Our group hosts several different weekly activities. We have a series of regular seminars on Wednesdays at 15:00 in Room S named High Energy Theory Seminars (orange in the calendar), replaced by Theory Colloquia (yellow) once per month.
We also have informal discussions on Tuesdays in Room R, alternating between the Pheno-Coffee (pink) and the Theory-lunch (green).

If you have iCal, you can have our seminars added automatically to your calendars by subscribing (⌥⌘S) to the address http://active.pd.infn.it/g4/jccal.php.

Contraints on Neutrino Masses and the Cosmological Constant from Quantum Gravity Conjectures
Abstract
Consistency with quantum gravity can have significant consequences on low energy physics. For instance, using the Weak Gravity Conjecture, it has been recently argued by Ooguri and Vafa that non supersymmetric stable AdS vacua are incompatible with quantum gravity. However, it is known that AdS vacua can appear from compactifying the Standard Model to 2 or 3 dimensions. By requiring the absence of these vacua we can put constraints on the SM and BSM spectra, obtaining a lower bound for the cosmological constant in terms of the neutrino masses. This can also be translated into an upper bound for the EW scale around the TeV range, bringing a new perspective into the issue of the EW hierarchy.

The R* method and applications at five loops
Abstract
The R*-operation is a generalisation of BPHZ renormalisation to the subtraction of euclidean infrared divergences. It can be used to efficiently compute anomalous dimensions of arbitrary QFT correlators at L loops from single scale propagator integrals of L-1 loops. I will explain the method and present several results which were obtained with it, such as the 5-loop beta function in QCD for an arbitrary simple compact gauge group, the hadronic R-ratio and hadronic Higgs decay rates at N4LO, which were obtained using the same technique.
