Abstract (english)
Virtual Compton scattering on the proton has been investigated at three yet unexplored values of the four-momentum transfer Q2: 0.10, 0.20, and 0.45 GeV2, at the Mainz Microtron. Fits performed using either the low-energy theorem or dispersion relations allowed the extraction of the structure functions PLL − PTT=ϵ and PLT, as well as the electric and magnetic generalized polarizabilities αE1 ðQ2Þ and βM1 ðQ2Þ. These new results show a smooth and rapid falloff of αE1 ðQ2Þ, in contrast to previous measurements at Q2 ¼ 0.33 GeV2, and provide for the first time a precise mapping of βM1 ðQ2Þ in the low-Q2 region.
