The joint observation of core-collapse supernovae with gamma-ray bursts shows
that jets can be launched in the aftermath of stellar core collapse, likely by
a newly formed black hole that accretes matter from the star. Such gamma-ray
bursts have only been observed accompanying Type Ibc supernovae, indicating a
stellar progenitor that lost its Hydrogen envelope before collapse. It is
possible that jets are launched in core-collapse events even in the presence of
a Hydrogen envelope, however, such jets are unlikely to be able to burrow
through the star and will be stalled before escaping. High-energy neutrinos
produced by such choked jets could escape the stellar envelope and could be
observed. Here we examine how multi-messenger searches for high-energy
neutrinos and core-collapse supernovae can detect or limit the fraction of
stellar collapses that produce jets. We find that a high fraction of jet
production is already limited by previous observational campaigns. We explore
possibilities with future observations using LSST, IceCube and Km3NET.
