The search is performed using an unbinned model-independent method known as the energy test that probes local CP violation in the phase space of the decays. The data analysed correspond to an integrated luminosity of 5.4 fb(-1) collected in proton-proton collisions by the LHCb experiment at a centre-of-mass energy of root s = 13TeV, amounting to approximately 950 thousand and 620 thousand signal candidates for the D-0 -> (KSK-)-K-0 pi(+) and D-0 -> (KSK+)-K-0 pi(-) modes, respectively. The method is validated using D-0 -> K-pi(+)pi(-)pi(+) and D-0 -> K-S(0)pi(+)pi(-) decays, where CP-violating effects are expected to be negligible, and using background-enhanced regions of the signal decays. The results are consistent with CP symmetry in both the D-0 -> (KSK-)-K-0 pi(+) and the D-0 -> (KSK+)-K-0 pi(-) decays, with p-values for the hypothesis of no CP violation of 70{\%} and 66{\%}, respectively.", optnote="WOS:001190072500001", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=6124), last updated on Fri, 24 May 2024 12:38:51 +0000", issn="1029-8479", doi="10.1007/JHEP03(2024)107", opturl="https://arxiv.org/abs/2310.19397", opturl="https://doi.org/10.1007/JHEP03(2024)107", language="English" }
