SUMMARY:Looking for hot physics in ultracold places - Kevin Peter Hickerso
 n (UCLA)
DTSTART:20141209T150000Z

CONTACT:Nick Barlow
DESCRIPTION:The LHC has helped complete the Standard Model\; it has also l
 eft open some gaping holes. Among these are any prediction of dark matter\
 , a sufficient source for the matter and antimatter imbalance in the unive
 rse or an\nadequate explanation of neutrino mass. In this talk\, I will de
 scribe experimental techniques that use beta decay at ultra low temperatur
 es\, to search parameter space not yet easily accessible to accelerators. 
 Half\nof the talk will be devoted to ultracold neutrons (UCN)\, that allow
  us to probe TeV scale physics by trapping these 1 mK  free neutrons. One 
 such experiment\, UCN$\\tau$\, aims to measure the neutron lifetime\, curr
 ently unresolved by a discrepancy large enough to hint at new physics. The
  other half of the talk will be about CUORE\, an experiment that uses near
 ly 1 ton\nof ultracold bolometers at 10 mK to look for neutrinoless double
  beta decay\, a process that can detect strong lepton number violation.
