abstract
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.

A covariant framework identifies redefinition-invariant ALP couplings to gluons and quarks and computes physical decay rates for mixed scenarios.
Cell-level Transformers classify collimated ALP photon-jets versus single photons with AUC 0.98 and regress diphoton mass to ~64 MeV, beating shower-shape and other ML baselines in an ATLAS-like GEANT4 simulation.
Limits on axion-like particles from photon-coupling searches are recast as constraints on massive graviton-like particles across lab, astrophysical, and cosmological experiments using analogous Primakoff and Gertsenshtein conversion mechanisms.
Develops a statistical framework to constrain multiple kinetically mixed dark photons using standard experimental probes and distributions for mixing parameters.
Using S2 star periastron precession, the work constrains ultralight scalar dark matter mass ratios to below 10^{-3} or 1 and improves quadratic coupling bounds for masses 10^{-20} to 10^{-18} eV.
Tera-Z factories can produce millions of heavy neutral leptons and billions of axion-like particles under optimistic assumptions, turning them into exotics factories for discovery and detailed study.
NRQCD-based study projects BESIII and STCF sensitivity to light dark photons (m_U < 3 GeV) via visible and invisible J/ψ decay channels.
Thermal corrections to reheating and freeze-in DM production rates are generally small in the computable regime but can be large in constructed counter-examples.
Solar axion fluxes from 57Fe and 83Kr nuclear transitions differ by three orders of magnitude, yielding stronger constraints on |g_aN^eff × g_aγγ| and g_aγγ vs. m_a from Chandrayaan-2 XSM data for iron.
Photon inverse emission contributes to forward-backward asymmetry in LHC dilepton production, quantified via numerical analysis and additive relative corrections in high-mass kinematic regions.
