Charm quark mass using a massive nonperturbative renormalisation scheme
/ Del Debbio, Luigi (Piemonte Orientale U., Alessandria ; INFN, Turin) ; Erben, Felix (CERN) ; Flynn, Jonathan (Southampton U.) ; Mukherjee, Rajnandini (Southampton U.) ; Tsang, J. Tobias (CERN)
We present a first numerical implementation of a massive nonperturbative renormalisation scheme, RI/mSMOM, in the study of heavy quarks using the domain-wall fermion action. In particular, we calculate renormalisation constants for fermion bilinears at non-vanishing heavy-quark masses and compare the approach to the continuum of the renormalised charm-quark mass with that from a mass-independent scheme..

The $I$ = 1/2 and 3/2 $K-\pi$ scattering length with domain wall fermions at physical pion mass with all-to-all propagators

We present our calculations for the $I$ = 1/2 and 3/2 $K-\pi$ s-wave scattering length with physical quark masses, extracted from the interaction energy of Euclidean two-point functions. We use the domain wall fermion action with physical quark masses at a single lattice spacing. [...]

Isospin-breaking corrections to light leptonic decays in lattice QCD+QED at the physical point
/ Hermansson-Truedsson, Nils (U. Bern, AEC ; Lund U., Dept. Theor. Phys.) ; Boyle, Peter (Edinburgh U. ; Brookhaven) ; Di Carlo, Matteo (Edinburgh U.) ; Erben, Felix (Edinburgh U.) ; Gülpers, Vera (Edinburgh U.) ; Hansen, Maxwell T. (Edinburgh U.) ; Harris, Tim (Edinburgh U.) ; Hodgson, Raoul (Edinburgh U.) ; Jüttner, Andreas (CERN ; Southampton U.) ; hÓgáin, Fionn Ó. (Edinburgh U.) et al.
We report on the physical-point RBC/UKQCD calculation of the leading isospin-breaking corrections to light-meson leptonic decays. This is highly relevant for future precision tests in the flavour physics sector, in particular the first-row unitarity of the Cabibbo-Kobayashi-Maskawa matrix containing the elements $V_{us}$ and $V_{ud}$.

Isospin-breaking corrections to light-meson leptonic decays from lattice simulations at physical quark masses
/ Boyle, Peter (Brookhaven ; Edinburgh U.) ; Di Carlo, Matteo (Edinburgh U.) ; Erben, Felix (Edinburgh U.) ; Gülpers, Vera (Edinburgh U.) ; Hansen, Maxwell T. (Edinburgh U.) ; Harris, Tim (Edinburgh U.) ; Hermansson-Truedsson, Nils (Bern U. ; Lund U., Dept. Theor. Phys.) ; Hodgson, Raoul (Edinburgh U.) ; Jüttner, Andreas (Southampton U. ; CERN) ; hÓgáin, Fionn Ó. (Edinburgh U.) et al.
The decreasing uncertainties in theoretical predictions and experimental measurements of several hadronic observables related to weak processes, which in many cases are now smaller than $\mathrm{O}(1\%)$, require theoretical calculations to include subleading corrections that were neglected so far. Precise determinations of leptonic and semi-leptonic decay rates, including QED and strong isospin-breaking effects, can play a central role in solving the current tensions in the first-row unitarity of the CKM matrix.
