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

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

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