  • Jack Sarfatti Remember, the actual Higgs field is NOT a collection of real Higgs particles whizzing through space. On the contrary its a vacuum field made from coherent Glauber states of VIRTUAL Higgs particles. This is an important distinction none of the popular science writers understand very well.

    • Jack Sarfatti It's like a Bose-Einstein condensate yes, but not exactly the same of course. Bose-Einstein condensates of atoms are giant local quantum matter waves in which a huge number of real atoms have their centers of mass all in the same single particle "cell in phase space" of volume ~ (Planck's quantum of action)^3. Mathematically that quantum state is a Glauber coherent state in terms of the superposition of sharp number "Fock states" - or some distortion of it (e.g. squeezed states).

    • Jack Sarfatti m is the rest mass, which for leptons like electrons and quarks as well as W-bosons are proportional to the vacuum expectation value of the Higgs field Glauber type macro-quantum coherent state destruction second-quantized field operator for large numbers of virtual Higgs particles that are off their own mass shells. That is, the virtual Higgs particles that collectively give rest masses m to leptons, quarks & W do not themselves obey the above equation.
    • Jack Sarfatti The larger rest masses M of hadrons like protons require additional physics (QCD) and come from the kinetic motion of confined quarks and the virtual particle plasma they are immersed in.
  • Jack Sarfatti What the LHC shows are real Higgs particles that are incoherent excitations out of the coherent vacuum Higgs field. It is only the coherent vacuum field of these virtual off-mass-shell Higgs particles in huge numbers all in the same single-particle state that gives rest mass to the real W bosons and the real leptons and real quarks.

Hi, Dr. Jack. Question: Do you think the LHC detected a fundamental scalar Higgs or just a composite Higgs?
Jack Sarfatti: No way to decide that yet. Still many more years of experimental work needed. Lenny Susskind has a "technicolor" model in which the Higgs is composite. This great accomplishment was only the end of the beginning.

    • Russell Clark I wonder if there is a place for a composite Higgs in induced gravity theory. And if the LHC detectors could presently differentiate a fundamental scalar Higgs from a composite Higgs or, if this must remain a question of interpretation until the next LHC upgrade. Oh, and I don't blame you, Doc, if you smack me on the head and send me off to the Sarfatti Physics forums, LOL!

    • Jack Sarfatti ‎"Elementary Higgs bosons perform another important task. In the Standard Model, quarks and leptons are necessarily massless because they transform under SU(2) ⊗ U(1) as left-handed doublets and right-handed singlets. The Higgs doublet couples to these fermions. When it develops its vacuum expectation value, it transmits this electroweak breaking to the quarks and leptons, giving them their observed masses. (In general, electroweak-eigenstate fermions are not mass eigenstates, so this process also induces the mixing matrices observed in charged-current weak interactions.)"

    • Jack Sarfatti Composite Higgs Search at the LHC
      Jose Ramon Espinosa, Christophe Grojean, Margarete Mühlleitner
      (Submitted on 16 Mar 2010)
      The Higgs boson production cross-sections and decay rates depend, within the Standard Model (SM), on a single unknown parameter, the Higgs mass. In composite Higgs models where the Higgs boson emerges as a pseudo-Goldstone boson from a strongly-interacting sector, additional parameters control the Higgs properties which then deviate from the SM ones. These deviations modify the LEP and Tevatron exclusion bounds and significantly affect the searches for the Higgs boson at the LHC. In some cases, all the Higgs couplings are reduced, which results in deterioration of the Higgs searches but the deviations of the Higgs couplings can also allow for an enhancement of the gluon-fusion production channel, leading to higher statistical significances. The search in the H to gamma gamma channel can also be substantially improved due to an enhancement of the branching fraction for the decay of the Higgs boson into a pair of photons.

With all the necessary caution, it looks to me that we are at a branching point: the observation of this new particle indicates the path for the future towards a more detailed understanding of what we're seeing in the data."

    • Jack Sarfatti The weight of evidence is that the Higgs is elementary not composite as in technicolour theory, i.e. Standard Model is looking good. Of course, this could change, but at the moment that's the best estimate.

      Real free (zero rest mass) particle quantum states excited out of the vacuum have spherical wave modes ~ (1/r)e^if(t +- n.r/c) where n is the unit propagation vector, r is the radial vector from the point source to the point of position measurement. - sign for retarded waves propagating from present to future, - sign propagating from present back to the past - in the Dirac-Stueckleberg-Wheeler-Feynman theory (http://en.wikipedia.org/wiki/Ernst_Stueckelberg  ). In contrast, the corresponding spherical mode wave functions for virtual particles inside the vacuum have the form (1/r)e^i(ft +- k.r) where there is no relationship between frequency f and wave vector k. When there is rest mass, the "mass shell" relationship is more complicated for real particles
