Using the recently introduced boundary form factor bootstrap equations, the form factors of boundary exponential operators in the sinh-Gordon model are constructed. The ultraviolet scaling dimension and the normalization of these operators are checked against previously known results. The construction presented in this paper can be applied to determine form factors of relevant primary boundary operators in general integrable boundary quantum field theories.

    hep-th 2026-07 conditional novelty 6.0 of 10

    In the Federbush model, branch-point twist field form factors and first-order quench corrections are independent of the topological coupling λ, so Rényi entropies of the infinite-volume vacuum match two free Dirac fermions.

    hep-th 2025-01 reject novelty 6.0 of 10

    The paper constructs deformed boundary minimal form factors for T anti-T perturbed theories and rewrites the sinh-Gordon Dirichlet minimal form factor in the same block form, but the central solution formula has a sign error.
