"We Hear You: What We Have Learned from the First Year of Data from the Campus Attitudes Toward Safety (CATS) Study"

Dr. Renzetti is Chair and Professor of Sociology at the University of Kentucky, and currently serves as the Judi Conway Patton Endowed Chair in the Center for Research on Violence Against Women.  She is also the editor of Violence Against Women: An International and Interdisciplinary Journal, the Oxford University Press Series on Interpersonal Violence, and the University of California Press Series on Gender and Justice.

Dr. Follingstad is the Women’s Circle Endowed Chair in the Center for Research on Violence Against Women and a Professor of Clinical and Forensic Psychology in the Department of Psychiatry, College of Medicine at the University of Kentucky (with a joint appointment in the Department of Psychology).  She is currently the Executive Director of the Center for Research on Violence Against Women at the University of Kentucky.

Dr. Renzetti and Dr. Follingstad will present findings from the latest Campus Attitudes Toward Safety (CATS) study and discuss what can be learned from the study and the importance of improving safety on campus for all students.

A reception will follow in the Alumni Gallery adjacent to the auditorium.

Theory Seminar: Searching for Physics Beyond the Standard Model from Lattice QCD

After the discovery of the Higgs boson, physicists keep searching for New Physics in cosmic, energy and intensity frontiers. In the intensity frontier, a key stone is to provide precise Standard Model prediction by controlling the uncertainty from low energy QCD.

Lattice QCD has been developed to tackle the nonperturbative problems in low energy QCD. It has been demonstrated to be a powerful tool in dealing with the ''gold-plated'' observables such as the hadron spectra and decay constants. To meet the requirement of future experiments in the intensity frontier, we need to study more complicated system beyond gold-plated.

Rare kaon decay is such an example. The cleanliness of the Standard Model predication of the branching ratio for the rare kaon decays K^+ -> pi^+ nu nu-bar and K_L -> pi^0 nu nu-bar make them an ideal place to search for New Physics. The CERN NA62 experiment aims for an observation of O(100) events of K^+ -> pi^+ nu nu-bar decay and a 10%-precision measurement of the branching ratio. The KOTO experiment at J-PARC in Japan aims for first observation of the CP-violating decay K_L -> pi^0 nu nu-bar.

In this talk I will present an exploratory study of the long-distance contributions to the K+ -> pi+ nu nu-bar decay amplitude from first principles using lattice QCD. Such study is necessary to interpret future experiments at a 10% precision or better.

Theory Seminar: Excited states from Lattice QCD

Monte Carlo calculations in Lattice QCD can be used to study the spectrum of quantum chromodynamics in a finite box from first principles. Most experimentally observable hadrons however appear as unstable resonances in scattering amplitudes and are hence not directly accessible through Euclidean time simulations in a finite volume. Fortunately the stationary-state energies in finite volume can be related to scattering phase shifts, hence allowing us to extract infinite-volume physics from Lattice QCD computations. These so-called Lüscher methods open exciting prospects for the study of resonant processes from first principles. In this talk I will review the stochastic LapH method for lattice spectroscopy, which enables us to systematically carry out this program. I will present results on pion-pion scattering from simulations at a single lattice spacing with $m_\pi = 240$ MeV. In the isovector channel, the large $L = 3.8$ fm volume enables good resolution of the $\rho$ resonance shape. Preliminary results from a different ensemble are also shown, including a first-principles determination of the low-energy contribution to the hadronic vacuum polarization.

Astro Seminar: Tidal Disruption Events from the Pan-STARRS1 Survey

If a star passes too close to the supermassive black hole in the center of its galaxy, it can be destroyed by tidal gravity and will subsequently accrete onto the black hole to produce an electromagnetic display. I will give an overview of the Medium Deep Survey of Pan-STARRS1, which was a recently concluded five-band survey of ten 7 sq. deg. fields to a nightly depth of 23.5 mag. We discovered more than 5000 optical transients in the 4+ years of the survey, which has allowed us to search for rare or novel events, including tidal disruption event (TDE) candidates. These events have the basic observational signatures expected of TDEs, but the theoretical interpretation of the emission remains challenging. In particular, the optical photospheres are substantially larger and cooler than expected for emission from an accretion disk formed at the tidal radius, which has led us to invoke reprocessing by unknown material at larger radius. If the optical emission and light curves can be interpreted correctly, TDEs have the promise of teaching us about the demographics of otherwise quiescent black holes in distant galaxies and about black hole accretion under different conditions than in steadily accreting quasars.

Algebra and Geometry Seminar

Title: Regularity of Fat Points
 
Abstract: Every point P in K^n, has an associated ideal I, which consists of the polynomials which vanish on it. Given P, we can define the fat point with weight m, as the ideal I^m. This ideal corresponds to polynomials which vanish on it, and whose m-1 partial derivatives vanish on it as well. The Hilbert function of intersections of these ideals is an interesting topic of study, as it has nice geometric meaning. I will discuss some results and conjectures about Hilbert functions of these ideals and their intersections, as well as discussing some work in progress in the area.
