abstract
The problem of neutral-current processes (neutrino scattering, pair emission, pair absorption, axion emission, \etc) in a nuclear medium can be separated into an expression representing the phase space of the weakly interacting probe, and a set of dynamic structure functions of the medium. For a non-relativistic medium we reduce the description to two structure functions $S_A(\o)$ and $S_V(\o)$ of the energy transfer, representing the axial-vector and vector interactions. $S_V$ is well determined by the single-nucleon approximation while $S_A$ may be dominated by multiply interacting nucleons. Unless the shape of $S_A(\o)$ changes dramatically at high densities, scattering processes always dominate over pair processes for neutrino transport or the emission of right-handed states. Because the emission of right-handed neutrinos and axions is controlled by the same medium response functions, a consistent constraint on their properties from consideration of supernova cooling should use the same structure functions for both neutrino transport and exotic cooling mechanisms.

Disentangling axion-like particle couplings to nucleons via a delayed signal in Super-Kamiokande from a future supernova
A future nearby supernova could reveal sub-MeV axion-like particles through a delayed ~30 MeV photon signal in Super-Kamiokande and Hyper-Kamiokande, probing couplings down to about 3 x 10^-6.

Probing a diffuse flux of axion-like particles from galactic supernovae with neutrino water Cherenkov detectors
MeV-mass axion-like particles from galactic supernovae can form a diffuse flux detectable via a p -> p gamma in water Cherenkov detectors, and Super-Kamiokande data exclude a new region of the ALP parameter space.
