Potential Models and Lattice Gauge CurrentCurrent Correlators
Abstract
We compare currentcurrent correlators in lattice gauge calculations with correlators in different potential models for a pseudoscalar charmonium in the quarkgluon plasma. An important ingredient in the evaluation of the currentcurrent correlator in the potential model is the basic principle that, out of the set of continuum states, only resonance states and Gamow states with lifetimes of sufficient magnitudes can propagate as composite objects and can contribute to the currentcurrent correlator. When the contributions from the bound states and continuum states are properly treated, the potential model currentcurrent correlators obtained with the potential proposed by Wong [Phys. Rev. C 72, 034906 (2005)] are consistent with the lattice gauge correlators. The proposed potential model thus gains support to be a useful tool to complement lattice gauge calculations for the study of QQ{bar} states at high temperatures.

We compare currentcurrent correlators in lattice gauge calculations with correlators in different potential models, for a pseudoscalar charmonium in the quarkgluon plasma. An important ingredient in the evaluation of the currentcurrent correlator in the potential model is the basic principle that, out of the set of continuum states, only resonance states and Gamow states with lifetimes of sufficient magnitudes can propagate as composite objects and can contribute to the currentcurrent correlator. When the contributions from the bound states and continuum states are properly treated, the potential model currentcurrent correlators obtained with the potential proposed by Wong [Phys. Rev.

Potential models and lattice correlators for quarkonia at finite temperature
We update our recent calculation of quarkonium Euclidean correlators at finite temperatures in a potential model by including the effect of zero modes in the lattice spectral functions. These contributions cure most of the previously observed discrepancies with lattice calculations, supporting the use of potential models at finite temperature as an important tool to complement lattice studies. 
Highprecision charmquark mass and QCD coupling from currentcurrent correlators in lattice and continuum QCD
We use lattice QCD simulations, with MILC gluon configurations and HISQ cquark propagators, to make very precise determinations of moments of charmquark pseudoscalar, vector and axialvector correlators. These moments are combined with new fourloop results from continuum perturbation theory to obtain several new determinations of the MS mass of the charm quark and of the MS coupling. We find m{sub c}(3 GeV)=0.986(10) GeV, or, equivalently, m{sub c}(m{sub c})=1.268(9) GeV, both for n{sub f}=4 flavors; and {alpha}{sub MS}(3 GeV,n{sub f}=4)=0.251(6), or, equivalently, {alpha}{sub MS}(M{sub Z},n{sub f}=5)=0.1174(12). The new mass agrees well with results from continuum analyses of the vector correlator usingmore » 
Highprecision c and b masses, and QCD coupling from currentcurrent correlators in lattice and continuum QCD
We extend our earlier latticeQCD analysis of heavyquark correlators to smaller lattice spacings and larger masses to obtain new values for the c mass and QCD coupling, and, for the first time, values for the b mass: m{sub c}(3 GeV,n{sub f}=4)=0.986(6) GeV, {alpha}{sub MS}(M{sub Z},n{sub f}=5)=0.1183(7), and m{sub b}(10 GeV,n{sub f}=5)=3.617(25) GeV. These are among the most accurate determinations by any method. We check our results using a nonperturbative determination of the mass ratio m{sub b}({mu},n{sub f})/m{sub c}({mu},n{sub f}); the two methods agree to within our 1% errors and taken together imply m{sub b}/m{sub c}=4.51(4). We also update our previousmore »
