PlanetPhysics/Higgs Boson a Neutral Scalar Particle

Higgs boson
The following is a link to a \htmladdnormallink{simplified demonstration using $$Mathematica^{TM}$$ for the generation of the Higgs boson}{http://demonstrations.wolfram.com/TheHiggsParticle/}, a (hypothetical) fundamental, neutral scalar particle $$H^0$$ which is supposed to be detected `soon' by one of the two Tevatron, particle accellerators presently in operation.

The oversimplified simulation is in the form of a color animation with the $$Mathematica^{TM}$$ Player (which is also a free download that does not save however). The simulated experiment seems to indicate that unless the available energy is not greater than about 120 GeV the Higgs boson is not readily observed. Feynman diagrams for the generation of the Standard Model Higgs boson are also shown in this demo.

The potential for discovering the scalar Higgs boson is recently discussed for the CMS experimental setup. Other hypothetical particles,`neutralinos', "could also emerge from high--energy collisions at the Large Hadron Collider in Europe or the Tevatron collider in the United States. Supersymmetry theories predict that neutralinos are closely related to the well-known carriers of the electroweak force--photons and (W,Z) bosons--and also to Higgs bosons. Whether the LHC will produce neutralinos, and what the experimental signatures of these particles look like, depends on how neutralinos interact with ordinary matter. If the LHC experiments discover neutralinos, a main goal will be to measure the relationship between neutralinos and the electroweak force carriers. This will allow theorists to calculate the amount of dark matter produced in the big bang and how it relates to the dark matter observed throughout the universe today" (cf. Gordon Kane of the University of Michigan in a downloadable pdf).

According to the current Standard Model theory, various particles are supposed to acquire mass only via their interactions with the neutral scallar Higgs boson, $$H^0$$. (A Nobel prize has already been predicted for such a hypothetical discovery that would close the gap between the current Standard Model theory and experimental, High energy physics. There have already been unconfirmed rumors of Higgs bosons generated at the Fermilab Tevatron in US.)
