“…The Snowmass contribution [948] studied the prospects for testing minimal extensions of the SM featuring a single new light mediator coupled through one of the portal interactions at present and future high intensity experiments. This includes electron and proton beam fixed target and beam dump experiments, medium energy e + e − colliders / meson factories, and auxiliary LHC detectors.…”

With the establishment and maturation of the experimental programs searching for new physics with sizeable couplings at the LHC, there is an increasing interest in the broader particle and astrophysics community for exploring the physics of light and feebly-interacting particles as a paradigm complementary to a New Physics sector at the TeV scale and beyond. FIPs 2020 has been the first workshop fully dedicated to the physics of feebly-interacting particles and was held virtually from 31 August to 4 September 2020. The workshop has gathered together experts from collider, beam dump, fixed target experiments, as well as from astrophysics, axions/ALPs searches, current/future neutrino experiments, and dark matter direct detection communities to discuss progress in experimental searches and underlying theory models for FIPs physics, and to enhance the cross-fertilisation across different fields. FIPs 2020 has been complemented by the topical workshop “Physics Beyond Colliders meets theory”, held at CERN from 7 June to 9 June 2020. This document presents the summary of the talks presented at the workshops and the outcome of the subsequent discussions held immediately after. It aims to provide a clear picture of this blooming field and proposes a few recommendations for the next round of experimental results.

“…There are several new-physics scenarios one can test at near-detector complexes. Many have received a lot of attention in the last few years and have been explored by the theory and phenomenology community WP [34,35,36]. These have also drawn the attention of the experimental community.…”

“…For νA → N X A + γ scattering, on the other hand, where N is a heavier sterile neutrino, the final state photon would be softer and could potentially match the MiniBoone measurements (for sample of other new physics explanations of the MiniBoone anomaly, see, e.g., Refs. [57][58][59][60][61][62][63]). We leave the full investigation of such a possibility for future work.…”

We point out that neutrinos can have enhanced couplings to photons, if light (pseudo)scalar mediators are present, resulting in potentially measurable neutrino polarizability. We show that the expected suppression from small neutrino masses can be compensated by the light mediator mass, generating dimension 7 Rayleigh operators at low scales. We explore the rich phenomenology of such models, computing in details the constraints on the viable parameter space, spanned by the couplings of the mediator to neutrinos and photons. Finally, we build several explicit models that lead to enhanced neutrino polarizability by modifying the inverse see-saw majoron, i.e., the pseudo-Nambu-Goldstone boson of the U (1) L global lepton number responsible for generating small neutrino masses.
