Compton scattering from the proton

First extraction of the scalar proton dynamical polarizabilities from real Compton scattering data

“…We used two different data sets, i.e., all the available experimental data for the unpolarized cross sections below pion-production threshold, denoted as FULL data set 1 (for a total of 150 data points) [26,[31][32][33][34][36][37][38][39][40][41][42], and the data set given by the TAPS experiment alone (55 data points) [26], which is, by far, the most comprehensive available subset. "Improved" data sets have been defined in recent fits of RCS observables, by discarding some data points from different experiments [4,20,43].…”

Effective theory of theΔ(1232)resonance in Compton scattering off the nucleon

“…During the past decade a number of excellent experimental programs have been dedicated to these two processes (see Refs. [1][2][3][4][5] and [6][7][8][9][10], respectively). At low photon energies, these experiments probe the static properties of the nucleon, such as its electric charge, magnetic moment, and polarizabilities.…”

“…It was also studied above the (1232) at Bonn [32], Saskatoon [33], and Tokyo [34,35]. The Cornell experiment [36] measured the RCS process at photon energies E γ in the range 2-6 GeV and angles from 45 • to 128 • in the center-of-mass frame.…”
