OPE, Heavy-Quark Mass, and Heavy-Meson Decay Constants from QCD Sum Rules
OPE Heavy-Quark Mass Heavy-Meson Decay Constants
2011/1/7
We present a sum-rule extraction of the decay constants of heavy-light mesons from the two-point correlator of pseudoscalar currents. To this end, we compare the perturbative expansions for the correl...

Heavy-Quark Mass Heavy-Meson Decay Constants
2011/1/7
We present a sum-rule extraction of heavy-meson decay constants from the two-point correlator of heavy-light pseudoscalar currents. Our main concern is to control the uncertainties of the decay consta...

Analysis of the coupling constants ga0ηπ0 and ga0η′π0 with light-cone QCD sum rules
a0(980) light-cone QCD sum rules
2009/12/24
In this article, we take the point of view that the light scalar meson a0(980) is a conventional qq state, and calculate the coupling constants ga0ηπ0 and ga0η′π0 with the light-cone QCD sum rules. Th...
Heavy flavor baryon spectra via QCD sum rules
singly heavy baryon doubly heavy baryon triply heavy baryon QCD sum rules
2009/11/24
In this talk, we give a short review of our recent works on studying the singly heavy baryon, doubly heavy baryon, and triply heavy baryon spectra from QCD sum rules.
Rise and Fall of Pentaquarks in the QCD Sum Rules Approach
Mass and decay Pentaquarks QCD Sum Rules
2010/10/13
We review the existing mass and decay width determinations of pentaquarks with QCD Sum Rules (QCDSR). We give special attention to the intermediate assumptions and choices which we are obliged to do i...
