Kaon physics is at a turning point -- while the rare-kaon experiments NA62 and KOTO are in full swing, the end of their lifetime is approaching and the future experimental landscape needs to be defined. With HIKE, KOTO-II and LHCb-Phase-II on the table and under scrutiny, it is a very good moment in time to take stock and contemplate about the opportunities these experiments and theoretical developments provide for particle physics in the coming decade and beyond.

The $I$ = 1/2 and 3/2 $K-\pi$ scattering length with domain wall fermions at physical pion mass with all-to-all propagators
/ Asmussen, Nils (Southampton U.) ; Erben, Felix (Piemonte Orientale U., Alessandria ; INFN, Turin) ; Flynn, Jonathan (Southampton U.) ; Jüttner, Andreas (Southampton U. ; CERN) ; Mukherjee, Rajnandini (Southampton U.) ; Sachrajda, Christopher T. (Southampton U.)
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. [...]

Simulating rare kaon decays $K^{+}\to\pi^{+}\ell^{+}\ell^{-}$ using domain wall lattice QCD with physical light quark masses
/ Boyle, P.A. (Edinburgh U. ; Brookhaven) ; Erben, F. (Edinburgh U.) ; Flynn, J.M. (Southampton U. ; U. Southampton (main)) ; Gülpers, V. (Edinburgh U.) ; Hill, R.C.

(Edinburgh U.) ; Sachrajda, C.T. (Southampton U.)
/RBC Collaboration ; UKQCD Collaboration
We report the first calculation using physical light-quark masses of the electromagnetic form factor $V(z)$ describing the long-distance contributions to the $K^+\to\pi^+\ell^+\ell^-$ decay amplitude. The calculation is performed on a 2+1 flavor domain wall fermion ensemble with inverse lattice spacing $a^{-1}=1.730(4)$GeV. [...]

Lattice determination of $I= 0$ and 2 $\pi\pi$ scattering phase shifts with a physical pion mass
/ RBC Collaboration
Phase shifts for $s$-wave $\pi\pi$ scattering in both the $I=0$ and $I=2$ channels are determined from a lattice QCD calculation performed on 741 gauge configurations obeying G-parity boundary conditions with a physical pion mass and lattice size of $32^3\times 64$. These results support our recent study of direct CP violation in $K\to\pi\pi$ decay \cite{Abbott:2020hxn}, improving our earlier 2015 calculation \cite{Bai:2015nea}. [...]

Real photon emissions leptonic decays
/ Martinelli, Guido (INFN, Rome ; Rome U.) ; Di Carlo, M (INFN, Rome ; Rome U.) ; Mazzetti, F (INFN, Rome ; Rome U.) ; de Divitiis, G M (Rome U., Tor Vergata ; INFN, Rome2) ; Desiderio, A (Rome U., Tor Vergata ; INFN, Rome2) ; Frezzotti, R (Rome U., Tor Vergata ; INFN, Rome2) ; Garofalo, M (Rome U., Tor Vergata ; INFN, Rome2) ; Hansen, M (Rome U., Tor Vergata ; INFN, Rome2) ; Tantalo, N (Rome U., Tor Vergata ; INFN, Rome2) ; Giusti, D (Rome III U. ; INFN, Rome3) et al.
We present a non-perturbative calculation of the form factors which contribute to the amplitudes for the radiative decays $P\to \ell \bar \nu_\ell \gamma$, where $P$ is a pseudoscalar meson and $\ell$ is a charged lepton. Together with the non-perturbative determination of the virtual photon corrections to the processes $P\to \ell \bar \nu_\ell$, this will allow accurate predictions to be made at $O(\alpha_{em})$ for leptonic decay rates for pseudoscalar mesons ranging from the pion to the $B$ meson.

Non-perturbative renormalization in QCD+QED and its applications to weak decays
/ Di Carlo, Matteo (Rome U. ; INFN, Rome) ; Martinelli, Guido (Rome U. ; INFN, Rome) ; Giusti, Davide (Rome III U. ; INFM, Trieste) ; Lubicz, Vittorio (Rome III U. ; INFN, Rome3) ; Sachrajda, Christopher T. (Southampton U.) ; Sanfilippo, Francesco (INFN, Rome3) ; Simula, Silvano (INFN, Rome3) ; Tantalo, Nazario (Rome U., Tor Vergata ; INFN, Rome2)
We present a novel strategy to renormalize lattice operators in QCD+QED, including first order QED corrections to the non-perturbative evaluation of QCD renormalization constants. Our procedure takes systematically into account the mixed non-factorizable QCD+QED effects which were neglected in previous calculations, thus significantly reducing the systematic uncertainty on renormalization corrections.

Radiative corrections to semileptonic decay rates

We discuss the theoretical framework required for the computation of radiative corrections to semileptonic decay rates in lattice simulations, and in particular to those for $K_{\ell3}$ decays. This is an extension of the framework we have developed and successfully implemented for leptonic decays. [...]

Electromagnetic Corrections to Hadronic Decays from Lattice QCD
/ Lubicz, V (Rome III U. ; INFN, Rome3) ; Martinelli, G (INFN, Rome3 ; INFN, Rome ; CERN) ; Sachrajda, C T (Southampton U.) ; Sanfilippo, F (Southampton U.) ; Simula, S (INFN, Rome2 ; Rome U., Tor Vergata) ; Tantalo, N (Unlisted)
A new method, recently introduced for the lattice calculation of electromagnetic and isospin corrections to weak decays [1], is discussed. Using this method, for the first time, the electromagnetic effects in the leptonic decay rates $π^− \to µ ^− \bar{ν}_µ$ and $K^− \to µ^− \bar{ν}_µ$ have been evaluated in lattice QCD. [...]

The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,062 new measurements from 721 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. [...]
