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). Due to recent internet security problems at Cinvestav it will NOT be broadcasted via the DPyC facebook account (facebook is currently blocked on our premises).

The PICO collaboration leverages bubble chamber technology to search for these interactions, operating its detectors 2 km underground at SNOLAB to suppress cosmogenic backgrounds. Bubble chamber detectors offer two key advantages: insensitivity to gamma-induced recoils and flexibility in the choice of active fluid (PICO has previously operated with both C₃F₈ and CF₃I). While most direct detection experiments rely on heavier target nuclei, PICO's use of fluorinated organic compounds provides superior sensitivity to spin-dependent dark matter couplings; the low-mass nuclei also enable previous-generation detectors to set world-leading limits in exothermic channels such as fermionic absorption. PICO-40L is currently operating with C₃F₈, taking advantage of fluorine's strong proton coupling. Unlike its predecessor PICO-60, PICO-40L employs a right-side-up geometry designed to minimize particulate-induced backgrounds, a significant departure from previous generations. The detector serves as a proof-of-concept platform for the next-generation PICO-500, a 260 L detector projected to deliver world-leading sensitivity in this channel. This talk will present the current status of PICO-40L, provide an overview of the underlying bubble chamber technology, and outline projected sensitivities for PICO-500.
