$B\to \pi \pi$ decays and effects of the next-to-leading order contributions

Ya-Lan Zhang, Xue-Yan Liu, Ying-Ying Fan +2

In this paper we perform a systematic study for the three $B\to ({\pi }^{+}{\pi }^{-},{\pi }^{+}{\pi }^0,{\pi }^0{\pi }^0)$ decays in the perturbative QCD (pQCD) factorization approach with the inclusion of all curr…
