Abstract

We report the recent phi2/alpha results from Belle with KEKB accelerator and Babar with PEP-II accelerator. The analysis of B->pi pi, B->rho rho and B->rho pi are included in this report. These b->u u_bar d decay modes are related to the CKM angle phi2/alpha and the method of phi2/alpha extraction of corresponding decay are also included. After combining all the decay modes, the constraint of phi2/alpha is 100.2+15.0-8.8 degree.
