(Fermilab) et al.
This white paper provides a comprehensive review of our present understanding of experimental neutrino anomalies that remain unresolved, charting the progress achieved over the last decade at the experimental and phenomenological level, and sets the stage for future programmatic prospects in addressing those anomalies. It is purposed to serve as a guiding and motivational "encyclopedic" reference, with emphasis on needs and options for future exploration that may lead to the ultimate resolution of the anomalies.

White Paper on New Opportunities at the Next-Generation Neutrino Experiments (Part 1: BSM Neutrino Physics and Dark Matter)
/ Argüelles, C.A. (MIT) ; Aurisano, A.J. (Cincinnati U.) ; Batell, B. (Pittsburgh U.) ; Berger, J. (Pittsburgh U.) ; Bishai, M. (Brookhaven Natl. Lab.) ; Boschi, T. (Queen Mary, U. of London) ; Byrnes, N. (Texas U., Arlington) ; Chatterjee, A. (Pittsburgh U. ; Texas U., Arlington) ; Chodos, A. (Texas U., Arlington) ; Coan, T. (Southern Methodist U.) et al.
With the advent of a new generation of neutrino experiments which leverage high-intensity neutrino beams for precision measurements, it is timely to explore physics topics beyond the standard neutrino-related physics. Given that the realm of beyond the standard model (BSM) physics has been mostly sought at high-energy regimes at colliders, such as the LHC at CERN, the exploration of BSM physics in neutrino experiments will enable complementary measurements at the energy regimes that balance that of the LHC.

Al (Oxford U.) et al.
The nature of dark matter and properties of neutrinos are among the most pressing issues in contemporary particle physics. The dual-phase xenon time-projection chamber is the leading technology to cover the available parameter space for Weakly Interacting Massive Particles (WIMPs), while featuring extensive sensitivity to many alternative dark matter candidates.

The Present and Future Status of Heavy Neutral Leptons

The existence of non-zero neutrino masses points to the likely existence of multiple SM neutral fermions. When such states are heavy enough that they cannot be produced in oscillations, they are referred to as Heavy Neutral Leptons (HNLs). [...]

Search for rare decays of $D^0$ mesons into two muons
/ LHCb Collaboration
A search for the very rare $D^0 \to \mu^+\mu^-$ decay is performed using data collected by the LHCb experiment in proton-proton collisions at $\sqrt{s} = 7$, 8 and $13~\rm{TeV}$, corresponding to an integrated luminosity of $9~\rm{fb^{-1}}$. The search is optimised for $D^0$ mesons from $D^{\ast+}\to D^0\pi^+$ decays but is also sensitive to $D^0$ mesons from other sources. [...]

Amplitude analysis of $B^0 \rightarrow \overline{D}^0 D_s^+ \pi^-$ and $B^+ \rightarrow D^- D_s^+ \pi^+$ decays
/ LHCb Collaboration
Resonant contributions in $B^0 \rightarrow \overline{D}{}^0 D^+_s\pi^-$ and $B^+\rightarrow D^- D^+_s\pi^+$ decays are determined with an amplitude analysis, which is performed both separately and simultaneously, where in the latter case isospin symmetry between the decays is assumed. The analysis is based on data collected by the LHCb detector in proton-proton collisions at center-of-mass energies of 7, 8 and 13 TeV. [...]

Test of lepton universality in $b \rightarrow s \ell^+ \ell^-$ decays
/ LHCb Collaboration
The first simultaneous test of muon-electron universality using $B^{+}\rightarrow K^+\ell^+ \ell^−$ and $B^{0} \rightarrow K^{*0} \ell^{+} \ell^{−}$ decays is performed, in two ranges of the dilepton invariant-mass squared, $q^{2}$. The analysis uses beauty mesons produced in proton-proton collisions collected with the LHCb detector between 2011 and 2018, corresponding to an integrated luminosity of 9 $\mathrm{fb}^{-1}$. [...]
