We present the results of a search for new, heavy particles that decay at a signiﬁcant distance from theirproduction point into a ﬁnal state containing charged hadrons in association with a high-momentummuon. The search is conducted in a pp-collision data sample with a center-of-mass energy of 7 TeV andan integrated luminosity of 33 pb−1collected in 2010 by the ATLAS detector operating at the LargeHadron Collider. Production of such particles is expected in various scenarios of physics beyond thestandard model. We observe no signal and place limits on the production cross-section of supersymmetricparticles in an R-parity-violating scenario as a function of the neutralino lifetime. Limits are presentedfor different squark and neutralino masses, enabling extension of the limits to a variety of other models.
