From tree- to loop-simplicity in affine Toda theories II: higher-order poles and cut decompositions (2023)
Journal Article
Dorey, P., & Polvara, D. (2023). From tree- to loop-simplicity in affine Toda theories II: higher-order poles and cut decompositions. Journal of High Energy Physics, 2023(10), Article 177. https://doi.org/10.1007/jhep10%282023%29177

Recently we showed how, in two-dimensional scalar theories, one-loop threshold diagrams can be cut into the product of one or more tree-level diagrams [1]. Using this method on the ADE series of Toda models, we computed the double- and single-pole co...

One-loop inelastic amplitudes from tree-level elasticity in 2d (2023)
Journal Article
Polvara, D. (2023). One-loop inelastic amplitudes from tree-level elasticity in 2d. Journal of High Energy Physics, 2023(4), Article 20. https://doi.org/10.1007/jhep04%282023%29020

We investigate the perturbative integrability of different quantum field theories in 1+1 dimensions at one loop. Starting from massive bosonic Lagrangians with polynomial-like potentials and absence of inelastic processes at the tree level, we derive...

Tree level integrability in 2d quantum field theories and affine Toda models (2022)
Journal Article
Dorey, P., & Polvara, D. (2022). Tree level integrability in 2d quantum field theories and affine Toda models. Journal of High Energy Physics, 2022(2), https://doi.org/10.1007/jhep02%282022%29199

We investigate the perturbative integrability of massive (1+1)-dimensional bosonic quantum field theories, focusing on the conditions for them to have a purely elastic S-matrix, with no particle production and diagonal scattering, at tree level. For... Read More about Tree level integrability in 2d quantum field theories and affine Toda models.

Quantum anomalies in Ar(1) Toda theories with defects (2019)
Journal Article
Penati, S., & Polvara, D. (2019). Quantum anomalies in Ar(1) Toda theories with defects. Journal of High Energy Physics, 2019(6), Article 62. https://doi.org/10.1007/jhep06%282019%29062

We study quantum integrability of ane Toda theories with a line of defect. In particular, we focus on the problem of constructing quantum higher-spin conserved currents in models dened by two A(1) r Toda theories separated by a non-trivial type-I def...
