In SUSY QCD, a mass of left-handed squark is generally not the same as that of right-handed squark. Therefore, parity can be violated in QCD process by quark-squark-gluino vertexes. We focus on this parity violation, and discuss following two topics. 1. A discrimination between SUSY and UED. SUSY and UED are promising candidates beyond the SM. It is important to experimentally distinguish one from the other. We make a proposal to discriminate SUSY from UED at the LHC by focusing on the parity violation without discovering any new particles. 2. A bound for left-right degeneracy between squark masses. Since any parity violations have not been discovered in QCD, non-degeneracy bounds should be obtained between left- and right-handed squarks. We try to estimate the bounds by an investigation of charmonium decay and nucleon interactions. |
