- Аннотация: The first untagged decay-time-integrated amplitude analysis of B0s → K0S K±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 intermediate resonances K∗(892)0,+, K∗2 (1430)0,+ and K∗0 (1430)0,+, and their charge conjugates. Measurements of the branching fractions of the decay modes B0s → K∗(892)±K∓ and B0s→K∗(—)(892)0K0(—) are in agreement with, and more precise than, previous results. The decays B0s → K∗0 (1430)±K∓ and B0s→K∗0(—)(1430)0K0(—) are observed for the first time, each with significance over 10 standard deviations.
