  1. A New Way to Detect the Higgs S. Reucroft Northeastern University, Boston Work done with Y.N. Srivastava, J. Swain and A. Widom 1. hep-ph/0509151 and Euro. Phys. J. C (theory) 2. hep-ph/0511233 (experimental consequences) ≥TeV Workshop August 28, 2006

  2. Standard ways to look for Higgs Really only two techniques: 1) Direct searches; 2) Indirect appearances in loops with heavy particles (radiative corrections). NOT EASY ≥TeV Workshop August 28, 2006

  9. A New Method • Based on a Very Simple Idea • Look for the Higgs FIELD instead of the Higgs PARTICLE • Problem: Higgs is very massive  very short range Higgs field • A Particle very close to the Source of a Higgs Field will experience a Mass Adjustment • Look at the Effect on Pairs of Massive Particles near Pair Threshold ≥TeV Workshop August 28, 2006

  10. hep-ph/0509151 = Euro. Phys. J. C  ≥TeV Workshop August 28, 2006

  11. Z Mass Plots from L3 at LEP2

  12. Summary • Look at Pairs of Massive Particles Near Threshold • Higgs Field Causes Mass Shifts • Experimentally Difficult and Delicate Technique (Like all Higgs Techniques) • Complements Higgs Boson Searches • New Powerful Higgs Tool at LHC, ILC,…. • Unlike Direct and Indirect Higgs Boson Searches, It Provides Unambiguous Proof of Presence or Absence of Higgs Field ≥TeV Workshop August 28, 2006
