Electromagnetic effects on the light pseudoscalar mesons and determination of $m_u/m_d$

Autor: MILC Collaboration, Basak, S., Bazavov, A., Bernard, C., DeTar, C., Freeland, E., Foley, J., Gottlieb, Steven, Heller, U. M., Komijani, J., Laiho, J., Levkova, L., Osborn, J., Sugar, R. L., Torok, A., Toussaint, D., Van de Water, R. S., Zhou, R.

The MILC Collaboration has completed production running of electromagnetic effects on light mesons using asqtad improved staggered quarks. In these calculations, we use quenched photons in the noncompact formalism. We study four lattice spacings from

Electromagnetic effects on the light hadron spectrum

Autor: MILC Collaboration, Basak, S., Bazavov, A., Bernard, C., DeTar, C., Freeland, E., Foley, J., Gottlieb, Steven, Heller, U. M., Komijani, J., Laiho, J., Levkova, L., Li, R., Osborn, J., Sugar, R. L., Torok, A., Toussaint, D., Van de Water, R. S., Zhou, R.

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 suffices to NLO in XPT. That is, the sea quarks are electrically neutral, wh

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

Publikováno v: Phys. Rev. D 93, 025026 (2016)

We compute the form factors for the $B \to Kl^+l^-$ semileptonic decay process in lattice QCD using gauge-field ensembles with 2+1 flavors of sea quark, generated by the MILC Collaboration. The ensembles span lattice spacings from 0.12 to 0.045 fm an

$|V_{ub}|$ from $B\to\pi\ell\nu$ decays and (2+1)-flavor lattice QCD

Publikováno v: Phys. Rev. D 92, 014024 (2015)

We present a lattice-QCD calculation of the $B\to\pi\ell\nu$ semileptonic form factors and a new determination of the CKM matrix element $|V_{ub}|$. We use the MILC asqtad 2+1-flavor lattice configurations at four lattice spacings and light-quark mas

The $B \to D \ell \nu$ form factors at nonzero recoil and $|V_{cb}|$ from $2+1$-flavor lattice QCD

Publikováno v: Phys. Rev. D 92, 034506 (2015)

We present the first unquenched lattice-QCD calculation of the hadronic form factors for the exclusive decay $\overline{B} \rightarrow D \ell \overline{\nu}$ at nonzero recoil. We carry out numerical simulations on fourteen ensembles of gauge-field c

Gradient flow and scale setting on MILC HISQ ensembles

Autor: MILC Collaboration, Bazavov, A., Bernard, C., Brown, N., DeTar, C., Foley, J., Gottlieb, Steven, Heller, U. M., Komijani, J., Laiho, J., Levkova, L., Sugar, R. L., Toussaint, D., Van de Water, R. S.

Publikováno v: Phys. Rev. D 93, 094510 (2016)

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 include four lattice spacings, ranging from approximately 0.15 to 0.06 fm

$B\to\pi\ell\nu$ semileptonic form factors from unquenched lattice QCD and determination of $|V_{ub}|$

Publikováno v: PoS(LATTICE 2014)385

We compute the $B\to\pi\ell\nu$ semileptonic form factors and update the determination of the CKM matrix element $|V_{ub}|$. We use the MILC asqtad ensembles with $N_f=2+1$ sea quarks at four different lattice spacings in the range $a \approx 0.045$~

Charmed and light pseudoscalar meson decay constants from HISQ simulations

We compute the leptonic decay constants $f_{D^+}$, $f_{D_s}$, and $f_{K^+}$, and the quark-mass ratios $m_c/m_s$ and $m_s/m_l$ in unquenched lattice QCD. We use the MILC highly improved staggered quark (HISQ) ensembles with four dynamical quark flavo

Gradient Flow Analysis on MILC HISQ Ensembles

Autor: Bazavov, A., Bernard, C., Brown, N., DeTar, C., Foley, J., Gottlieb, Steven, Heller, U. M., Hetrick, J. E., Komijani, J., Laiho, J., Levkova, L., Oktay, M., Sugar, R. L., Toussaint, D., Van de Water, R. S., Zhou, R.

We report on a preliminary scale determination with gradient-flow techniques on the $N_f = 2 + 1 + 1$ HISQ ensembles generated by the MILC collaboration. The ensembles include four lattice spacings, ranging from 0.15 to 0.06 fm, and both physical and
