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/ and Euro. Phys. J. C (theory)
2. hep-ph/ (experimental consequences)

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

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

15. Z Mass Plots from L3 at LEP2

20. 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
