Amplitude analysis of Bs0 → KS0 K ± π ∓ decays

The first untagged decay-time-integrated amplitude analysis of B 0s → K 0SK±π∓ decays is performed using a sample corresponding to 3.0 fb−1 of pp collision data recorded with the LHCb detector during 2011 and 2012. The data are described with an amplitude model that contains contributions from the i...
