Measurements of the generalized electric and magnetic polarizabilities of the proton at low Q2 using the virtual Compton scattering reaction
Experimental details of a virtual Compton scattering (VCS) experiment performed on the proton at the MIT-Bates out-of-plane scattering facility are presented. The VCS response functions P[scubscript LL]−P[scubscript TT]/P[scubscript TT]ɛɛ and P[scubscript LT] have been measured at Q[superscript 2]=0...

| description | Experimental details of a virtual Compton scattering (VCS) experiment performed on the proton at the MIT-Bates out-of-plane scattering facility are presented. The VCS response functions P[scubscript LL]−P[scubscript TT]/P[scubscript TT]ɛɛ and P[scubscript LT] have been measured at Q[superscript 2]=0.057 GeV[superscript 2]/c[superscript 2]. The generalized electric and magnetic polarizabilities, α(Q[superscript 2]) and β(Q[superscript 2]), and the mean-square electric polarizability radius(r[subscript α][superscript 2]) are obtained from a dispersion analysis of the data. The results are in good agreement with O(p[superscript 3]) heavy baryon chiral perturbation and indicate the dominance of mesonic effects in the polarizabilities. |
