Evidence of a dibaryon spectrum in coherent $I ¨ ^{0} I ¨ ^{0} d$ photoproduction at forward deuteron angles

T. C. Jude, S. Alef, R. Beck +27

The coherent reaction, $I^^{3} d \to I ¨ ^{0} I ¨ ^{0} d$ was studied with the BGOOD experiment at ELSA from threshold to a centre-of-mass energy of 2850\,MeV. A full kinematic reconstru…

First measurement using elliptically polarized photons of the double-polarization observable $E$ for $I^^{3} p \to p I ¨ ^{0}$ and $I^^{3} p \to n I ¨ ^{+}$

A2 Collaboration, F. Afzal, K. Spieker +74

We report the measurement of the helicity asymmetry $E$ for the $p I ¨ ^{0}$ and $n I ¨ ^{+}$ final states using, for the first time, an elliptically polarized photon beam in combination wit…

Evaluation of the E2/M1 ratio in the $N \to I^ (1232)$ transition from the $I^^{3} p \to p I ¨ ^{0}$ reaction

E. Mornacchi, P. Pedroni, F. Afzal +59

A new data set for the helicity-dependent differential cross section of the single-meson photoproduction reaction $I^^{3} p \to p I ¨ ^{0}$ was obtained for the photon energy interval 150…
