摘要
The perturbative unitarity bound is studied in the monojet process at LHC. The production of the dark matter is described by the low-energy effective theory. The analysis of the dark matter signal is not validated, if the unitarity condition is violated. It is shown that the current LHC analysis with the effective theory breaks down, at least, when the dark matter is heavier than O(100) GeV. Future prospects for root s = 14TeV are also discussed. The result is independent of physics in higher energy scales.
