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…
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…
Running Couplings in High-Temperature Effective Field Theory
Mikael Chala, Andrii Dashko, Guilherme Guedes
In this work, we study the renormalization-group evolution of parameters in the three-dimensional effective field theory (3D EFT) that describes the thermally driven electroweak ph…
Potential Blind Directions at TeraZ
Mikael Chala, Juan Carlos Criado, Michael Spannowsky
The next generation of high-luminosity electron-positron colliders, such as FCC-ee and CEPC operating at the pole (TeraZ), is expected to deliver unprecedented precision in ele…
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…
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 resem…
