Peer reviewed articles and other publications by this group are listed here , and conference contributions among the conference contributions of the Physics Department. The neutrino group studies the actual topics related to underground experiments. The Sun produces energy by nuclear reactions that also produce neutrinos. The observed neutrino flux is, however, only a fraction of the predicted flux. Also the observations of neutrinos produced by cosmic rays hitting the atmosphere of the earth deviate from the predictions.
Neutrinos play an important role for the dynamics of supernovae .
During the collapse of a star a huge amount of neutrinos is produced, so that most of the released gravitational energy is released as neutrinos. The outgoing neutrinos blow up the outer regions of the star, and they also affect the nuclear composition of the matter in such a way that may allow the synthesis of the heaviest elements. The effects of neutrino transformations on the above phenomena in supernovae has been extensively studied within the High Energy Physics Division. As a relic of the Big Bang the Universe is full of neutrinos. The relic neutrinos are dark matter , and if neutrinos are massive enough, they may form part or all of the missing matter.
