dc.description.abstractA precision measurement of the differential cross sections π‘‘β’πœŽ/𝑑⁒𝛺 and the linearly polarized photon asymmetry 𝛴 ≑(π‘‘β’πœŽβŠ₯ βˆ’π‘‘β’πœŽβˆ₯)/(π‘‘β’πœŽβŠ₯ +π‘‘β’πœŽβˆ₯) for the →𝛾⁒𝑝 β†’πœ‹0⁒𝑝 reaction in the near-threshold region has been performed with a tagged photon beam and almost 4β’πœ‹ detector at the Mainz Microtron. The Glasgow-Mainz photon tagging facility along with the Crystal Ball/TAPS multiphoton detector system and a cryogenic liquid hydrogen target were used. These data allowed for a precise determination of the energy dependence of the real parts of the 𝑆- and all three 𝑃-wave amplitudes for the first time and provide the most stringent test to date of the predictions of chiral perturbation theory and its energy region of agreement with experiment.en
