摘要
Neutrino mass and mixing are amongst the major discoveries of recent years and demand that we revise the long-standing Standard Model of Particle Physics. Experiments have provided unambiguous evidence for the oscillation of neutrinos but many important questions remain: Are neutrinos their own antiparticles? What is their mass scale? Is there CP violation in the lepton sector? I will describe precision studies of antineutrino oscillation with the KamLAND and Daya Bay reactor experiments and discuss the prospects for understanding the nature of neutrino mass with CUORE, the Cryogenic Underground Observatory for Rare Events.
报告人简介
Professor Karsten Heeger received his undergraduate degree in physics from Oxford University and his Ph.D. from the University of Washington in Seattle where he worked with Prof. Hamish Robertson on a model-independent measurement of the solar 8B neutrino flux in the Sudbury Neutrino Observatory (SNO). For his thesis work he was awarded the 2003 APS Dissertation Award in Nuclear Physics. Before joining the faculty at the University of Wisconsin he was a Chamberlain Fellow and scientist in the Physics Division at Lawrence Berkeley National Laboratory. He currently works on precision studies of neutrino oscillation with reactor antineutrinos in the Daya Bay and KamLAND reactor neutrino experiments and the search for neutrinoless double beta decay with the CUORE experiment. In 2008 he received Outstanding Junior Investigator awards from DOE High Energy Physics for the search for the last unknown neutrino mixing angle theta13 at Daya Bay and from DOE Nuclear Physics for the investigation of neutrino properties with bolometric detectors. Karsten was awarded an Alfread P. Sloan Research Fellowship in 2009.
