Rigorous Limits on the Interaction Strength in Quantum Field Theory

Francesco Caracciolo, Slava Rychkov

We derive model-independent, universal upper bounds on the Operator Product Expansion (OPE) coefficients in unitary 4-dimensional Conformal Field Theories. The method uses the conf…

Energy's and amplitudes' positivity

Alberto Nicolis, Riccardo Rattazzi, Enrico Trincherini

In QFT, the null energy condition (NEC) for a classical field configuration is usually associated with that configuration's stability against small perturbations, and with the sub-…

Chiral symmetry breaking and theta vacuum structure in QCD

G. Morchio, F. Strocchi

The solution of the axial U(1) problem, the role of the topology of the gauge group in forcing the breaking of axial symmetry in any irreducible representation of the observable al…

Universal Constraints on Conformal Operator Dimensions

Vyacheslav S. Rychkov, Alessandro Vichi

We continue the study of model-independent constraints on the unitary Conformal Field Theories in 4-Dimensions, initiated in arXiv:0807.0004. Our main result is an improved upper b…

Unconstrained Higher Spins of Mixed Symmetry. II. Fermi Fields

Andrea Campoleoni, Dario Francia, Jihad Mourad +1

This paper is a sequel of arXiv:0810.4350 [hep-th], and is also devoted to the local "metric-like" unconstrained Lagrangians and field equations for higher-spin fields of mixed sym…
