Variance reduction with practical all-to-all lattice propagators
Eric Endress, Carlos Pena, Karthee Sivalingam
We discuss all-to-all quark propagator techniques in two (related) contexts within Lattice QCD: the computation of closed quark propagators, and applications to the so-called "eye…
Exploring the role of the charm quark in the rule
Eric Endress, Carlos Pena
We study the dependence on the charm quark mass of the leading-order low-energy constants of the effective Hamiltonian, with the aim of elucidating the role of the charm mas…
Contribution of the charm quark to the ΔI=1/2 rule
Eric Endress, Carlos Pena
We report on the progress of our ongoing project to quantify the role of the charm quark in the non-leptonic decay of a kaon into two pions. The effect of its associated mass scale…
Variance reduction techniques for a quantitative understanding of the ΔI = 1/2 rule
Eric Endress, Carlos Pena
The role of the charm quark in the dynamics underlying the ΔI = 1/2 rule for kaon decays can be understood by studying the dependence of kaon decay amplitudes on the charm quark ma…
On the efficiency of stochastic volume sources for the determination of light meson masses
E. Endress, A. Jüttner, H. Wittig
We investigate the efficiency of single timeslice stochastic sources for the calculation of light meson masses on the lattice as one varies the quark mass. Simulations are carried…
Mesonic and baryonic correlation functions at fine lattice spacings
S. Capitani, M. Della Morte, E. Endress +4
We report on our on-going project to compute mesonic and baryonic two- and three-point correlation functions in simulations using Nf=2 flavours of O(a) improved Wilson quarks and t…
