National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Quantum Interferometry in p(sup O) Production in Ultra-Peripheral Heavy Ion Collisions.

DE2004829998

Publication Date	2004
Personal Author	Klein, S. R.
Page Count	12
Abstract	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 underline 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 non-local wave function.
