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…
Hot news on the phase structure of the SMEFT
Mikael Chala, Maria Cristina Fiore, Luis Gil
We perform dimensional reduction of the electroweak sector of the dimension-six SMEFT to order in coupling constants . This analysis includes one-loop contributions to kin…
Phase Transitions in Dimensional Reduction up to Three Loops
Mikael Chala, Luis Gil, Zhe Ren
We perform the first computation of phase-transition parameters to cubic order in , where is the scalar mass and is the temperature, in a simple model resemb…
Higher-order corrections to phase-transition parameters in dimensional reduction
Mikael Chala, Juan Carlos Criado, Luis Gil +1
The dynamics of phase transitions (PT) in quantum field theories at finite temperature is most accurately described within the framework of dimensional reduction. In this framework…
