Discovery of multiple p-mode pulsation frequencies in the roAp star, HD 86181
Fangfei Shi, Donald W. Kurtz, Daniel L. Holdsworth +5
We report the frequency analysis of a known roAp star, HD 86181 (TIC 469246567), with new inferences from TESS data. We derive the rotation frequency to be = 0.48753 $\pm…
Hoelder Inequalities and Isospin Splitting of the Quark Scalar Mesons
Fang Shi, T. G. Steele, V. Elias +3
A Hoelder inequality analysis of the QCD Laplace sum-rule which probes the non-strange (n\bar n) components of the I={0,1} (light-quark) scalar mesons supports the methodological c…
QCD Sum-Rule Invisibility of the sigma Meson
T. G. Steele, Fang Shi, V. Elias
QCD Laplace sum-rules for light-quark I=0,1 scalar currents are used to investigate candidates for the lightest scalar mesons. The theoretical predictions for the sum-rul…
QCD Sum-Rule Consistency of Lowest-Lying Quark Scalar Resonances
V. Elias, A. H. Fariborz, Fang Shi +1
We investigate lowest-lying scalar meson properties predicted from QCD Laplace sum rules based upon isovector and isoscalar non-strange currents. The hadronic content of…
Direct Single Instanton Contributions to Finite Energy Sum Rules
A. S. Deakin, V. Elias, N. H. Fuchs +3
Instanton contributions to pseudoscalar finite-energy sum rules are extracted from the explicit single-instanton contribution to the pseudoscalar Laplace sum rule in the instanton…
Broad Sub-Continuum Resonances and the Case for Finite-Energy Sum-Rules
A. S. Deakin, V. Elias, A. H. Fariborz +3
There is a need to go beyond the narrow resonance approximation for QCD sum-rule channels which are likely to exhibit sensitivity to broad resonance structures. We first discuss ho…
QCD Sum Rules and the Lowest-Lying I=0 Scalar Resonance
V. Elias, A. H. Fariborz, Fang Shi +1
A QCD Laplace sum rule framework is employed to investigate the relationship between the mass and the decay width of the sigma, the lowest-lying isoscalar resonance in the spin-zer…
Beyond the Narrow Resonance Approximation: Decay Constant and Width of the First Pion-Excitation State
V. Elias, A. H. Fariborz, M. A. Samuel +2
We consider the first pion excitation as a sub-continuum resonance in the pseudoscalar channel, and we obtain parameters characterizing this resonance through a global fit of the B…
