This variable, named the Kin variable, provides a means to visualize graphically CP violation, to pin point the most statistically powerful events, and to combine several channels and experiments. For the B0->J/PSiKs channel, its use leads to a straightforward measurement of sin(2beta).4pages, pdf fileHigh Energy Physics - ExperimentKin: the optimal variable for CP-violationtext
