Particle resonances of the proton. The computer display shows the scattering of electrons by protons,which produces a series of resonances of the proton,in the CLAS experiment at Jefferson Lab,Virginia. The proton & its resonances are visible in the graph as black & coloured peaks or hills. The vertical axis is equivalent to scatter- ing angle,the horizontal axis shows energy in GeV. Colour represents the number of events,from black (most events) to blue. The sharp peak at left is the proton itself; the peak at 1.2 GeV is a resonance called the delta; towards the right many resonances are smeared together | |
