Events at Physics
Events on Tuesday, November 22nd, 2016
- Chaos & Complex Systems Seminar
- Asleep or awake? Local sleep in health and disease
- Time: 12:05 pm
- Place: 4274 Chamberlin (refreshments will be served)
- Speaker: Stephanie Jones, UW Department of Medicine and Public Health
- Abstract: The group of researchers at the Wisconsin Institute for Sleep and Consciousness at UW-Madison is arguably one of the best in the world, and some truly ground-breaking work on the function of sleep has been generated here. This talk will highlight much of this work and will focus, in particular, on the brain’s remarkable capacity for sleeping (and waking) at the same time, and the implications this has for brain health, development and disease.
- Host: Clint Sprott
- NPAC (Nuclear/Particle/Astro/Cosmo) Forum
- An overview of FBK Silicon Photomultipliers characterization
- Time: 2:30 pm
- Place: 5310 Chamberlin hall
- Speaker: Daniela Simone, INFN Bari
- Abstract: I will report a characterization of the NUV Silicon Photomultipliers (SiPMs) developed by Fondazione Bruno Kessler and tested at INFN in Bari (Italy). A dedicated setup has been built in order to measure crucial parameters such as gain, correlated noise and signal – to –noise ratio. The devices tested are SiPMs of different cell size and areas in single or matrix configuration. In particular, I will present last results concerning laboratory tests on the new NUV High Density SiPMs, which are characterised by an increased fill factor respect to the NUV devices.
- Host: Justin Vandenbroucke
- Theory Seminar (High Energy/Cosmology)
- Neutrino Masses: First Signal From SUSY!
- Time: 3:30 pm
- Place: 5280 Chamberlin
- Speaker: Seyda Ipek, Fermilab
- Abstract: We know neutrinos have mass, but we don't know how they get their masses. Many models augment the Standard Model with right-handed neutrinos, either Dirac or Majorana, to generate the neutrino masses. I will show that in R-symmetric supersymmetric models, the bino and its Dirac partner the singlino can play the role of right-handed neutrinos. In this mechanism the neutrino masses are generated in a very simple fashion. I will also discuss low and high energy constraints/signatures in this framework.
