Phenomenology Of The Holographic Soft-Wall Model Of QCD With "Reversed" Dilaton

Abstract

We study the phenomenology of the recently proposed modified version of the Soft-Wall model of holographic QCD with a negative dilaton profile. We investigate vector and scalar mesons, evaluating mass spectra, decay constants and two-point correlation functions. We then study chiral symmetry breaking and compute the coupling of a scalar meson with two pseudoscalars. Finally, we compare the results with the ones found in the literature in the positive-dilaton case.Comment: Latex, 4 pages, talk given at "QCD@Work 2010 - International Workshop on QCD - Theory and Experiment", June 20-23 2010, Martina Franca, Ital
