Search for CP violation in Ξ+cpKπ+ decays using model-independent techniques / LHCb Collaboration
A first search for CP violation in the Cabibbo-suppressed Ξ+cpKπ+ decay is performed using both a binned and an unbinned model-independent technique in the Dalitz plot. The studies are based on a sample of proton-proton collision data, corresponding to an integrated luminosity of 3.0 fb1, and collected by the LHCb experiment at centre-of-mass energies of 7 and 8 TeV.

Measurement of the branching fraction of the decay B0sK0SK0S / LHCb Collaboration
A measurement of the branching fraction of the decay B0sK0SK0S is performed using proton-proton collision data corresponding to an integrated luminosity of 5 fb1 collected by the LHCb experiment between 2011 and 2016. The branching fraction is determined to beB(B0sK0SK0S)=[8.3±1.6(stat)±0.9(syst)±0.8(norm)±0.3(fs/fd)]×106, where the first uncertainty is statistical, the second is systematic, and the third and fourth are due to uncertainties on the B0ϕK0S branching fraction and the ratio of hadronization fractions fs/fd [...]

Rates of B0sDsμ+νμ and B0sDsμ+νμ decays are analyzed using hadronic form-factor parametrizations derived either by Caprini, Lellouch and Neubert (CLN) or by Boyd, Grinstein and Lebed (BGL). [...]

In the dilepton mass-squared range 0.1<q2<6.0 GeV2/c4 and the pK mass range m(pK)<2600 MeV/c2, the ratio of branching fractions is measured to be R1pK=1.17+0.180.16±0.07, where the first uncertainty is statistical and the second systematic.

Isospin amplitudes in Λ0bJ/ψΛ(Σ0) and Ξ0bJ/ψΞ0(Λ) decays / LHCb Collaboration
Ratios of isospin amplitudes in hadron decays are a useful probe of the interplay between weak and strong interactions, and allow searches for physics beyond the Standard Model. We present the first results on isospin amplitudes in b-baryon decays, using data corresponding to an integrated luminosity of 8.5 fb1, collected with the LHCb detector in pp collisions at center of mass energies of 7, 8 and 13 TeV.
