Title: Measurements of the Branching Fractions of the Semileptonic Decays Ξ c 0 Ξ + ν and the Asymmetry Parameter of Ξ c 0 Ξ π +

Abstract

Using data samples of 89.5 and 711 fb-1 recorded at energies of √s = 10.52 and 10.58 GeV, respectively, with the Belle detector at the KEKB e+e- collider, we report measurements of branching fractions of semileptonic decays Ξ$$^{0}_{c}$$ → Ξ-ℓ+ν (ℓ = e or μ) and the CP-asymmetry parameter of Ξ$$^{0}_{c}$$ → Ξ-π+ decay. The branching fractions are measured to be B(Ξ$$^{0}_{c}$$ → Ξ-e+νe) =(1.31 ± 0.04 ± 0.07 ± 0.38)% and B(Ξ$$^{0}_{c}$$ → Ξ-μ+νμ) = (1.27 ± 0.06 ± 0.10 ± 0.37)%, and the decay parameter αΞπ is measured to be 0.63 ± 0.03 ± 0.01 with much improved precision compared to the current world average. The corresponding ratio B(Ξ$$^{0}_{c}$$ → Ξ-e+νe)/B(Ξ$$^{0}_{c}$$ → Ξ-μ+νμ) is 1.03 ± 0.05 ± 0.07, which is consistent with the expectation of lepton flavor universality.
