13 Mexican Workshop on Particles and Fields (MWPF), Leon, Mexico, 20 - 26 October 2011, vol.378
The main ingredients and the importance of the process D-+/- -> K--/+pi(+/-)pi(+/-) are described: its contribution to reveal the true nature of the scalar K*(0) particle, what we know about the parametrization of its dynamics, its importance for CPV in the charm physics and possible new physics contributions.
