Perturbed symmetric-product orbifold: first-order mixing and puzzles for integrability
Matheus Fabri, Alessandro Sfondrini, Torben Skrzypek
We study the marginal deformation of the symmetric-product orbifold theory Sym which corresponds to introducing a small amount of Ramond-Ramond flux into the dual $AdS_3\t…

One-loop integrability with shifting masses
Matheus Fabri, Davide Polvara
We investigate the perturbative integrability of two-dimensional massive quantum field theories with polynomial-like interactions and show that any theory of such class which is pu…

One-loop elastic amplitudes from tree-level elasticity in 2d
Matheus Fabri, Davide Polvara
In this paper we extend the study initiated in arXiv:2302.04709v2 [hep-th] to the computation of one-loop elastic amplitudes. We consider 1+1 dimensional massive bosonic Lagrangian…
