Studies of the resonance structure in $$D^{0} \rightarrow K^\mp \pi ^\pm \pi ^\pm \pi ^\mp $$ D 0 → K ∓ π ± π ± π ∓ decays

Amplitude models are constructed to describe the resonance structure of D 0 K - + + -and D 0 K + - - + decays using pp collision data collected at centre-of-mass energies of 7 and 8 TeV with the LHCb experiment, corresponding to an integrated luminosity of 3.0 f b -1 . The largest contributions to both decay amplitudes are found to come from axial resonances, with decay modes
