An exploratory lattice study of DI=3/2 K -> pi pi decays at next-to-leading order in the chiral expansion

P. Boucaud, V. Gimenez, C-J. D. Lin +4

We present the first direct evaluation of DI = 3/2 K -> pi pi matrix elements with the aim of determining all the low-energy constants at NLO in the chiral expansion. Our numerical…
