Abstract: (Springer)
We reduce 2L-point functions of vector fields into two-point functions of tensor fields by multiply applying operator product expansions. Anomalous dimensions are computed for irreducible tensor fields with Young frames of two rows andL blocks.L is arbitrary.- sigma model: nonlinear
- symmetry: O(N)
- dimension: 2-4
- n-point function
- operator product expansion
- expansion 1/N
- field theory: tensor
- anomaly
