论文摘要
核心偏离超新星的中心是宇宙中最密集的环境之一。在这样的条件下，可以想象，从普通核物质到夸克 - 胶质等离子体发生了一阶相变。这种过渡会释放出大量的潜热，可以驱动超新星爆炸，并可能在中微子信号中印断尖锐的签名。我们展示了该快照特征，如果在大规模中微子探测器上观察到该快速特征如何在中微子质量上设定竞争极限，并通过三角剖分来帮助超新星的定位。 95 \％c.l。中微子质量的限制可以达到冰立方体中的0.16〜EV，在Hyper-Kamiokande中的0.22〜EV和沙丘中的0.58〜EV达到10 kpc的超新星。对于相同的距离和最乐观的中微子转换案例，三角剖分方法可以在$ \ sim 0.3^{\ circ} -9.0^{\ circ} $中限制超新星本地化的角度不确定性，并在探测器对的两对中，导致了人们的兴趣升高，从而经常出现了一定的文献。
The centers of the core-collapse supernovae are one of the densest environments in the Universe. Under such conditions, it is conceivable that a first-order phase transition from ordinary nuclear matter to the quark-gluon plasma occurs. This transition releases a large amount of latent heat that can drive a supernova explosion and may imprint a sharp signature in the neutrino signal. We show how this snap feature, if observed at large-scale neutrino detectors, can set competitive limits on the neutrino masses and assist the localization of the supernova via triangulation. The 95\%C.L. limit on the neutrino mass can reach 0.16~eV in Ice-Cube, 0.22~eV in Hyper-Kamiokande, and 0.58~eV in DUNE, for a supernova at a distance of 10 kpc. For the same distance and in the most optimistic neutrino conversion case, the triangulation method can constrain the $1σ$ angular uncertainty of the supernova localization within $\sim 0.3^{\circ}-9.0^{\circ}$ in the considered pairs of the detectors, leading to an improvement up to an order of magnitude with respect to the often considered in the literature rise time of the neutronization burst.
