  • Experimental Particle Physics Seminar: "Search for right-handed W and heavy neutrinos in the 2l+2j final state at CMS"

    David Rittenhouse Laboratory, 4C8

    Jorge Chaves, Cornell University

    Despite the discovery of the standard model (SM) Higgs boson, there are still unanswered questions that are not explained by the SM, such as the nature of the chiral structure of weak interactions. During Run-1 at the LHC, no clear signs for physics beyond the SM were seen, but there were a few hints of possible new physics. One particular hint was a 2.8\sigma excess seen at the CMS experiment in the search for a heavy right-handed W and heavy neutrino. These particles arise when a left-right symmetry is added to the electroweak sector.

  • Condensed Matter Seminar: "Physics of the Peacock’s Dance"

    David Rittenhouse Laboratory, A4

    Suzanne Amador Kane, Haverford College

    Peacocks are the textbook example of an elaborate mating display--and hence of sexual selection in evolution.  To seduce females, male peafowl perform a complicated dance in which they tilt, pivot and shake their elaborate, iridescent train feathers to present a dazzling visual display accompanied by mechanical sounds.  The eye-like ocelli that decorate these feathers are structurally-colored:  their vivid hues change with viewing angle because they arise from interference of light with photonic crystals of melanin nanorods.  Furthermore, like many birds, peacocks

  • Math-Bio seminar: "Does antibiotic resistance evolve in hospitals?"

    318 Carolyn Lynch Laboratory

    Bernd Sturmfels, University of California, Berkeley

    We present a joint paper with Anna Seigal, Portia Mira and Miriam Barlow, aimed at addressing the question in the title. Nosocomial outbreaks of bacteria and the heavy usage of antibiotics suggest that resistance evolves in hospital environments. To test this assumption, we studied resistance phenotypes of bacteria collected from patient isolates at a community hospital. A graphical model analysis shows no association between resistance and patient information other than time of arrival. This allows us to focus on time course data.
