Analysis of the semileptonic decay Λ_c->ne^+ν_e

Abstract

The semileptonic weak decay process of the ${\Lambda }_c$ baryon to the neutron ${\Lambda }_c\to n{e}^{+}{\nu }_e$ is examined. The transition form factors are investigated with light-cone QCD sum rules. The differential decay width is obtained in the dynamical region by fitting the sum rules-allowed results with the dipole formula. The total decay width and the branching ratio are estimated to be $Γ(Λ_c\rightarrow ne^+ν_e)=(8.57\pm0.41)\times10^{-15}\,\mbox{GeV}$ and $\mbox{Br}(Λ_c\rightarrow ne^+ν_e)=0.26\pm0.01\%$, respectively.
