Two-Loop Infrared Renormalization with On-shell Methods
Pietro Baratella, Sara Maggio, Michael Stadlbauer +1
Within the framework proposed by Caron-Huot and Wilhelm, we give a recipe for computing infrared anomalous dimensions purely on-shell, efficiently up to two loops in any massless t…
RG of GR from On-shell Amplitudes
Pietro Baratella, Dominik Haslehner, Maximilian Ruhdorfer +2
We study the renormalization group of generic effective field theories that include gravity. We follow the on-shell amplitude approach, which provides a simple and efficient method…
Anomalous Dimensions of Effective Theories from Partial Waves
Pietro Baratella, Clara Fernandez, Benedict von Harling +1
On-shell amplitude methods have proven to be extremely efficient for calculating anomalous dimensions. We further elaborate on these methods to show that, by the use of an angular…
Renormalization of Higher-Dimensional Operators from On-shell Amplitudes
Pietro Baratella, Clara Fernandez, Alex Pomarol
On-shell amplitude methods allow to derive one-loop renormalization effects from just tree-level amplitudes, with no need of loop calculations. We derive a simple formula to obtain…
The Supercooled Universe
Pietro Baratella, Alex Pomarol, Fabrizio Rompineve
Strongly-coupled theories at the TeV can naturally drive a long period of supercooling in the early universe. Trapped into the deconfined phase, the universe could inflate and cool…
A closer look to the sgoldstino interpretation of the diphoton excess
P. Baratella, J. Elias-Miro, J. Penedo +1
We revisit the sgoldstino interpretation of the diphoton excess in the context of gauge mediation. While the bound on the gluino mass might seem to make the sgoldstino contribution…
