Lattice Input on the Inclusive Decay Puzzle
P. A. Boyle, L. Del Debbio, N. Garron +4
Recent analyses of flavor-breaking hadronic--decay-based sum rules produce values of low compared to 3-family unitarity expectations. An unresolved…
From a Combined NNLO Lattice, Continuum Analysis of the Light Quark V-A Correlator
P. A. Boyle, L. Del Debbio, N. Garron +4
A combination of lattice and continuum data for the light-quark V-A correlator, supplemented by results from a chiral sum-rule analysis of the flavor-breaking flavor - V-A…
Kaon Mixing Beyond the Standard Model
A. T. Lytle, P. A. Boyle, N. Garron +2
We report on an ongoing calculation of hadronic matrix elements needed to parameterize K-Kbar mixing in generic BSM scenarios, using domain wall fermions (DWF) at two lattice spaci…
A note on Rome-Southampton Renormalization with Smeared Gauge Fields
R. Arthur, P. A. Boyle, S. Hashimoto +1
We have calculated continuum limit step scaling functions of bilinear and four-fermion operators renormalized in a Rome-Southampton scheme using various smearing prescriptions for…
New results from the lattice on the theoretical inputs to the hadronic tau determination of V_us
P. A. Boyle, L. Del Debbio, N. Garron +4
Recent sum rule determinations of |V_us|, employing flavor-breaking combinations of hadronic tau decay data, are significantly lower than either expectations based on 3-family unit…
Some continuum physics results from the lattice V-A correlator
P. A. Boyle, L. Del Debbio, N. Garron +4
We present preliminary results on extractions of the chiral LECs L_10 and C_87 and constraints on the excited pseudoscalar state pi(1300) and pi(1800) decay constants obtained from…
