2561 DPyC SMF false [["minutes", "Minutes"], ["notes", "Notes"], ["paper", "Paper"], ["poster", "Poster"], ["slides", "Slides"], ["summary", "Summary"]] Cinvestav ea481e58ca9c64e14d7982cb66bcd604 3312 The Division of Particles and Fields of the Mexican Physical Society (DPyC-SMF) organizes every year the Annual Meeting (RADPyC). This space is dedicated mainly for the exposure of results of graduate students and young researchers working in high energy physics and includes some review talks on the hot topics of the field. This year the meeting will be held in Auditorio José Ádem, Cinvestav, Mexico City, México. The scientific programme will consist of invited and contributed talks, and a poster session. It will begin in the morning of Wednesday 17 June and end before lunch on Friday 19 June. We will have the following invited talks: - Ana Colmenero, HAWC (UMSNH) - Jens Erler, The EW SM and constraints on NP (Mainz, PRISMA) - Iván Martínez Soler, Neutrino physics (Durham Univ.) - Cristina Oropeza, CMS (Ibero) - Antonio Ortiz, ALICE (ICN-UNAM) - Gabriel Palacios, Accelerator physics (UNAM) - Antonio Pich, Flavor physics (IFIC) - Pedro Podesta, Belle-II (UAS) - Selomit Ramírez, QCD, Loop Tree Duality, Quantum Computing (UAS) - Saúl Ramos, Flavor physics from a top-down perspective (IF-UNAM) - Alfredo Raya, NICA (UMSNH) - Eric Vázquez, DM-neutrinos (exp.) (IF-UNAM) The whole event can be followed by Zoom: https://us02web.zoom.us/j/85815121456?pwd=t1JWdqhgarEQRyewmXIEzNlkIcqU8a.1 (858 1512 1456 & 044752).

These de-excitation products contribute to the visible energy and timing structure of events in liquid argon neutrino detectors. This is especially relevant for the Coherent CAPTAIN Mills (CCM) experiment, a 10 ton liquid argon detector at LANL that relies on fast timing and prompt-light observables to study electron neutrino interactions in the $E_\nu \leq 50$ MeV regime. The MARLEY event generator predicts final states for neutrino interactions with argon using measured gamma-ray decay schemes and statistical nuclear emission models. In most cases, nuclear de-excitation levels have picosecond or femtosecond lifetimes, and the emitted gamma rays are effectively prompt on CCM timescales. However, metastable states can produce delayed gamma emission on a nanosecond timescale, providing a characteristic signature that may be observable with CCM's fast timing capabilities. In this work, we present a time resolved extension of MARLEY focused on gamma emission from metastable de-excitation levels. We apply this extension to simulated electron-neutrino events and study metastable level populations. These observables connect nuclear structure information to detector-level timing quantities and provide a means to test the prompt gamma approximation for CC neutrino interactions.
