Evidence for New particle physics model

Evidence for particles beyond the standard model of physics The Next-to-minimal supersymmetric standard model seems to fit the data that has been found. We will not know for sure until about 2009 when enough data has been gathered by the new Large Hadron Collider (LHC) that start this year.

Although He and colleagues showed in an earlier paper that the HyperCP result may be explained by the SM if there is no new particle, the implications of a new particle are considerable. If scientists find that particle X is indeed a new particle belonging to a different model, the breakdown of the SM would open up new doors for future investigations in many areas, and possibly answer many questions unanswered by the SM.

”The presence of the superpartners results in the cancellation of the large quantum corrections, leading to a Higgs mass at the desired level,” he said. “The minimal version of such models is called the Minimal Supersymmetric Standard Model (MSSM). The MSSM is a very attractive model in many ways, but it does not address the question of why the electroweak scale is much smaller than the Planck scale to begin with—this is the so-called mu problem.

“Interestingly, the Next-to-Minimal Supersymmetric Standard Model (NMSSM) solves this problem by adding a set of two particles to the MSSM in such a way that the electroweak scale can be naturally small. The NMSSM has been extensively studied in the literature and has many other interesting features. It is therefore a well-motivated model.”

Although physicists need to be careful before discarding an old model and confirming a new model. I do not have that restriction. I am willing to start favoring the NMSSM model now and if the evidence starts looking could for confirmation was still looking good in 2008 would be willing to bet that is way it will break.
