Quantum interferometry in rho{sup 0} production in ultra-peripheral heavy ion collisions

PDF Version Also Available for Download.

Description

In {rho}{sup 0} photoproduction in ultra-peripheral heavy ion collisions, either ion can be the photon emitter or the target. The two possibilities are indistinguishable, and they should be able to interfere, reducing {rho}{sup 0} production at low transverse momentum, p{sub T} < {h_bar}/<b>, where <b> is the median impact parameter. The two {rho}{sup 0} production points are separated by <b> {approx} 18-46 fm, while the {rho}{sup 0} decay before travelling 1 fm. The two decay points are well separated in spacetime, so the decays proceed independently and any interference must involve the final state {pi}{sup +}{pi}{sup -}. This requires a ... continued below
