CP-violating observables of four-body $$B_{(s)} \rightarrow (\pi \pi )(K\bar{K})$$ B ( s ) → ( π π ) ( K K ¯ ) decays in perturbative QCD
Abstract In this work, we investigate six helicity amplitudes of the four-body $$B_{(s)} \rightarrow (\pi \pi )(K\bar{K})$$ B ( s ) → ( π π ) ( K K ¯ ) decays via an angular analysis in the perturbative QCD (PQCD) approach. The $$\pi \pi $$ π π invariant mass spectrum is dominated by the vector reso...
