Flavour Symmetries / Neutrinos
- Claudia Cornella
We propose a model in which the proton is rendered absolutely stable by an IR mechanism that remains robust against unknown quantum gravity effects. An anomaly-free linear combination of baryon number and lepton flavors is gauged and spontaneously broken to a residual $Z_9$ discrete gauge symmetry, enforcing a strict selection rule in the SMEFT: baryon number violation occurs only in multiples...
Baryon and lepton number are excellent low-energy symmetries of the Standard Model (SM) that tightly constrain the form of its extensions. In this paper we investigate the possibility that these accidental symmetries are violated in the deep UV, in such a way that one multiplet necessary for their violation lives at an intermediate energy scale M above the electroweak scale. We write down the...
We study the sensitivity of COHERENT-like experiments to non-standard contributions within the so-called $\nu$WEFT framework. The latter is the most general low-energy effective field theory that includes not only the light SM fields but also additional right-handed Dirac neutrinos.
Our analysis uses the framework presented at "Consistent QFT description of non-standard neutrino...
Given the known non-negligible interplay between large-x PDFs and new physics signals, what PDFs are suitable for new physics searches?
In this talk I discuss the fine balance between the benefit of constraining PDFs with high-energy observables to reduce their uncertainties in the large-x region that is relevant for new physics searches and the risk of fitting away potential signs of new...
