Abstract

We explore existing sum rule analyses of the u, d and s quark masses. We argue that certain assumptions about the behavior of unmeasured continuum scalar and pseudoscalar spectral functions can lead to significant overestimates of these masses, and illustrate the source of the problem in the analogous isovector vector channel.

Extraction of light quark masses from sum rule analyses of axial vector and vector current Ward identities

Journal Article Bhattacharya, T; Gupta, R; Maltman, K - Physical Review, D

In light of recent lattice results for the light quark masses m{sub s} and m{sub u}+m{sub d}, we reexamine the use of sum rules in the extraction of these quantities, and discuss a number of potential problems with existing analyses. The most important issue is that of the overall normalization of the hadronic spectral functions relevant to the sum rule analyses. We explain why previous treatments, which fix this normalization by assuming complete resonance dominance of the continuum threshold region, can potentially overestimate the resonance contributions to spectral integrals by factors as large as {approximately}5. We propose an alternate methodmore »« less

D{sub s}(2317) as a four-quark state in QCD sum rules

Journal Article Kim, Hungchong; Oh, Yongseok - Physical Review. D, Particles Fields

We perform a QCD sum-rule study of the open-charmed D{sub s}(2317) as a four-quark state. Using the diquark-antidiquark picture for the four-quark state, we consider four possible interpolating fields for D{sub s}(2317), namely, scalar-scalar, pseudoscalar-pseudoscalar, vector-vector, and axial-vector-axial-vector types. We test all four currents by constructing four separate sum rules. The sum-rule with the scalar-scalar current gives a stable value for the D{sub s} mass which qualitatively agrees with the experimental value, and the result is not sensitive to the continuum threshold. The vector-vector sum rule also gives a stable result with small sensitivity to the continuum threshold and themore »« less

Strange quark mass from e{sup +}e{sup -} revisited and present status of light quark masses

Journal Article Narison, Stephan - Physical Review. D, Particles Fields

We reconsider the determinations of the strange quark mass m{sub s} from e{sup +}e{sup -} into hadrons data using a new combination of finite energy sum rules (FESR) and revisiting the existing {tau}-like sum rules by including nonresonant contributions to the spectral functions. To order {alpha}{sub s}{sup 3} and including the tachyonic gluon mass {lambda}{sup 2} contribution, which phenomenologically parametrizes the UV renormalon effect into the perturbative series, we obtain the invariant mass m-circumflex{sub s}=(119{+-}17) MeV leading to m{sub s}(2 GeV)=(104{+-}15) MeV. Combining this value with the recent and independent phenomenological determinations from some other channels, to order {alpha}{sub s}{supmore »« less

QCD sum rules for the pseudoscalar decay constants: To constrain the strange quark mass

Journal Article Kim, Hungchong - Physical Review D

We study the higher order corrections of quark masses to the Gell-Mann{endash}Oakes{endash}Renner (GOR) relation by constructing QCD sum rules exclusively for pseudoscalar mesons from the axial-vector correlation function, i{integral}d{sup 4}xe{sup ip{dot x}}{l_angle}0{vert_bar}T[A{sub {mu}}(x)A{sub {nu}}(0)]{vert_bar}0{r_angle}. To project out the pseudoscalar meson contributions, we apply {minus}p{sup {mu}}p{sup {nu}}/p{sup 2} to this correlation function and construct sum rules for the decay constants of pseudoscalar mesons, f{sub {pi}},f{sub k}, and f{sub {eta}{sub 8}}. The operator product expansion (OPE) is proportional to quark masses due to PCAC (partial conservation of axial-vector current). To leading order in quark mass, each sum rule reproduces the corresponding GORmore »« less
