Laser Spectroscopy of the Ground-State Hyperfine Splitting in Muonic HydrogenHYBRID

Laser spectroscopy of muonic hydrogen (μp) is an ideal platform to probe the proton structure. At the Paul Scherrer Institute, the CREMA collaboration aims to measure the ground-state hyperfine splitting (1sHFS) with a relative accuracy of 10⁻⁶ to infer the proton structure contribution (two-photon exchange correction) with a relative accuracy of 10⁻⁴. For this measurement, we develop a pulsed laser system with the aim of delivering 3 mJ pulses at a wavelength of 6.8 µm stochastically triggered by the arrival of muons. In this talk, I will explain the measurement principle and the present state of our experiment.
