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…

Dressing Factors for Mixed-Flux Superstrings
Sergey Frolov, Davide Polvara, Alessandro Sfondrini
We propose the dressing factors for the scattering of massive particles on the worldsheet of mixed-flux superstrings, in the string and mirror kinematic…
