| Title | Observation of Correlations between Spin and Transverse Momenta in Back-to-Back Dihadron Production at CLAS12 | ||||
| Abstract | We report the first measurements of deep inelastic scattering spin-dependent azimuthal asymmetries in back-to-back hadron electroproduction, where two hadrons are produced in opposite hemispheres along the z-axis in the center-of-mass frame, with the first hadron produced in the current-fragmentation region and the other in the target-fragmentation region. The data were taken with longitudinally polarized electron beams of energy 10.2 and 10.6 GeV incident on an unpolarized liquid-hydrogen target using the CLAS12 spectrometer at Jefferson Lab. Observed non-zero sin ?? modulations in ep ? e?p?+ X events, where ?? is the difference of the azimuthal angles of the proton and pion in the virtual photon and target nucleon center-of-mass frame, indicate that correlations between the spin and transverse momenta of hadrons produced in the target- and current-fragmentation regions may be significant. The measured beam-spin asymmetries provide a first access in dihadron production to a previou | ||||
