Quark mass dependence of pseudoscalar masses and decay constants on a lattice
Our previous calculations of the seaand valence-quark mass dependence of the pseudoscalar meson masses and decay constants is repeated on a 163 · 32 lattice which allows for a better determination of the quantities in question. The conclusions are similar as before on the 164 lattice [1]. The two light dynamical quark flavours we simulate have masses in the range 1 4ms < mu,d < 2 3ms. The sea q...
متن کاملLight pseudoscalar decay constants , quark masses , and low energy constants from three - flavor lattice QCD
As part of our program of lattice simulations of three flavor QCDwith improved staggered quarks, we have calculated pseudoscalar meson masses and decay constants for a range of valence quark masses and sea quark masses on lattices with lattice spacings of about 0.125 fm and 0.09 fm. We fit the lattice data to forms computed with “staggered chiral perturbation theory.” Our results provide a sens...
متن کاملQuark Masses on the Lattice: Light and Heavy
I review the current status of lattice calculations of light and heavy quark masses. Significant progresses, in these studies, have been allowed by the introduction of improved actions and non-perturbative renormalization techniques. Current determinations of light quark masses are accurate at the level of 20%, where the main source of uncertainty is represented by the quenching error. The dete...
متن کاملLandscape Predictions for the Higgs Boson and Top Quark Masses
If the Standard Model is valid up to scales near the Planck mass, and if the cosmological constant and Higgs mass parameters scan on a landscape of vacua, it is well-known that the observed orders of magnitude of these quantities can be understood from environmental selection for large scale structure and atoms. If in addition the Higgs quartic coupling scans, with a probability distribution pe...
متن کاملFixing the Top-Quark and Higgs-Boson Masses
If the quadratic divergence of the standard electroweak model and its local variation with mass scale are both assumed to be zero, then a modified one-loop calculation yields mt ≃ 117 GeV and mH ≃ 183 GeV . Such a scenario may be the result of an underlying theory to be revealed at a much higher mass scale. The standard SU(2) X U(1) electroweak gauge model has a fundamental scalar doublet Φ = (...
