Science: W Boson much heavier than SM predicts?

  • Quote

    Abstract

    The mass of the W boson, a mediator of the weak force between elementary particles, is tightly constrained by the symmetries of the standard model of particle physics. The Higgs boson was the last missing component of the model. After observation of the Higgs boson, a measurement of the W boson mass provides a stringent test of the model. We measure the W boson mass, MW, using data corresponding to 8.8 inverse femtobarns of integrated luminosity collected in proton-antiproton collisions at a 1.96 tera–electron volt center-of-mass energy with the CDF II detector at the Fermilab Tevatron collider. A sample of approximately 4 million W boson candidates is used to obtain MW=80,433.5±6.4stat±6.9syst=80,433.5±9.4 MeV/c2
    , the precision of which exceeds that of all previous measurements combined (stat, statistical uncertainty; syst, systematic uncertainty; MeV, mega–electron volts; c, speed of light in a vacuum). This measurement is in significant tension with the standard model expectation.

    As the W-Boson is related to the weak force, could this new data open loopholes where LENR theories could fit in?

  • Standard Model doesn't actually predict mass of any particle by itself. It means, when physicists say that “the W mass is too large” then they roughly mean that “the ratio of the W mass to the Z mass is too large".


    Most of deviations from Standard Model recently observed arise from Yukawa interaction, i.e. short distance analogy of Casimir force between quarks (or even shorter distance analogy of Allais effect and similar gravitational shielding between massive objects). Nearby heavy particles create a shadow of vacuum fluctuations between them, which contributes to their perceived mass. It may be possible that newer collider experiments utilizing higher energies and luminosities enforce this shielding effect more than previous ones. From AWT theory follows it should manifest itself preferably for collinear pairs of particles and/or particle clusters, which is the case of so-called Hungarian boson.

  • BTW similar discrepancy has been found - but promptly swept under the carpet - for Higgs boson observations. Higgs boson is indeed all neutral - but similarly to W/Z bosons its mass differs depending on when its formed during photon decay (like Z-boson) or during charged particles collisions (like W-/W+ bosons). So that nothing really new is here, but mainstream physics struggling to vindicate Peter Higgs model and LHC investments averaged both results into a single one by pretending, that Higgs particle found is exactly this one "expected" by Standard Model, so that Nobel prize appraisal would run smoothly.

    AWT explanation of this discrepancy is, when charged particles collide, then the mass distribution resembles elongated dumbbell, so that shielding dark matter effects (analogous to Allais effect during eclipses) may apply there. During diphoton decays the particle intermediate has merely spherical shape, which exhibits smaller dark matter / scalar wave effect. If this discrepancy resembles the Hubble constant discrepancy for you, then you're on the right track - it's also dark matter effect.

  • Regular visitors of this forum probably know, that analogous effect may participate to cold fusion mechanism, where I suggested it also runs through linear arrangement of atoms colliding in chains. Along these chains the scalar wave shielding gets intensive and such an atoms can temporarily form long tubes of Casimir vacuum, which serve like waveguides for nuclear products, forcing them to get absorb in atom nuclei and prohibiting them in escaping into outside without dissipation into heat.

  • Dear participants of the discussion, let me share with you my thoughts on the mechanism of symmetry breaking of the standard model of elementary particles.


    Since the Lie algebra of the group SU(2) is realized as the algebra of tangent vector fields of the torus, the mechanism of symmetry breaking is realized as an addition of the vector field of evolution, which is equivalent to an evolutionary change in the ratio of the radii of the defining circles of the torus.


    Thus, the vortex model of the electron meets the requirements of the standard model. However, it should be understood that the vector field of our vortex is formed in the dual to (x,t) space (x*,t*)


    At the same time, the vector field should be interpreted as the acceleration field of moving matter.
