Bootstrapping 3D fermions with global symmetries

A bstractWe study the conformal bootstrap for 4-point functions of fermions 〈ψiψjψkψℓ〉 in parity-preserving 3d CFTs, where ψi transforms as a vector under an O(N ) global symmetry. We compute bounds…

PUPT-2480 Bootstrapping 3 D Fermions

We study the conformal bootstrap for a 4-point function of fermions 〈ψψψψ〉 in 3D. We first introduce an embedding formalism for 3D spinors and compute the conformal blocks appearing in fermion…
