Description
AMBER is a new QCD facility at CERN's SPS M2 secondary beam line, which aims to study fundamental properties of hadrons. The first approved experimental phase includes measuring the antiproton production cross-section, which is essential for indirect dark matter searches using cosmic-ray antiprotons. It also includes measuring the proton's charge radius using high-energy muons and investigating hadron structure and the emergence of hadron mass using Drell–Yan reactions and charmonium production.
In this talk, I will outline the physics motivations and methodologies behind the various AMBER measurements and their anticipated scientific impact. I will present the first results from the antiproton-production measurements conducted in 2023 and 2024, as well as the current status of preparations for future measurements, particularly the proton radius measurement. I will also briefly discuss plans for a second phase of AMBER, which will focus on measurements with a high-intensity kaon beam after 2030.
