    38    * In the plots %$H_T=\sum ||p_T^{vis}|| + E_T^{miss}$%.
     38   * In the plots $H_T=\sum ||p_T^{vis}|| + E_T^{miss}$.
    3939   * A SM-like  Z' would decay (more or less democratically) into: jet jet (uu~,cc~,dd~,ss~,bb~), t tbar (tt~), lept+lept- (e+e-,mu+mu-,ta+ta-), neutrino anti-neutrino (ve ve~,vm vm~,vt vt~). It could also have couplings to SM W and Z, and in that case would decay in to ZZ and W+W-.
    4040   * An Higgs couple to particles with a strength which is proportional to the particle masses. A SM-like  heavy H would decay in to t tbar (tt~), W+W-, ZZ.
