No signal found in first search for eta to pi0 plus invisible dark scalar decay, setting branching fraction limits of (1.8-5.5)x10^-5 at 90% CL and improving DM-nucleon cross section bounds by ~5 orders of magnitude.
First muography at CJPL reconstructs directional overburden opacity map in agreement with satellite terrain models and predicts muon fluxes for CJPL-II halls.
Bayesian analysis finds that the likely ranges of light dark-matter fermion mass and exponential density-profile parameter in hyperon-containing neutron stars are nearly independent of the hadronic model for symmetry-energy slopes between 40 and 58 MeV, with HESS J1731-347 and GW170817 data playing,

Bayesian analysis of density profile of light dark matter elucidating the properties of dark matter admixed neutron stars in the presence of hyperons
