Onium Masses with Three Flavors of Dynamical Quarks
نویسندگان
چکیده
We have greatly extended an earlier calculation of the charmonium spectrum on three flavor dy-namical quark ensembles by using more recent ensembles generated by the MILC collaboration. The heavy quarks are treated using the Fermilab formulation. The charmonium state masses are in reasonable agreement with the observed spectrum; however, some of the spin splittings may still be too small. c Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.

متن کاملDynamical quark effects on light quark masses
Light quark masses are calculated in lattice QCD with two degenerate flavors of dynamical quarks. The calculations are made with improved actions with lattice spacing a = 0.22-0.11 fm. In the continuum limit we find m(M&Smacr;)(ud)(2 GeV) = 3.44(+0.14)(-0.22) MeV using the pi and rho meson masses as physical input, and m(M&Smacr;)(s)(2 GeV) = 88(+4)(-6) MeV or 90(+5)(-11) MeV with the K or stra...
متن کاملOn Mass Spectrum in SQCD. Unequal quark masses
N = 1 SQCD with Nc colors and two types of light quarks, Nl flavors with smaller masses ml and Nh = NF−Nl flavors with larger masses mh , Nc < NF < 3Nc , 0 < ml ≤ mh ≪ ΛQ , is considered within the dynamical scenario in which quarks can form the coherent colorless diquark-condensate. There are several phase states at different values of parameters r = ml/mh , Nl , and NF . Properties of these p...
متن کاملHybrid Monte Carlo algorithm for lattice QCD with two flavors of dynamical Ginsparg-Wilson quarks
We study aspects concerning numerical simulations of Lattice QCD with two flavors of dynamical Ginsparg-Wilson quarks with degenerate masses. A Hybrid Monte Carlo algorithm is described and the formula for the fermionic force is derived for two specific implementations. The implementation with optimal rational approximation method is favored both in CPU time and memory consumption.
متن کاملHeavy baryon mass spectrum from lattice QCD with 2+1 flavors
We study the heavy baryon mass spectrum on gauge configurations that include 2+1 flavors of dynamical improved staggered quarks. A valence clover heavy quark is combined with two improved staggered light quark propagators to form baryons with different flavors. We are using MILC coarse gauge configurations with a lattice spacing of about 0.12 fm. In this preliminary investigation, we explore th...
