Direct Gamma and HBT

Direct Gamma and HBT. The key point is that ? 0 gammas will not produce an HBT peak that is detectable. Typical distance between two ? 0 s is 25 million Fermis! So the peak in relative momenta of the two gammas is 4 ? eV wide. HBT gives space-time information on the collision region.

Direct Gammas and HBT

Direct Gammas and HBT. Direct photons from the collision are an important, and different, signal carrying information about the collision system. The EM interaction is weak enough so that photons do not appreciably interact after emission.
