Light quark masses from scalar sum rules
In this work, the mass of the strange quark is calculated from QCD sum rules for the divergence of the strangeness-changing vector current. The phenomenological scalar spectral function which enters the sum rule is determined from our previous work on strangeness-changing scalar form factors [1]. For the running strange mass in the MS scheme, we find ms(2GeV) = 99 ± 16 MeV. Making use of this r...
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 کاملQCD Sum-Rule Bounds on the Light Quark Masses
QCD sum-rules are related to an integral of a hadronic spectral function, and hence must satisfy integral inequalities which follow from positivity of the spectral function. Development of these Hölder inequalities and their application to the Laplace sum-rule for pions lead to a lower bound on the average of the non-strange 2GeV light-quark masses in the MS scheme. The light quark masses are f...
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 کاملHeavy quark masses from QCD sum rules
I review recent determinations of the (on-shell) charmand beauty-quark masses in the framework of relativistic and non-relativistic ratios of Laplace transform QCD moment sum rules. The validity of the non-relativistic version of QCD sum rules in this particular application is discussed. Invited talk at the Mexican School of Particles and Fields, Villahermosa, Mexico, October 1994. John Simon G...
