Effect of omega(782) resonance on the response functions for d(e,e’π+)nn reaction
Journal Title: Eurasian journal of physics and functional materials - Year 2018, Vol 2, Issue 2
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 (Q2) and the virtual photon lab energy (k0lab). 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.
