Expectation value of composite field T anti-T in two-dimensional quantum field theory
Jan, 2004Citations per year
Abstract:
I show that the expectation value of the composite field , built from the components of the energy-momentum tensor, is expressed exactly through the expectation value of the energy-momentum tensor itself. The relation is derived in two-dimensional quantum field theory under broad assumptions, and does not require integrability.- dimension: 2
- operator: composite
- operator product expansion
- tensor: energy-momentum
