Color Glass Condensate and the Glasma

New forms of matter have been proposed to explain features of high energy scattering. The Color Glass Condensate is high energy density and highly coherent matter. This matter controls the initial state of high energy collisions. When two sheets of Colored Glass collide at high energy, the sheets become dusted with color electric and color magnetic charge, resulting in longitudinal color electric and magnetic fields connecting the two sheets. Such fields are called a Glasma, since the Glasma arises from Colored Glass and evolves towards a Quark Gluon Plasma. Various observations at HERA at DESY, the Relativistic Heavy Ion Collider at Brookhaven National Lab, and the Large Hadron Collider are naturally explained by the CGC and the Glasma.
