SIRENA -- Sum-Integral REductioN Algorithm
Luis Gil, Javier López Miras, Adrián Moreno-Sánchez
We present SIRENA, a Python and C++ implementation of the Laporta algorithm for the automatic reduction of multi-loop sum-integrals via integration-by-parts identities. The method…

Hard thermal contributions to phase transition observables at NNLO
Fabio Bernardo, Mikael Chala, Luis Gil +1
To construct the high-temperature effective field theory of gauge-Higgs models up to in the gauge coupling, we integrate out hard modes to three-loop level and u…

Thermoskyrmions
Mikael Chala, Juan Carlos Criado, Luis Gil
Skyrmions are stable and topologically non-trivial field configurations that behave like localized particles. They appear in the chiral effective theory for pions, where they corre…
