Effect of Omega(782) resonance on the response functions for d(e,e’π+)nn reaction

Abstract

In the present work we study the effect of the Omega ( ω(782) ) resonance on the response functions for the incoherent positive pion electroproduction on the deuteron at different values of the squaredfour-momentum transfers (Q 2) and the virtual photon lab energy ( klab0). 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 and slightly increases with increasing virtual photon lab energy. © 2018. All Rights Reserved.
