Method for determining the D0-D0 mixing parameters.

We propose a new method to determine the mass and width differences of the two D meson mass eigenstates as well as the CP violating parameters associated with D0-D[over ]0 mixing. We show that an accurate measurement of all the mixing parameters is possible for an arbitrary CP violating phase, by combining observables from a time dependent study of D decays to a doubly Cabibbo suppressed mode with information from a CP eigenstate. As an example we consider D0-->K*0pi0 decays where the K*0 is reconstructed in both K+pi- and K(S)pi0.

Weak phase gamma using isospin analysis and time-dependent asymmetry in B(d)-->K(S)pi(+)pi(-).

We present a method for measuring the weak phase gamma using isospin analysis of three body B decays into Kpipi channels. Differential decay widths and time-dependent asymmetry in B(d)-->K(S)pi(+)pi(-) mode needs to be measured into even isospin pipi states. The method can be used to extract gamma, as well as the size of the electroweak penguin contributions.
