DESCRIPTION:Speakers: Christopher Sachrajda (Uni. Southampton)\n\nLattice 
 QCD results for some physical quantities are now so precise that isospin-b
 reaking effects\, including in particular QED corrections\, need to be inc
 luded to make further progress in precision tests of the Standard Model an
 d in determining CKM matrix elements. I will review the current status of 
 including QED corrections in finite-volume Euclidean lattice computations 
 and discuss the “Cabibbo Angle Anomaly”\, the tension in the unitarity
  of the first row of the CKM matrix.\nAn important related class of proces
 ses are the radiative decays of pseudoscalar mesons\, $P\\to\\ell\\nu_\\el
 l\\gamma$ and $P\\to\\ell\\nu_\\ell(\\ell^{+\\prime} \\ell^{-\\prime})$. 
 I will review the latest lattice predictions and compare them to experimen
 tal results from the KLOE(Frascati)\, E36(JPARC) and NA62(CERN) collaborat
 ions.\nNovel techniques implemented in the above studies include “Infini
 te-Volume Reconstruction” and “Spectral Function Reconstruction”.\n\
