Yun-Tse Tsai (SLAC/Stanford) "Exploring ν Territory: Using LArTPC Technology ("ν“ here is a Greek alphabet accounting for neutrinos)"
February 28, 2017 @ 4:00 pm - 5:00 pm
The discovery of neutrino oscillation, which implies neutrinos have non-zero masses, is the first instance of a conflict with the Standard Model of particle physics. The fruitful results from neutrino experiments in the past two decades have opened a window into a new territory, where the unanswered questions in the current theory, such as the observed matter-antimatter asymmetry, may be addressed by the upcoming precision measurements.
In this talk, I will introduce the core topics of neutrino physics and the requirements of neutrino experiments, focusing on the technology of liquid argon time projection chamber (LArTPC). The outstanding spatial and energy resolution of LArTPC provides us with a promising apparatus for the required precision. In particular, I will discuss detection of neutrinos from supernova explosions, and searches for other weakly interacting particles as well as rare physics processes. I will talk about the MicroBooNE experiment, the first large LArTPC in the U.S., its recent results, and the future LArTPC experiments.
