A precise measurement of the angle alpha in the CKM
triangle is very important for a complete test of Standard Model.
A theoretically clean method to extract
alpha is provided by
B0 --> rho pi decays. Monte Carlo simulations to obtain the BTeV
reconstruction efficiency and to estimate the signal to background ratio
for these decays were performed. Finally the time-dependent Dalitz
plot analysis, using the isospin amplitude formalism for tree and
penguin contributions, was carried out.
It was shown that in
one year of data taking BTeV could achieve an accuracy on alpha
better than 5o.
