N2 - We study LHC phenomenology of mirage mediation scenario in which anomaly and modulus contributions to soft SUSY breaking terms are comparable to each other. A Monte Carlo study of mirage mediation, with model parameters α ≤ 1, M0 ≤ 500 GeV, nM ≤ 1/2, nH ≤ 1 and tanβ ≤ 10, is presented. It is shown that masses of supersymmetric particles can be measured in a model independent way, providing information on SUSY breaking sector. In particular, the mass ratio of gluino to the lightest neutralino for the benchmark scenario is determined to be 1.9 m/m 10 3.1, well reproducing theoretical input value of m/m10 2.5 which is quite distinctive from the predictions m/m106 of other SUSY scenarios in which gaugino masses are unified at the GUT scale. The model parameters of mirage mediation can be also determined from various kinematic distributions.
