On the light glueball spectrum in a holographic description of QCD

P. Colangelo; F. De Fazio; F. Jugeau; S. Nicotri

We investigate the spectra of light scalar and vector glueballs in a holografic description of QCD with a dilaton background bulk field. In particular, we study how the glueball masses depend on the conditions on the dilaton background and on the geometry of the bulk.

Nonfactorizable contributions in B decays to charmonium: The case of B − → K − h c

P. Colangelo; F. De Fazio; T. N. Pham

Nonleptonic B to charmonium decays generally show deviations from the factorization predictions. For example, the mode
