“…Those uncertainties that do not cancel are summarized in Table III (I) PID. To account for the difference between data and MC simulation, we study a series of control samples of e + e − → K [49] to determine the K ± and π ± PID efficiencies. The detection efficiencies for the four Λ + c decay modes are recalculated after reweighting the corresponding MC samples on an event-by-event basis according to the momentumdependent efficiency differences between data and MC simulations.…”

Based on a sample of 4.4 fb −1 of e + e − annihilation data collected in the energy region between 4.6 GeV and 4.7 GeV with the BESIII detector at BEPCII, two singly Cabibbo-suppressed decays) is measured to be 0.0361 ± 0.0073(stat.) ± 0.0005(syst.), and the ratio of) is measured to be 0.0106 ± 0.0031(stat.) ± 0.0004(syst.). After taking the world-average branching fractions of the reference decay channels, the branching fractions B(Λ + c → Σ 0 K + ) and B(Λ + c → Σ + K 0 S ) are determined to be (4.7±0.9(stat.)± 0.1(syst.) ± 0.3(ref.)) × 10 −4 and (4.8 ± 1.4(stat.) ± 0.2(syst.) ± 0.3(ref.)) × 10 −4 , respectively. The branching fraction of the Λ + c → Σ + K 0 S decay is measured for the first time.

“…The decay D + s → K − K + π + π 0 is a Cabibbo-favored decay (the inclusion of charge conjugate reactions is implied throughout this paper). Due to its large branching fraction (BF), it is usually selected as a "tag mode" for the measurement of other decays of the D + s meson [2][3][4][5][6][7]. However, the BF of the D + s → K − K + π + π 0 decay has a large systematic uncertainty due to the poor knowledge of intermediate state processes [8,9].…”

We present the first amplitude analysis of the decay D + s → K − K + π + π 0 using data samples of 6.32 fb −1 recorded with the BESIII detector between 4.178 and 4.226 GeV. More than 3000 events selected with a purity of 97.5% are used to perform the amplitude analysis, and nine components are found necessary to describe the data. Relative fractions and phases of the intermediate decays are determined. With the detection efficiency determined by the results of the amplitude analysis, we measure the branching fraction of D + s → K − K + π + π 0 decay to be (5.42 ± 0.10stat. ± 0.17syst.)%.
