Title: Effective Theory in a Time Dependent World
Host: John Terning
Room: 432
Abstract: We use the in-in or Schwinger-Keldysh formalism to explore the construction and interpretation of effective field theories for time-dependent systems evolving out of equilibrium. Starting with a simple model consisting of a heavy and a light scalar field taken to be in their free vacuum states at a finite initial time, we study the effects from the heavy field on the dynamics of the light field by analyzing the equation of motion for the expectation value of the light background field. New terms appear which cannot arise from a local action of an effective field theory in terms of the light field, though they disappear in the adiabatic limit. We discuss the origins of these terms as well as their possible implications for time dependent situations such as inflation.

Title: Goldstone meets Higgs at the LHC
Host: Yuhsin Tsai
Room: 432
Abstract: After the recent discovery at the LHC of a Higgs-like particle with mass around 125 GeV, it is mandatory to reassess the viability of the proposed solutions to the hierarchy problem of the electroweak scale. In this talk we will focus on compositeness as the fundamental idea, with the Higgs arising as a Goldstone-boson of the new strong dynamics. We will present this old proposal with all its modern developments, and discuss its exciting phenomenological implications, including the prospect of non-minimal scalar sectors and its significance for Higgs couplings.

Title:Neutrino & Dark Matter Coherent Interactions: New Avenues for Precision Measurements
Host:Svoboda
Room: 185
Abstract: In the search for physics beyond the Standard Model, big physics can still be done with small detectors. One such endeavor, the Coherent Germaniun Neutrino Technology (CoGeNT) experiment, began as an attempt to observe the long predicted coherent neutrino-nucleus scattering cross-section to produce sensitive tests for sterile neutrinos, radiative corrections above the weak scale and non-standard neutrino interactions. Interestingly, the coherent cross-section for WIMP Dark Matter scattering is analogous to that for neutrinos, making the CoGeNT detectors ideal for light WIMP detection. I will present the status of the research program, including the recent provocative hint of an annual modulation, a characteristic signature of Galactic Dark Matter. I will then pivot to a next generation effort to develop an information-rich suite of detectors which has its roots in the early developmental years of CoGeNT: a detector technology (MAGNeT) that utilizes dozens of target nuclei to study the coherent cross-sections of neutrino and Dark Matter interactions in detail. The aim is to move beyond the limitations and imprecision of contemporary experiments and theoretical calculations to finally realize the promise of coherent scattering for illuminating new physics. Along the way, I will share some fun experiments performed with these unique detectors, including searches for neutrino magnetic moments, axion-like dark pseudoscalars, and tests of neutrinos as minimum ionizing particles.
