distribution for the SM4 signature (blue) and for the 4G2HDMI signature (red), for a set of 7 TeV LHC events with . For both signatures, GeV is assumed. The peak of the distribution of for the SM4 signature is around , while for the new signature the peak is shifted to a significantly lower value coinciding with the peak of the background.
