SUMMARY:Workshop / Seminar:CA Seminar: Bernstein-Sato polynomials and log resolutions by orbifolds
DESCRIPTION:Abstract: The Bernstein-Sato polynomial is an important invariant of singularities\, intimately related to the monodromy of the Milnor fiber\, the log canonical threshold\, and rational and Du Bois singularities. A classical method introduced by Kashiwara and refined by Lichtin provides estimates for the roots of the Bernstein-Sato polynomial in terms of a log resolution. In this talk\, we extend their method to log resolutions by orbifolds\, which has applications to the singularities of weighted homogeneous and Khovanskii non-degenerate complete intersections.

SUMMARY:Workshop / Seminar:HEP-Astro Seminar | Low-Energy Physics in Liquid Argon Time Projection Chamber Neutrino Detectors
DESCRIPTION:Liquid argon time projection chamber (LArTPC) detectors have become the global technology of choice for performing neutrino flavor oscillation measurements with accelerator neutrino beams.  The millimeter-precision 3D images these detectors produce contain meters-long tracks and showers generated by neutrino interaction products\, as well as mm-scale blips generated by isolated MeV-scale energy depositions.  While GeV track and shower features have been extensively leveraged for oscillation and neutrino-nucleus cross-section measurements\, MeV-scale blip features are comparatively under-studied\, despite their ability to uniquely access a range of physics and astrophysics signatures.  In this talk\, I will overview the physics benefits of MeV-scale reconstruction in neutrino LArTPCs\, including solar and supernova neutrino burst detection\, improved particle identification and hadronic calorimetry for beam neutrino measurements\, and more.  I will also present work performed by the LArTPC-focused Littlejohn Neutrino research Group experiment at IIT that has created new low-energy LArTPC reconstruction tools\, demonstrated new MeV-scale LArTPC physics capabilities\, and performed new particle physics measurements relying on these new techniques.
