Study of the slepton nonuniversality at the CERN large hadron collider

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(+)) and m(jl(-)) distributions at the CERN Large Hadron Collider where jets (j) and leptons (l(+/-)) arise from the cascade decay q-->qchi(2)(0)-->qll. Furthermore, the decay branching ratios and the charge asymmetries in m(jl(+/-)) distributions are flavor nonuniversal due to the l(L) and l(R) mixing. When tanbeta 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.
