Abstract: We study the phenomenology of the heavy charged gauge boson and obtain the lower bounds on its mass with the early LHC data at 7 TeV center-of-mass energy in the nonuniversal gauge interaction model, in which the electroweak SU(2) gauge group depends upon the fermion family. We found that the direct bound with the early data of the LHC is already better than the indirect bound on the mass of the boson. [Copyright &y& Elsevier]

We investigate a squark cascade decay, i.e. $\tilde q_L \rightarrow q\tilde\chi_2^0\rightarrow q Z\tilde\chi_1^0 \rightarrow qll\tilde\chi_1^0$. It is shown that some information on the mass and spin of the supersymmetric particles might be obtained from the cascade decay chain at the Large Hadron Collider at CERN. [ABSTRACT FROM AUTHOR]
