Revealing Deaths of Massive Stars with GeV-TeV Neutrinos


CCAPP Mini-Workshop on
"Revealing Deaths of Massive Stars with GeV-TeV Neutrinos"

Thursday August 2nd through Friday August 3rd, 2012
Location: M2015 Physics Research Building
Organized by: Basudeb Dasgupta, Shunsaku Horiuchi, Kohta Murase (chair), and Carsten Rott

The Center for Cosmology and AstroParticle Physics (CCAPP) at The Ohio State University (OSU) is holding a workshop on "Revealing Deaths of Massive Stars with GeV-TeV Neutrinos" in Columbus, Ohio on August 2-3, 2012.

The Aim of the Workshop:
MeV thermal neutrinos are relevant as a probe of supernovae, and detections play an important role in revealing the explosion mechanism and thermal physics of the central engine. MeV neutrinos were indeed detected by Kamiokande. TeV nonthermal neutrinos have been theoretically discussed mainly in view of the connection to cosmic rays, especially UHECRs. IceCube is a suitable detector, but they have not yet detected these neutrinos and the nonthermal mechanisms are highly uncertain. MeV neutrinos are mainly produced in the compact region of 10^6 cm, whereas >TeV neutrinos are produced beyond the photosphere, i.e., >10^12 cm. It seems natural to expect GeV neutrinos in the intermediate range. Detecting MeV-GeV-TeV neutrinos will allow us to reveal the progenitor star, circumstellar environment, and connection between GRBs and SNe.
