Ll. Frankfurt et al., COLOR TRANSPARENCY EFFECTS IN ELECTRON DEUTERON INTERACTIONS AT INTERMEDIATE Q(2), ZEITSCHRIFT FUR PHYSIK A-HADRONS AND NUCLEI, 352(1), 1995, pp. 97-113
High momentum transfer electrodisintegration of polarized and unpolari
zed deuterium targets, d(e, e'p)n is studied. We show that the importa
nce of final state interactions FSI, occuring when a knocked out nucle
on interacts with the other nucleon, depends strongly on the momentum
($) over right arrow p(n) of the spectator nucleon. In particular, the
se FSI occur when the essential contributions to the scattering amplit
ude arise from internucleon distances similar to 1.5 fm. But the absor
ption of the high momentum gamma may produce a point like configurati
on, which evolves with time. In this case, the final state interaction
s probe the point like configuration at the early stage of its evoluti
on. If the point like configuration is still small after propagating a
bout 1.5 fm, the FSI are suppressed. The result is that significant co
lor transparency effects, which can either enhance or suppress compute
d cross sections, are predicted to occur for Q(2) greater than or simi
lar to 4 GeV2. We suggest searching for color transparency phenomenon
by examining ratios of experimentally measured quantities. Possible th
eoretical uncertainties of the calculations, including those due to th
e deuteron wave function and relativistic effects, are found to be sma
ll.
