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.", "occurrence_notes":null, "guid":"150585-21909678@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/150585", "building_id":"1000167", "building_name":"West Hall", "campus_maps_id":"163", "room":"340", "location_name":"West Hall", "has_livestream":0, "cost":"", "tags":["Physics","Science"], "website":"", "sponsors":[ { "group_name":"HEP - Astro Seminars", "group_id":"3799", "website":"" }, { "group_name":"Department of Physics", "group_id":"1965", "website":"" } ], "image_url":"", "styled_images":{ "event_thumb":"", "event_large":"", "event_large_2x":"", "event_large_lightbox":"", "group_thumb":"", "group_thumb_square":"", "group_large":"", "group_large_lightbox":"", "event_large_crop":"", "event_list":"", "event_list_2x":"", "event_grid":"", "event_grid_2x":"", "event_feature_large":"", "event_feature_thumb":"" }, "occurrence_count":1, "first_occurrence":21909678 } , "153026-21914935": { "datetime_modified":"20260928T210311", "datetime_start":"20261005T150000", "datetime_end":"20261005T160000", "has_end_time":1, "date_start":"2026-10-05", "date_end":"2026-10-05", "time_start":"15:00:00", "time_end":"16:00:00", "time_zone":"America\/Detroit", "event_title":"Math Grad Show and Tell Seminar: The Limits of Axioms", "occurrence_title":"", "combined_title":"Math Grad Show and Tell Seminar: The Limits of Axioms: Zander Hill", "event_subtitle":"Zander Hill", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Has this ever happened to you?
