Physics Division Seminars bring us speakers on a variety of physics related subjects. Usually these are held in the Building 6008 large Conference Room, at 3:00 pm on the chosen day, but times and locations may vary. For more information, contact our seminar chairman,

We'll discuss two initiatives in astroparticle and neutrino physics at the University of Chicago, both sharing in common the revival and revision of old technologies to address new experimental challenges.
COUPP employs ultra-stable heavy liquid bubble chambers to search for WIMP dark matter. First results leading to improved limits on spin-dependent WIMP couplings will be presented, together with the most recent progress and plans. COGENT aims at the detection of very faint (~100 eV) signals in detectors massive enough to allow searches for rare processes, using recently developed p-type point contact (ppc) Germanium detectors. The broad range of applications (coherent neutrino scattering, light WIMP searches, double-beta decay) available for these new semiconductor devices will be described, as well as the status of an ongoing reactor (anti)neutrino experiment.
