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…
Matchotter: An Automated Tool for Dimensional Reduction at Finite Temperature
Javier Fuentes-MartÃn, Javier López Miras, Adrián Moreno-Sánchez
At finite temperature, the decoupling of heavy Matsubara modes allows a four-dimensional quantum field theory to be matched onto a purely spatial, three-dimensional effective field…
New insights into two-loop running in effective field theories
Mikael Chala, Javier López Miras
We show that, by viewing a 4D effective-field theory as the infrared (IR) limit of the compactified version in 5D, we can compute two-loop anomalous dimensions without gauge-breaki…
Efficient on-shell matching
Mikael Chala, Javier López Miras, José Santiago +1
We propose an efficient method to perform on-shell matching calculations in effective field theories. The standard off-shell approach to matching requires the use of a Green's basi…
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…
