title = "Proton Compton Scattering from Linearly Polarized Gamma Rays",
abstract = "Differential cross sections for Compton scattering from the proton have been measured at scattering angles of 55°, 90°, and 125° in the laboratory frame using quasimonoenergetic linearly (circularly) polarized photon beams with a weighted mean energy value of 83.4 MeV (81.3 MeV). These measurements were performed at the High Intensity Gamma-Ray Source facility at the Triangle Universities Nuclear Laboratory. The results are compared to previous measurements and are interpreted in the chiral effective field theory framework to extract the electromagnetic dipole polarizabilities of the proton, which gives αE1p=13.8±1.2stat±0.1BSR±0.3theo,βM1p=0.21.2stat±0.1BSR0.3theo in units of 10-4 fm3.",
