Amplitude analysis of $B^+ \!\to K^+ π^+ π^-$ decays

LHCb collaboration, R. Aaij, M. Abdelfatah, A. S. W. Abdelmotteleb et autres

The branching fractions and quasi-two-body $C\!P$-violating asymmetries of intermediate states obtained through an amplitude analysis of the charmless three-body decay $B^+ \!\to K^+ π^+ π^-$ are reported. The analysis is based on $pp$ collision data at centre-of-mass energies $\sqrt{s}=7$ and $8\,\text{TeV}$ recorded …
