论文摘要
我们在1982年的CERN质子束转储实验中重新审视了与大型欧洲泡沫室的重型中性瘦室的搜索，重点是比Kaon重，并且仅与Tau Neutrinino混合，因为这些质量的约束要比其对应物与较小的质量或其他混合物的约束要差得多。根据该模型重塑以前的搜索并包括额外的生产和衰减通道，迄今为止，最强的界限到tau质量。这也适用于我们对重中性瘦素与电子中微子混合的更新边界。
We revisit the search for heavy neutral leptons with the Big European Bubble Chamber 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. Recasting the previous search in terms of this model and including additional production and decay channels yields the strongest bounds to date, up to the tau mass. This applies also to our updated bounds on the mixing of heavy neutral leptons with the electron neutrino.
