Equation of state in (2+1) flavor QCD at high temperatures
Johannes Heinrich Weber, Alexei Bazavov, Peter Petreczky
We calculate the Equation of State at high temperatures in (2+1) flavor QCD using the highly improved staggered quark (HISQ) action. We study the lattice spacing dependence of the…
Disconnected hadronic vacuum polarization contribution to the muon g-2 with HISQ
Shuhei Yamamoto, Carleton DeTar, Aida X. El-Khadra +3
We describe a computation of the contribution to the anomalous magnetic moment of the muon from the disconnected part of the hadronic vacuum polarization. We use the highly-improve…
Splittings of low-lying charmonium masses at the physical point
Carleton DeTar, Andreas S. Kronfeld, Song-haeng Lee +2
We present high-precision results from lattice QCD for the mass splittings of the low-lying charmonium states. For the valence charm quark, the calculation uses Wilson-clover quark…
B- and D-meson leptonic decay constants and quark masses from four-flavor lattice QCD
Fermilab Lattice, MILC, TUMQCD Collaborations +20
We describe a recent lattice-QCD calculation of the leptonic decay constants of heavy-light pseudoscalar mesons containing charm and bottom quarks and of the masses of the up, down…
from decay and four-flavor lattice QCD
A. Bazavov, C. Bernard, C. DeTar +17
Using HISQ MILC ensembles with five different values of the lattice spacing, including four ensembles with physical quark masses, we have performed the most precise com…
Lattice computation of the electromagnetic contributions to kaon and pion masses
S. Basak, A. Bazavov, C. Bernard +12
We present a lattice calculation of the electromagnetic (EM) effects on the masses of light pseudoscalar mesons. The simulations employ 2+1 dynamical flavors of asqtad QCD quarks,…
