The charm quark’s mass in quenched QCD
نویسندگان
چکیده
We present our preliminary result for the charmed quark mass, which follows from taking the Ds and K meson masses from experiment and r0 = 0.5 fm (or, equivalently FK = 160 MeV) to set the scale. For the renormalization group invariant quark mass we obtain Mc = 1684(64) MeV, which translates to mc(mc) = 1314(40)(20)(7) MeV for the running mass in the MS scheme. Renormalization is treated non-perturbatively, and the continuum limit has been taken, so that the only uncontrolled systematic error consists in the use of the quenched approximation.

A precise determination of the charm quark’s mass in quenched QCD
We present a lattice determination of the charm quark’s mass, using the mass of the Ds meson as experimental input. All errors are under control with the exception of the quenched approximation. Setting the scale with FK = 160MeV, our final result for the renormalization group invariant (RGI) quark mass is Mc = 1.654(45)GeV, which translates to mMS c (mc) = 1.301(34)GeV for the running mass in ...

We compute the mass of the charm quark using both quenched and dynamical lattice QCD calculations. We examine the effects of mass dependent lattice artifacts by comparing two different formalisms for the heavy quarks. We take the continuum limit of the charm mass in quenched QCD by extrapolating from three different lattice spacings. At a fixed lattice spacing, the mass of the charm quark is co...

where γ0 = 4. The lattice mass M and, by implication, C0 = C0(M) are specified below. Eq. (1) omits higher orders in the gauge coupling α and power-law artifacts. This paper determines the charm quark’s mass, m̄ch, from quenched calculations of the c̄c spectrum. To anticipate the main sources of uncertainty, let us recall recent determinations the average of the up and down quarks’ masses [1,2]. ...

We determine the mass of the charm quark (mc) from lattice QCD with two flavors of dynamical quarks with a mass around the strange quark. We compare this to a determination in quenched QCD which has the same lattice spacing (0.1 fm). We investigate different formulations of the quark mass, based on the Vector Ward Identity, PCAC relation and the FNAL heavy quark formalism. Based on these prelim...
