Abstract

In present work we study the effect of the Omega (ω (782)) resonance on the response functions for the incoherent positive pion electroproduction forms the deuteron at different values for the four-momentum transfers squared (Q2) and the virtual photon lab energy (𝑘𝑘0𝑙𝑙𝑙𝑙𝑙𝑙). 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 effect seems to be very small but almost increase with increasing the virtual photon lab energy.
