PROCEDURE FOR DIRECT MEASUREMENT OF THE CABIBBO-KOBAYASHI-MASKAWA ANGLE-GAMMA

A natural procedure is presented to measure the angle gamma from the d ecay B+/- --> pi(+/-)pi(+)pi(-). It is based in the Dalitz plot fittin g analysis. Neither amplitudes nor strong phases have to be known a pr iori. We present simulations of this decay computing both statistical and theoretical uncertainties and analyze the experimental feasibility . We found that gamma could be measured with a combined error of the o rder of 20 degrees with 90% of C.L. after about a couple of years of r unning of the first generation of B factories.
