Abstract

The first process for the Latin American Strategy Forum for Research Infrastructure for High Energy, Cosmology and Astroparticle Physics (LASF4RI-HECAP) came to a conclusion in October 2020, with a Physics Briefing Book (PBB) presented in (2104.06852). Here we present an updated PBB, the result of the first update of LASF4RI-HECAP. The update process began with a call for White Papers from the HECAP community. The submitted contributions were presented at the III LASF4RI for HECAP Symposium: Update of the Strategic Plan, held at ICTP-SAIFR in São Paulo in August 26-29, 2024, with the participation of the Preparatory Group, High Level Strategy Group, Funding Agencies and representatives of similar efforts from around the globe. This updated PBB was written by the Preparatory Group based mainly on 46 White Papers submitted by the community and is organized around seven working groups: Astronomy, Astrophysics and Astroparticle Physics; Cosmology; Dark Matter; Neutrinos; Electroweak and Strong Interactions, Higgs Physics, CP and Flavour Physics and BSM; Instrumentation and Computing; Advanced Training and Capacity Building. It is intended to provide the essential input for the creation of a long-term HECAP strategy in the region.

  • Figure 1: Differential point source sensitivity for SWGO and SWGO-A compared to CTA South, HAWC, and LHAASO. While the continuous lines of SWGO show the expected sensitivity, as calculated from simulations, the light markers denote extrapolations. At altitudes above 4,400 meters, where joint environmental and infrastructure studies have been conducted, America plays a central role in SWGO’s development. The collaboration has over 130 scientists from more than 40 institutions, including strong participation from Argentina, Brazil, Bolivia, Chile, Colombia, Mexico, and Peru. These countries contribute across all fronts: from site characterization and detector R&D to simulation frameworks, prototype instrumentation, and science case development. The proposed sites are located in the Andes at altitudes above 4,400 meters, where joint environmental and infrastructure studies have been conducted to assess feasibility. Ulisses Barres, from Brazil, is one of the current vice-spokespersons
