Abstract
We analyze the holographic description of non-singlet baryons in various backgrounds with reduced supersymmetries and/or confinement. We show that they exist in all AdS5 × Y 5 backgrounds with Y5 an Einstein manifold bearing five form flux, for a number of quarks 5N/8 < k ≤ N , independently on the supersymmetries preserved. This result still holds for γi deformations. In the confining Maldacena-Nuñez background non-singlet baryons also exist, although in this case the interval for the number of quarks is reduced as compared to the conformal case. We generalize these configurations to include a nonvanishing magnetic flux such that a complementary microscopical description can be given in terms of lower dimensional branes expanding into fuzzy baryons. This description is a first step towards exploring the finite ’t Hooft coupling region.
