Study of four-body decays $$B_{(s)} \rightarrow (\pi \pi )(\pi \pi )$$ B ( s ) → ( π π ) ( π π ) in the perturbative QCD approach
Abstract In this work, we make a systematical study on the four-body $$B_{(s)} \rightarrow (\pi \pi )(\pi \pi )$$ B ( s ) → ( π π ) ( π π ) decays in the perturbative QCD (PQCD) approach, where the $$\pi \pi $$ π π invariant mass spectra are dominated by the vector resonance $$\rho (770)$$ ρ ( 770 )...
