Charm jet identification in searches for new physics with the ATLAS detector
Time: 12:00 pm - 1:00 pm
Place: 4274 Chamberlin
Speaker: Dan Guest, Yale University
Abstract: The first hints of new physics at the LHC may come in the form of extremely short-lived particles which decay instantly to particles in the standard model. These decays could appear as an excess of events in any number of channels. Until recently, searches for such an excess have often neglected decays through charm quarks, owing to the lack of an efficient charm jet identification algorithm.

I will introduce several supersymmetric models where decays through charm quarks are preferred. These searches motivated the development of a lifetime-based charm jet identification algorithm. After discussing this algorithm, I will present the results from two scalar quark searches, where charm jet identification played a central role in extending the previous experimental limits

The status of India-based Neutrino Observatory (INO)
Time: 2:30 pm - 3:30 pm
Place: 5310 Chamberlin Hall
Speaker: Bannanje Sripathi Acharya, Tata Institute
Abstract: In this talk I shall narrate our plans of building a new underground laboratory facility in southern India called India-based neutrino observatory (INO). A 50 kilo-ton magnetised Iron CALorimeter (ICAL)is one of the first experiments proposed to be housed in this observatory for the study of neutrino properties like mass hierarchy, precision measurement of oscillation parameters etc. using the atmospheric neutrinos. The details of this ICAL project and its present status will also be covered in this talk.
