Beam-Recoil Polarization Measurement

Sažetak
The helicity-dependent recoil proton polarizations P0 x and P0 z as well as the helicity-independent component Py have been measured in the pðe ; e ⃗ 0 p⃗Þπ0 reaction at four-momentum transfer Q2 ≃ 0.1 GeV2, center-of-mass proton emission angle θ p ≃ 90°, and invariant mass W ≃ 1440 MeV. This first precise measurement of double-polarization observables in the energy domain of the Roper resonance P11ð1440Þ by exploiting recoil polarimetry has allowed for the extraction of its scalar electroexcitation amplitude at an unprecedentedly low value of Q2, establishing a powerful instrument for probing the interplay of quark and meson degrees of freedom in the nucleon.
