Summary
A new explanation for the two detected neutrino bursts with an interval of about 4.5 hours is suggested. We propose that the first neutrino burst may have been caused by the collapse of a massive star and the second may have been due to the phase transition from neutron phase to quark cluster phase.
Riassunto
Si suggerisce una nuova spiegazione per le due esplosioni rivelate di neutrini con un intervallo di circa 4.5 ore. Si propone che la prima esplosione di neutrini possa essere stata causata dal collasso di una stella con massa e la seconda sia stata dovuta alla transizione di fase da quella dei neutroni a quella del cluster dei quark.
Резюме
Предлагается новое обьяснение двух зарегистрированных нейтринных вслышек с интервалом около 4,5 часов. Мы предлолагаем, что первая нейтринная вспышка обусловлена коллапсом массивной звезды, а вторая вызвана фазовым переходом из нейтронной фазы в фазу кваркового кластера.
