Terminology
Abstract
Charged-current (anti)neutrino interactions create and hyperons inside the nucleus, making hyperon final-state interactions a terrestrial probe of the in-medium potentials that govern hyperon onset in neutron stars. In the StrangeMC simulation the trapped- fraction, escaping hyperon momenta, and a kaon-vetoed+ tag respond monotonically to U and U at SBND and DUNE. Marginalised over the low-density slope, a forecast gives delta U about6 with systematics distinct from hypernuclear data; U is limited by hyperon--nucleon cross sections.
