Theory Seminar (High Energy/Cosmology)
Very Light Stops at the LHC
Time: 2:15 pm
Place: 5280 Chamberlin Hall
Speaker: David Morrissey, TRIUMF
Abstract: Supersymmetry can stabilize the weak scale against quantum corrections, produce a viable dark matter candidate, and provide an explanation for the excess of matter over antimatter. If supersymmetry is realized in Nature, for every known particle there exists a superpartner particle differing in spin by half a unit. Stops, the spin-zero superpartners of the top quark, play a key role in determining the phenomenological signals of supersymmetry. In this talk I will discuss the many reasons why at least one of the stops might have a mass only slightly above the weak scale, and I will describe some of the ways that such a light stop can be searched for and discovered at the LHC.

Physics Department Colloquium
Gas-filled detectors: the Darwinian Champions of Particle Physics
Time: 3:30 pm
Place: 2241 Chamberlin Hall (coffee at 4:30 pm)
Speaker: David Nygren, Lawrence Berkeley National Laboratory
Abstract: The first detection of single ionizing events occurred more than 100 years ago when Ernest Rutherford and Hans Geiger succeeded in recording alpha particles from radon decay using a gas-filled detector and an electrometer. Remarkably diverse and useful innovations followed and continue to emerge even today, establishing gas-filled detectors as the exemplary evolutionary survivors in nuclear and particle physics technique. Although this ample record has many interesting chapters, I will focus on my favorite topics within this humble corner of the quest to understand our universe. The evolution of these devices is interesting not only for their substantial contribution to experiment, but also for what was, surprisingly, overlooked as technology evolved.
