Towards a nonperturbative construction of the -matrix
Brian Henning, Hitoshi Murayama, Francesco Riva +2
We present a nonperturbative recipe for directly computing the -matrix in strongly-coupled QFTs. The method makes use of spectral data obtained in a Hamiltonian framework and ca…
Outer Automorphism Anomalies
Brian Henning, Xiaochuan Lu, Tom Melia +1
We discuss anomalies associated with outer automorphisms in gauge theories based on classical groups, namely charge conjugations for and parities for . We emphasize…
Conformal-helicity duality & the Hilbert space of free CFTs
Brian Henning, Tom Melia
We identify a means to explicitly construct primary operators of free conformal field theories (CFTs) in spacetime dimensions , and . Working in momentum space with spin…
Operator bases, -matrices, and their partition functions
Brian Henning, Xiaochuan Lu, Tom Melia +1
Relativistic quantum systems that admit scattering experiments are quantitatively described by effective field theories, where -matrix kinematics and symmetry considerations are…
Hilbert series and operator bases with derivatives in effective field theories
Brian Henning, Xiaochuan Lu, Tom Melia +1
We introduce a systematic framework for counting and finding independent operators in effective field theories, taking into account the redundancies associated with use of the clas…
