Kin: the optimal variable for CP-violation
S. Henrot-Versillé, F. Le Diberder
Abstract
We advocate the use of an optimal variable to demontrate CP violation. 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).
