Sturm (The RBC and UKQCD Collaborations) We describe the computation of the amplitude A 2 for a kaon to decay into two pions with isospin I =2. The results presented in [ T. Blum et al. Phys. Rev. Lett. 108 141601 (2012) ] from an analysis of 63 gluon configurations are updated to 146 configurations giving Re A 2 =1.381(46) stat (258) syst 10 -8 Ge... [Phys. Rev.
