Abstract
The first untagged decay-time-integrated amplitude analysis of B 0 s → K 0S 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 B 0 s → K*(892)±K∓ and \( {B}_s^0\to \overset{\left(\hbox{---} \right)}{K^{*}}{(892)}^0\overset{\left(\hbox{---} \right)}{K^0} \) are in agreement with, and more precise than, previous results. The decays B 0 s → K *0 (1430)±K∓ and \( {B}_s^0\to \overset{\left(\hbox{---} \right)}{K_0^{*}}{(1430)}^0\overset{\left(\hbox{---} \right)}{K^0} \) are observed for the first time, each with significance over 10 standard deviations.
