Résumé |
After a general overview of the S-matrix bootstrap program for large N QCD, I will
describe how to import the microscopic dynamics of the theory by incorporating the
two-point function and pion form factor of the simplest local gauge invariant
operator the electromagnetic current. I will present two conceptually distinct
kinds of bounds: rigorous universal bounds that only rely on UV power counting to
fix the number of subtractions, and more phenomenological bounds that input
asymptotic freedom quantitatively about a chosen cut-off scale. |
