourse, D. Scora, E. E. Salpeter, E. E. Salpeter, G. Altarelli, G. Hardekopf, G. Hardekopf, H.

Nuclear Physics B - Proceedings Supplements, 2001 We present results for the semi-leptonic and leptonic decays of B mesons. These non-perturbative matrix elements are important for constraining the CKM matrix. Results are presented for the pseudoscalar and vector decay constants, as well as flavour breaking ratios and heavy quark symmetry relations.UKQCD Collaboration, Maynard, C.
