Description
We revisit the search for heavy neutral leptons using BEBC in the 1982 proton beam dump experiment at CERN, focussing on those heavier than the kaon and mixing only with the tau neutrino, as these are far less constrained than their counterparts with smaller mass or other mixings. Carrying out a full reanalysis of the previous data in terms of this model and including additional production and decay channels yields the strongest laboratory bounds to date up to the tau mass.
