This note complements and clarifies the results obtained in the original paper {\it QCD Parameters Correlations from Heavy Quarkonia} [1] where, here, we present a more detailed di…
Updating m_c,b(m_c,b) from SVZ-Moments and their Ratios
Stephan Narison, LUPM-CNRS-Montpellier
Using recent values of α_s, the gluon condensates <α_s G^2> and <g^3 f_abcG^3> and the new data on the ψ/Υ-families, we update our determinations of the MS-bar running quark masses…
Scalar Meson Contributions to a_μfrom Hadronic Light-by-Light Scattering
M. Knecht, S. Narison, A. Rabemananjara +1
Using an effective σ/f_0(500) resonance, which describes the ππ-->ππand γγ-->ππscattering data, we evaluate its contribution and the ones of the other scalar mesons to the the hadr…
0+ and 1+ heavy-light exotic mesons at N2LO in the chiral limit
R. M Albuquerque, S. Narison, F. Fanomezana +3
We use QCD spectral sum rules (QSSR) and the factorization properties of molecule and four-quark currents to estimate the masses and couplings of the 0+ and 1+ molecules and four-q…
XYZ - SU3 Breakings from Laplace Sum Rule at Higher Orders: Summary
R. Albuquerque, S. Narison, D. Rabetiarivony +1
This talk reviews and summarizes some of our results in [1] on XYZ- SU3 Breakings obtained from QCD Laplace Sum Rules (LSR) at next-to-next-leading order (N2LO) of perturbative (PT…
