Journal ArticleDOI
An exploratory lattice study of Delta I=3/2 K ->pi pi decays at next-to-leading order in the chiral expansion
Philippe Boucaud,V. Gimenez,C.-J. David Lin,Vittorio Lubicz,Guido Martinelli,Mauro Papinutto,Christopher T. Sachrajda +6 more
TL;DR: In this paper, a direct evaluation of Δ I = 3 / 2 K → π π matrix elements with the aim of determining all the low-energy constants at NLO in the chiral expansion is presented.
Journal ArticleDOI
The invisible renormalon
TL;DR: In this article, the structure of renormalons in the heavy quark effective theory was studied by expanding the propagator in powers of 1/m Q, and it was shown that the way in which the leading ultraviolet renormalon appeared depends on the regularization scheme used to define the effective theory.
Journal ArticleDOI
Renormalons and the Heavy Quark Effective Theory
TL;DR: In this article, a nonperturbative method for defining the higher dimensional operators which appear in the Heavy Quark Effective Theory (HQET), such that their matrix elements are free of renormalon singularities, and diverge at most logarithmically with the ultra-violet cut-off, is proposed.
Journal ArticleDOI
Finite-Volume Two-Pion Amplitudes in the I=0 Channel
C.-J.D. Lin,Guido Martinelli,Elisabetta Pallante,Christopher T. Sachrajda,Giovanni Villadoro +4 more
TL;DR: In this article, the two-pion matrix elements and correlation functions of an I = 0 scalar operator were computed in finite and infinite volumes for both full and quenched QCD.
