Multipole sensitivity to phase variation in pion photo-and electroproduction analyses

L. Markou, E. Stiliaris, C. N. Papanicolas

We use the Athens Model Independent Analysis Scheme (AMIAS) to examine the validity of using the Fermi-Watson theorem in the multipole analyses of pion photoproduction and electrop…

On hadron deformation: a model independent extraction of EMR from pion photoproduction data

L. Markou, E. Stiliaris, C. N. Papanicolas

The multipole content of pion photoproduction at the resonance has been extracted from a data set dominated by recent Mainz Microtron (MAMI) precision measurements. Th…

Measurement of the Partial Cross Sections s(TT), s(LT) and [s(T)+epsilon*s(L)] of the p(e,e' pi+)n Reaction in the Delta(1232) Resonance

J. M. Kirkpatrick, N. F. Sparveris

We report new precision p(e,e' pi+})n measurements in the Delta(1232) resonance at Q2 = 0.127(GeV/c)2 obtained at the MIT-Bates Out-Of-Plane scattering facility. These are the lowe…

Virtual Compton Scattering measurements in the transition

N. F. Sparveris, P. Achenbach, C. Ayerbe Gayoso +30

We report on new H measurements in the resonance at (GeV/c) carried out simultaneously with H. It is the lowest for w…

Multipole Extraction: A novel, model independent method

E. Stiliaris, C. N. Papanicolas

A novel method for extracting multipole amplitudes in the nucleon resonance region from electroproduction data is presented. The method is based on statistical concepts and it reli…

Determination of quadrupole strengths in the gamma*p-->Delta(1232) transition at Q2= 0.20 (GeV/c)2

N. F. Sparveris, P. Achenbach, C. Ayerbe Gayoso +29

We report new precise p measurements at the peak of the resonance at $Q^2=\unit[0.20](GeV/c)^2$ performed at the Mainz Microtron (MAMI). The…
