In supersymmetric theory, the sfermion-fermion-gaugino interactions convert a sfermion into a fermion in the same chiral multiplet. The effect appears as the asymmetry between m(jl{sup +}) and m(jl{sup -}) distributions at the CERN Large Hadron Collider where jets (j) and leptons (l{sup {+-}}) arise from the cascade decay q{yields}q{chi}{sub 2}{sup 0}{yields}qll. Furthermore, the decay branching ratios and the charge asymmetries in m(jl{sup {+-}}) distributions are flavor nonuniversal due to the l{sub L} and l{sub R} mixing. When tan{beta} is large, the nonuniversality between e and {mu} becomes O(10)% level. We perform a Monte Carlo simulation for some minimal supergravity benchmark points to demonstrate the detectablity.
