									<p>Title: Supernova neutrinos – flavor evolution and signals
</p>
<p>Speaker: Tina Lund, North Carolina State University, USA
</p>
<p>Location: 1520-516<br><br>Time: 15.15-16.00
</p>
<p>Abstract:<br>Neutrinos are unique messengers of what transpires inside a core-collapse supernova. About 99% of the gravitational energy released during the collapse, escapes in neutrinos. Their copious amounts, and relatively unhindered travel to Earth provide us with a tremendous source of information on the explosion mechanism. The only way we can get at that information, and in the process learn about supernova neutrinos themselves, is if an observed supernova neutrino signal can be decoded. This requires detailed knowledge of the neutrino flavor evolution inside the exploding star. We need to know what is the combined effect of neutrino self-interactions and Mikheyev-Smirnov-Wolfenstein resonances, and what changes when the stellar matter is turbulent.<br> In this talk I will briefly outline some of the components needed to calculate the neutrino flavor evolution inside a core-collapse supernova. Then I will highlight a few of the things we might learn from a supernova neutrino signal, both about neutrino oscillations and about the Standing Accretion Shock Instability as a viable explosion mechanism.</p>
