Constraints upon the CKM angle phi_2 (alpha) from Belle

高能物理 - 实验 2019-08-14 v1

摘要

The Belle experiment has measured branching fractions and CP asymmetries for the charmless decays B0->pi+pi- and B0->rho+-pi-+. From these measurements, constraints upon the CKM angle phi_2 can be obtained. These constraints indicate that phi_2 is around 100 degrees.
