Survey of neutrino flavor predictions and the neutrinoless double beta decay funnel
/ Denton, Peter B. (Brookhaven) ; Gehrlein, Julia (Colorado State U., Fort Collins ; CERN ; Brookhaven)
The neutrinoless double beta decay experimental effort continues to make tremendous progress with hopes of covering the inverted neutrino mass hierarchy in coming years and pushing from the quasi-degenerate hierarchy into the normal hierarchy. As neutrino oscillation data is starting to suggest that the mass ordering may be normal, we may well be faced with staring down the funnel of death: a region of parameter space in the normal ordering where -- for a particular cancellation among the absolute neutrino mass scale, the Majorana phases, and the oscillation parameters -- the neutrinoless double beta decay rate may be vanishingly small.

Neutrino Constraints and the ATOMKI X17 Anomaly
/ Denton, Peter B. (Brookhaven Natl. Lab.) ; Gehrlein, Julia (CERN)
Recent data from the ATOMKI group continues to confirm their claim of the existence of a new $\sim17$ MeV particle. We review and numerically analyze the data and then put into context constraints from other experiments, notably neutrino scattering experiments such as the latest reactor anti-neutrino coherent elastic neutrino nucleus scattering data and unitarity constraints from solar neutrino observations. [...]

Solar Parameters in Long-Baseline Accelerator Neutrino Oscillations
/ Denton, Peter B. (Brookhaven) ; Gehrlein, Julia (Brookhaven ; CERN)
Long-baseline (LBL) accelerator neutrino oscillation experiments, such as NOvA and T2K in the current generation, and DUNE-LBL and HK-LBL in the coming years, will measure the remaining unknown oscillation parameters with excellent precision. These analyses assume external input on the so-called ``solar parameters,''$\theta_{12}$ and $\Delta m^2_{21}$, from solar experiments such as SNO, SK, and Borexino, as well as reactor experiments like KamLAND.

(Harvard U.) et al.
Astrophysical neutrinos are excellent probes of astroparticle physics and high-energy physics. With energies far beyond solar, supernovae, atmospheric, and accelerator neutrinos, high-energy and ultra-high-energy neutrinos probe fundamental physics from the TeV scale to the EeV scale and beyond.

(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.

Neutrino Self-Interactions: A White Paper
/ Berryman, Jeffrey M. (Washington U., Seattle ; UC, Berkeley) ; Blinov, Nikita (Victoria U.) ; Brdar, Vedran (Fermilab ; Northwestern U.) ; Brinckmann, Thejs (INFN, Ferrara ; Ferrara U.) ; Bustamante, Mauricio (Bohr Inst.) ; Cyr-Racine, Francis-Yan (New Mexico U.) ; Das, Anirban (SLAC) ; de Gouvêa, André (Northwestern U.) ; Denton, Peter B. (Brookhaven Natl. Lab.) ; Dev, P.S. Bhupal (Washington U., St. Louis) et al.
Neutrinos are the Standard Model (SM) particles which we understand the least, often due to how weakly they interact with the other SM particles. Beyond this, very little is known about interactions among the neutrinos, i.e., their self-interactions. [...]
