Tensor Mesons in AdS / QCD

  title={Tensor Mesons in AdS / QCD},
  author={Emanuel Katz and Adam Lewandowski and Matthew D. Schwartz},
We explore tensor mesons in AdS/QCD focusing on f2(1270), the lightest spin-two resonance in QCD. We find that the f2 mass and the partial width Γ(f2 → γγ) are in very good agreement with data. In fact, the dimensionless ratio of these two quantities comes out within the current experimental bound. The result for this ratio depends only on Nc and Nf , and the quark and glueball content of the operator responsible for the f2; more importantly, it does not depend on chiral symmetry breaking and… CONTINUE READING
