Using the most recent determinations of several theoretical and experimental parameters, we update the Unitarity Triangle analysis in the Standard Model. The basic experimental constraints come from the measurements of epsilon_k, Vub/Vcb and Delta m_d, the limit on Delta m_s, and the measurement of the CP asymmetry in the B sector through the J/psi K^0 channel. In addition we also include in our analysis the direct determination of sin 2 alpha, gamma and sin(2 beta + gamma) from the measurements of new CP-violating quantities, recently coming from the B-Factories. We also discuss the opportunities offered by improving the precision of the measurements of the various physical quantities entering in the determination of the Unitarity Triangle parameters. The results and the plots presented in this paper can be also found at http://www.utfit.org, where they are continuously updated with the newest experimental and theoretical results.
