Abstract |
|
|
| The effect of the omega- meson (w-meson) on the unpolarized semi-exclusive structure functions for the incoherent neutral
pion electroproduction form the deuteron at different values for the squared four-momentum transfer (K2) and the virtual photon lab
energy (klab
0 ). is studied. The study is carried out in the impulse approximation (IA) i.e. the final state interactions are neglected. The
elementary amplitude for pion electroproduction is taken from the MAID-2007 model. The contribution of w-meson to the structure
functions is noticeable which decrease, it increasing (klab
0 ). While increasing (K2) lead to a small increase in the effect of w-meson
contribution to the structure functions. |
