$D$ -meson semileptonic form factors at zero momentum transfer in (2+1+1)-flavor lattice QCD

Thomas Primer, Claude Bernard, Carleton DeTar +7

We present a calculation of the $D \to K ℓ ν$ and $D \to π ℓ ν$ semileptonic form factors at $q^{2} = 0$ , which enable determinations of the CKM matrix elements $\lvert{V_{cs}}\rvert…

Decay constants $f_{B}$ and $f_{B_{s}}$ from HISQ simulations

Fermilab Lattice, MILC Collaborations, : +25

We give a progress report on a project aimed at a high-precision calculation of the decay constants $f_{B}$ and $f_{B_{s}}$ from simulations with HISQ heavy and light valence and sea q…

Electromagnetic effects on the light hadron spectrum

MILC Collaboration, S. Basak, A. Bazavov +16

For some time, the MILC Collaboration has been studying electromagnetic effects on light mesons. These calculations use fully dynamical QCD, but only quenched photons, which suffic…

$B \to K l^{+} l^{-}$ decay form factors from three-flavor lattice QCD

Jon A. Bailey, A. Bazavov, C. Bernard +24

We compute the form factors for the $B \to K l^{+} l^{-}$ semileptonic decay process in lattice QCD using gauge-field ensembles with 2+1 flavors of sea quark, generated by the MILC Colla…

The $B \to D ℓ ν$ form factors at nonzero recoil and $∣ V_{c b} ∣$ from $2 + 1$ -flavor lattice QCD

Fermilab Lattice, MILC Collaborations, : +24

We present the first unquenched lattice-QCD calculation of the hadronic form factors for the exclusive decay $B \to D ℓ ν$ at nonzero recoil. We carr…

$∣ V_{u b} ∣$ from $B \to π ℓ ν$ decays and (2+1)-flavor lattice QCD

Fermilab Lattice, MILC Collaborations, : +26

We present a lattice-QCD calculation of the $B \to π ℓ ν$ semileptonic form factors and a new determination of the CKM matrix element $∣ V_{u b} ∣$ . We use the MILC asqtad 2+1-flavor l…

Gradient flow and scale setting on MILC HISQ ensembles

MILC Collaboration, A. Bazavov, C. Bernard +11

We report on a scale determination with gradient-flow techniques on the $N_{f} = 2 + 1 + 1$ highly improved staggered quark ensembles generated by the MILC Collaboration. The ensembles inc…

Painleve Transcendents and PT-Symmetric Hamiltonians

Carl M. Bender, Javad Komijani

Unstable separatrix solutions for the first and second Painlevé transcendents are studied both numerically and analytically. For a fixed initial condition, say $y (0) = 0$ , there is a…
