We discuss the determination of the CKM angle $$\alpha$$α using the non-leptonic two-body decays $$B\rightarrow \pi \pi$$B→ππ, $$B\rightarrow \rho \rho$$B→ρρ and $$B\rightarrow \rho \pi$$B→ρπ using the latest data available. We illustrate the methods used in each case and extract the corresponding value of $$\alpha$$α. Combining all these elements, we obtain the determination $$\alpha _\mathrm{dir}={({86.2}_{-4.0}^{+4.4} \cup {178.4}_{-5.1}^{+3.9})}^{\circ }$$αdir=(86.2-4.0+4.4∪178.4-5.1+3… Expand
