Electromagnetic Mass Difference of Heavy Mesons
P. Colangelo, M. Ladisa, G. Nardulli +1
Using the Cottingham formula, we give an estimate of the electromagnetic mass splitting of pseudoscalar heavy mesons in the beauty and charm sector. We include in the dispersion re…
QCD Interactions of Heavy Mesons with Pions by Light-Cone Sum Rules
P. Colangelo, F. De Fazio
Light-cone QCD sum rules are employed to compute the strong coupling constants: g_{B^* B^* pi}, g_{B_1 B_0 pi} and g_{B_1 B^* pi}, where (B,B^*) and (B_0,B_1) are negative and posi…
Violations of Local Duality in the Heavy Quark Sector
P. Colangelo, C. A. Dominguez, G. Nardulli
We examine the origin of possible failures of the quark-hadron local duality. In particular, we consider a correlator of two currents comprising heavy quark operators, and compare…
On the QCD Sum Rule Determination of the Strange Quark Mass
P. Colangelo, F. De Fazio, G. Nardulli +1
In the QCD Sum Rule determination of using the two-point correlator of divergences of vector currents, the final uncertainty on is mainly due to the hadronic spe…
