Title: Flavor quarks in AdS{sub 4} and gauge/gravity correspondence

Abstract

The nonperturbative properties of gauge theories in AdS{sub 4} are studied in dual supergravity by including light flavor quarks, which are introduced by a D7-brane embedding. Contrary to the Minkowski and dS{sub 4}, the dilaton does not play any important dynamical role in the AdS{sub 4} case, and the characteristic properties like quark confinement and chiral symmetry breaking are realized mainly due to the geometry AdS{sub 4}. The possible hadron spectra are also examined, and we find that the meson spectra are well described by the formula given by the field theory in AdS{sub 4}, but the characteristic mass scale is modified by the gauge interactions for excited states.
