Model-Independent Extraction of the N*(1535) Electrostrong Form Factor from Eta Electroproduction
M. Benmerrouche, Nimai C. Mukhopadhyay, J. -F. Zhang
We analyze the existing data on electroproduction of eta mesons in the region of W~1.5GeV, and extract an electrostrong form factor for the N*(1535) electroexcitation and decay int…
Photoproduction of Etas and N(1535) Electrostrong Properties
Nimai C. Mukhopadhyay, J. -F. Zhang, M. Benmerrouche
From the new Mainz data of eta photoproduction off protons\cite{ref1} and deuterons\cite{ref2}, we can extract, via the effective Lagrangian approach (ELA)\cite{ref3}, the electros…
Extraction of the Ratio of the N^*(1535) Electromagnetic Helicity Amplitudes from Eta Photoproduction off Neutrons and Protons
Nimai C. Mukhopadhyay, J. -F. Zhang, M. Benmerrouche
Using the recent precise measurements of eta photopro- duction in proton and deuteron targets, we extract the ratio of the helicity amplitudes A^n_1/2 / A^p_1/2, for the excitation…
Photoproduction of the Etas near Threshold
Nimai C. Mukhopadhyay, J. -F. Zhang, M. Benmerrouche
We extract a parameter , a characteristic product of the strong and electromagnetic amplitudes for the N^*(1535), to be (2.20+-0.15) in unit of 10^(-4)MeV^(-1) from the new data…
Photo- and electroproduction of the eta and eta-prime mesons
Nimai C. Mukhopadhyay, J. -F. Zhang, M. Benmerrouche
We discuss the eta and eta prime photo- and electroproduction as a way to probe the nucleon resonance structure.
Photoproduction of the Eta-Prime Mesons as a New Tool to Probe Baryon Resonances
J. -F. Zhang, Nimai C. Mukhopadhyay, M. Benmerrouche
We examine eta prime photoproduction, as a novel tool to study baryon resonances around 2 GeV, of particular interest to the quark shell model, which predicts a number of them. We…
