Light-cone QCD sum rule approach for the $\Xi$ baryon electromagnetic form factors and the semileptonic decay Xi_c->Xi e^+nu_e

Abstract

The electromagnetic form factors of the Xi baryons and the semileptonic decay process Xi_c->Xi e^+nu_e are investigated in the frame work of the light-cone QCD sum rule method with Ioffe-type interpolating currents. Our estimates on the magnetic moments are $mu_{Xi^0}=-(1.75\pm0.21) mu_N and mu_{Xi^-}=-(1.01\pm0.11)mu_N. The decay width of the semileptonic process is expected to be Gamma(Ξ_c\to Ξe^+ν_e)=(6.17^{+2.24}_{-2.48})\times10^{-14}GeV. The results make sure that the adoption of this type interpolating current improve the calculations of the magnetic form factors and give more reliable prediction for the analysis of the semileptonic decay process.
