Two-Photon and Two-gluon Decays of and P-wave Heavy Quarkonium States
T. N. Pham
By neglecting the relative quark momenta in the propagator term, the two-photon and two-gluon decay amplitude of heavy quarkonia states can be written as a local heavy quark field…
Nonleptonic to charmonium decays: analyses in pursuit of determining the weak phase
Pietro Colangelo, Fulvia De Fazio, Wei Wang
We analyze nonleptonic decays to a charmonium state and a light meson, induced by the transition, which are useful to access the - mixing…
Holography, Heavy-Quark Free Energy, and the QCD Phase Diagram
Pietro Colangelo, Floriana Giannuzzi, Stefano Nicotri
We use gauge/string duality to investigate the free energy of two static color sources (a heavy quark-antiquark pair) in a Yang-Mills theory in strongly interacting matter, varying…
form factors and decays into
Pietro Colangelo, Fulvia De Fazio, Wei Wang
We compute the transition form factors using light-cone QCD sum rules at leading order in the strong coupling constant, and also including an estimate of next-to-…
Open charm meson spectroscopy: Where to place the latest piece of the puzzle
Pietro Colangelo, Fulvia De Fazio
We discuss how to classify the meson recently discovered by the BaBar Collaboration. We consider four possible assignments, together with signatures usef…
