A perturbative Liouville prescription for the celestial three-gluon amplitude
Grzegorz Biskowski, Franco Ferrari, Marcin R. Piatek +1
We study the celestial three-gluon amplitude in a dilaton background through the Mellin-Liouville formulation proposed by Stieberger, Taylor and Zhu (STZ). The original map contain…

Small- expansion of the DOZZ formula for light operators
Franco Ferrari, Marcin R. Piatek, Artur R. Pietrykowski
We present a systematic small- expansion of the Liouville DOZZ three-point structure constant in the light-operator regime \(α_i=bÏ_i\) as \(b\to0\). In this limit, the exact…

2D CFT and efficient Bethe ansatz for exactly solvable Richardson-Gaudin models
Grzegorz Biskowski, Franco Ferrari, Marcin R. Piatek
This work inaugurates a series of complementary studies on Richardson-Gaudin integrable models. We begin by reviewing the foundations of classical and quantum integrability, recall…
