Chiba University Particle Physics Group
We had the UHE Neutrino Telescope Workshop 2003 on July 29th - 30th in Chiba Univ. 2003/06/09 Renewed this web page. Details of IceCube and UHE Neutrino Astronomy can be found here. Although there should be a theoretical upper bound of extragalactic cosmic ray energies, existence of cosmic rays beyond this limit was indicated by AGASA. We develop the medical imaging system called PET (Positron Emission Tomography) with making use of e e- pair annihilation at National Institute of Radiological Sciences.
