LHC 2012 Beyond Moriond: Hunt for Multi-Higgs

Authors: Frank Dodd Tony Smith Jr

Nobel laureate Steven Weinberg (quoted in New Scientist 7 March 2012) said: "One Higgs would be very sad ... If all we see at the LHC is one Higgs, it's not going to help us ... see clearly what the road ahead is ...” ...”. My view of the data from Tevatron and LHC presented at Moriond (7 Mar 2012 and (in version 2 of this paper) 11 Mar 2012) is that Steven Weinberg should be Very Happy. Instead of a single Standard Model Higgs at 125 GeV, I think the data indicates the following phenomena: 125 GeV - pion-type meson T0 (low-mass Tquark-antiUpquark); 126.5 GeV - pion-type meson T0c (low-mass Tquark-antiCharmquark); 136 GeV - SM Higgs (low state of 3-state Higgs); 195 GeV - SM Higgs (middle state of 3-state Higgs); 244 GeV - SM Higgs state near Higgs VEV (high state of 3-state Higgs). Matt Strassler in his 6 Dec 2011 guest post on Cosmic Variance proposed a flow chart for two phases in the LHC Hunt for Higgs: Phase 1 being Search for a Single Standard Model Higgs; Phase 2 including Search for 2 or more Higgs. My view is that Phase 1 has failed to clearly find a Single Standard Model Higgs so that the LHC should now in 2012 begin the Phase 2 Hunt for Multi-Higgs. Version 2 incorporates material from 11 Mar 2012 Moriond presentations. (References are included in the body of the paper and in linked material.)
