Successes and Failures of a More Comprehensive Hard Wall AdS/QCD

Understand

We explore corrections to the "hard wall" gravity dual of QCD with two-form tensor fields.

• These fields correspond to a dimension three quark bilinear in QCD, which generates states with 1(--) and 1(+-) quantum numbers, or omega/rho-like and h1/b1-like mesons, respectively.
• We include new interaction terms, which render the model complete up to dimension six.
• We find that breaking chiral symmetry induces modifications to the spectrum, by mixing the vector current and the new two-tensor operator.
