Probing invisible particles with charm
0 Abstract: We point out opportunities to probe invisible particles, left- and right-handed neutrinos, axion-like particles (ALPs) and dark photons (Z′)(Z′) with rare decays of charm hadrons. We employ [...] employ and recast existing searches in D→(π,ω)X, D0→X and Λc→pX, where X denotes one of the above invisible final states including dineutrinos. The branching ratios are clean null tests of the standard model …
