“…The olivegreen regions show other terrestrial constraints, including the CASPEr ZULF experiments [16,61] , K-3 He comagnetometer bounds [10,22,62], and Long range constraints on ALPproton [63] and ALP-neutron [22] couplings. In beige, the astrophysical limits from not observing solar ALPs in the Solar Neutrino Observatory (SNO) [64] and neutron stars cooling considerations (NS) from ALP-neutron interactions [65] and estimates of ALP-proton interactions [66][67][68] are shown. The region above the dashed gray line is excluded by supernova (SN) cooling considerations and neutrino flux measurements [8,49,50].…”

We report on the first results of the Noble and Alkali Spin Detectors for Ultralight Coherent darK matter (NASDUCK) collaboration. We search for the interactions of Axion-Like Particles (ALPs) with atomic spins using an earth-based precision quantum detector as it traverses through the galactic dark matter halo. The detector is composed of spin-polarized xenon gas which can coherently interact with a background ALP dark matter field and an in-situ rubidium Floquet optical-magnetometer. Conducting a five months-long search, we derive new constraints on ALP-proton and ALP-neutron interactions in the 4 × 10 −15 − 4 × 10 −12 eV/c 2 mass range. Our limits on the ALP-proton (ALP-neutron) couplings improve upon previous terrestrial bounds by up to 3 orders of magnitude for masses above 4 × 10 −14 eV/c 2 (4 × 10 −13 eV/c 2 ). Moreover, barring the uncertain supernova constraints, the ALP-proton bound improves on all existing terrestrial and astrophysical limits, partially closing the unexplored region for couplings in the range 10 −6 GeV −1 to 2 × 10 −5 GeV −1 . Finally, we also cast bounds on pseudo-scalar dark matter models in which dark matter is quadratically-coupled to the nucleons.

“…It has promising applications in solar neutrino physics where the ν e can be detected at low energies [76]. Moreover, such a detector can also probe beyond standard model physics such as proton decay [77][78][79], neutrinoless double beta decay [80,81], and axions from the Sun [82].…”

For the next galactic supernova, operational neutrino telescopes will measure the neutrino flux several hours before their optical counterparts. Existing detectors, relying mostly on charged current interactions, are mostly sensitive to νe and to a lesser extent to ν e . In order to measure the flux of other flavors (ν µ , νµ , ν τ , and ντ ), we need to observe their neutral current interactions with the detector. Such a measurement is not only crucial for overall normalization of the supernova neutrino flux but also for understanding the intricate neutrino oscillation physics. A deuterium based detector will be sensitive to all neutrino flavors. In this paper, we propose a 1 kton deuterated liquid scintillator (DLS) based detector that will see about 435 neutral current events and 170 (108) charged current ν e (ν e ) events from a fiducial supernova at a distance of 10 kpc from Earth. We explore the possibility of extracting spectral information from the neutral current channel (−) ν d → (−) ν np by measuring the quenched kinetic energy of the proton in the final state, where the neutron in the final state is tagged and used to reduce backgrounds.

“…The axion flux from the (5.5 MeV) reaction, which provides one of the most intense axion fluxes from nuclear reactions, has been experimentally searched for by Borexino [ 63 ]. More recently, the SNO data [ 64 ] has also been scrutinized for traces of these 5.5 MeV axions. Helioscopes can, in principle, also be equipped with a -ray detector to look for such axions.…”

Probing the axion–nucleon coupling with the next generation of axion helioscopes

A finite axion–nucleon coupling, nearly unavoidable for QCD axions, leads to the production of axions via the thermal excitation and subsequent de-excitation of $$^{57}$$ 57 Fe isotopes in the sun. We revise the solar bound on this flux adopting the up to date emission rate, and investigate the sensitivity of the proposed International Axion Observatory IAXO and its intermediate stage BabyIAXO to detect these axions. We compare different realistic experimental options and discuss the model dependence of the signal. Already BabyIAXO has sensitivity far beyond previous solar axion searches via the nucleon coupling and IAXO can improve on this by more than an order of magnitude.
