Description
Neutrinos from Supernova 1987A were detected in coincidence in 3 different detectors (Baksan, IMB and Kamioka). However, only the Mont Blanc detector registered an early burst 4.7 hours before the other 3 detectors. This paper examines possible explanations for the non-observation of the early burst in the 3 detectors, and the possible astrophysical scenarios for a double burst, such as a QCD phase transition to quark matter. Future multi-flavour capability by combining hydrogenous detectors with detector primarily sensitive to νe like the proposed HALO-1kT could help resolve this issue for future galactic core-collapse supernovae.
