Non-perturbative renormalization and running of Delta F=2 four-fermion operators in the SF scheme
Mauro Papinutto, Carlos Pena, David Preti
We present preliminary results of a non-perturbative study of the scale-dependent renormalization constants of a complete basis of Delta F=2 parity-odd four-fermion operators that…
A braid model for the particle X(3872)
C. Peña, L. Jacak
The Model of Quark Exchange (MQE) describes the particle X(3872) as a meson molecule. We asked whether braids influence the meson potential in the MQE. We used the Burau representa…
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…
