With only the tree-level operator, the decay of 
is predicted to be one order smaller than the experimental data. The QCD penguin effects should be taken into account. In this paper, we explore the one-loop QCD corrections to the decay of within the framework of QCD factorization approach. For the baryon system, the diquark approximation is adopted. The transition hadronic matrix elements between 
and p are calculated in the light-front quark model. The branching ratio of is predicted to be about 
, which is consistent with experimental data 
. The CP violation is about 5 % in theory.
