Dynamical study of the 2H(e,e′π+) reaction
The 2H(e,e′π+) reaction in parallel kinematics has been investigated using a dynamical model of pion electroproduction on the nucleon. A unitary πNN model has been used in order to examine the effects due to the final two-nucleon interactions, pion rescattering from the second nucleon, and intermedi...

Dynamical study of the 2H(e,e′π+) reaction |
| abstract |
The 2H(e,e′π+) reaction in parallel kinematics has been investigated using a dynamical model of pion electroproduction on the nucleon. A unitary πNN model has been used in order to examine the effects due to the final two-nucleon interactions, pion rescattering from the second nucleon, and intermediate NN and NΔ interactions. It has been found that these πNN mechanisms are small, but they can have significant contributions to the 2H(e,e′π+) cross sections through their interference with the dominant impulse term. For the longitudinal cross sections, the effects due to the interference between the pion pole term and other production mechanisms are also found to be very large. Our findings clearly indicate that these interference effects must be accounted for in any attempt to determine from the 2H(e,e′π+) data whether the pion form factor and/or πNN vertex of the pion pole term are modified in the nuclear medium. |

A unitary πNN model has been used in order to examine the effects due to the final two-nucleon interactions, pion rescattering from the second nucleon, and intermediate NN and NΔ interactions. It has been found that these πNN mechanisms are small, but they can have significant contributions to the 2H(e,e′π+) cross sections through their interference with the dominant impulse term. For the longitudinal cross sections, the effects due to the interference between the pion pole term and other production mechanisms are also found to be very large. Our findings clearly indicate that these interference effects must be accounted for in any attempt to determine from the 2H(e,e′π+) data whether the pion form factor and/or πNN vertex of the pion pole term are modified in the nuclear medium.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">APS Digital Backfile Archive 1893-2003</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Hafidi, K.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Lee, T.-S.
