The scattering amplitude of D Pi at the energy of the B mass can be calculated using Regge theory. Recent papers have used this to calculate the final state strong phases in the decays B to D Pi. It is argued that while the Regge amplitude can yield an absorption correction to the decay rate, it is not useful for determining the strong phase.
The observed strong phase difference of 30^{o} between I=(3/2) and I=(1/2) final states for the decay B to D Pi is analyzed in terms of rescattering like D^{∗}Pi to D Pi, etc. It is concluded that for the decay B^{o}to D^{+} Pi^{-} the strong p
Two sources of strong phases in the decays $B$ to $pipi$ are identified: (1) quasi-elastic scattering corresponding to intermediate states like $pipi$ and $rhorho$, (2) ``$cbar{c}$ corresponding to intermediate states like $Dbar{D}$ and $D^{*}bar{D}^
We present a model for the decay $D^+to K^-pi^+pi^+$. The weak interaction part of this reaction is described using the effective weak Hamiltonian in the factorisation approach. Hadronic final state interactions are taken into account through the $Kp

We extract the Glauber divergences from the spectator amplitudes for two-body hadronic decays $B to M_1 M_2$ in the $k_T$ factorization theorem, where $M_2$ denotes the meson emitted at the weak vertex. Employing the eikonal approximation, the diverg
