D. Kharzeev et A. Leonidov, MEASURING THE HADRONIZATION LENGTH IN E- -]K(0)(K)OVER-BAR(0)GAMMA(E), Physics letters. Section B, 329(2-3), 1994, pp. 374-378
We propose to study the space-time picture of hadronization by looking
at the angular distribution of photons emitted in the process e+e- --
> K0K0gammaBAR at DAPHINE energies. It is shown that the angular distr
ibutions are quite sensitive to the hadronization length.
