30. Decay rate of the $B_c$ meson in the Standard Model

Benjamin Grinstein (UCSD)

The Standard Model decay rate of the $B_c$ meson is discussed together with a novel approach based on the usage of experimental data in combination with an operator product expansion. In the new method differences of $B$, $D$ and $B_c$ meson widths are considered, for which the free-quark contributions drop out, possibly leading to a reduction of the uncertainty of the theoretical prediction.

40. CP violation in B mixing beyond next-to-leading order

Prof. Ulrich Nierste

17/06/2022, 10:00

I discuss the recently finished calculation of the next-to-next-to-leading order corrections to the CP asymmetry in flavour-specific $B_{d,s}$ decays and the phenomenological studies
which will be possible with better data.

24. Inclusive semi-leptonic B(s) mesons decay from Lattice QCD

Alessandro Barone (University of Southampton)

We address the non-perturbative calculation of the decay rate of the inclusive semi-leptonic B(s) mesons decay from lattice QCD. Precise theoretical Standard Model predictions are key ingredients in searches for new physics. This type of computation may eventually provide new insight into the long-standing tension between the inclusive and exclusive determination of the $V_{cb}$ and $V_{ub}$...

31. B meson decay constants from Lattice QCD

Matthew Black (University Siegen)

17/06/2022, 12:00

We present the status of ongoing work to extract pseudoscalar and vector decay constants for $B^{(*)}$, $B_s^{(*)}$ and $B_c^{(*)}$ mesons and determine phenomenologically interesting ratios such as $f_{B_s}/f_B$ or $f_{B^*}/f_B$. Our results extrapolated to physical quark masses and the continuum are compared to predictions by other lattice collaborations and QCD sum rules, and are used to...

32. Neutral B-meson mixing from the lattice

J Tobias Tsang (CP3-Origins, The University of Southern Denmark)

17/06/2022, 15:00

The combination of the experimentally measurable mass differences between the flavour eigenstates of neutral mesons and theoretical predictions of the corresponding hadronic matrix elements provide direct access to the CKM matrix elements $V_{td}$ and $V_{ts}$. Furthermore, the full dimension-6 operator basis provides valuable constraints for New Physics models. I will present the status of...
