  We studied the production of single chargino$\tilde{\chi}_1^{\pm}$
accompanied by $\mu^{\mp}$ lepton via gluon-gluon fusion at the LHC. The
numerical analysis of their production rates is carried out in the mSUGRA
scenario with some typical parameter sets. The results show that the cross
sections of the $\tilde{\chi}_1^{\pm}\mu^{\mp}$ productions via gluon-gluon
collision are in the order of $1 \sim 10^{2}$ femto barn quantitatively at the
CERN LHC, and can be competitive with production mechanism via quark-antiquark
annihilation process.
