In some new physics models, there exists a long-lived colored particle. Although such a particle is expected be discovered by studying the muon-like tracks, it is not easy to discriminate hadronic events from leptonic ones at the Large Hadron Collider. We focus on the charged track events associated with a single hard gluon jet. They are sensitive to the colored long-lived particle and found to be almost free from the background after applying the velocity cut. We also study the the process to probe properties of the particle.
