ABSTRACT
The standard SU ( 2 ) L × U ( 1 ) Y https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429494062/4af1a3a3-6c2d-45d0-b33d-a81d6d438301/content/eq3309.tif"/> gauge model provides a remarkably successful description of the observed weak interactions. An essential component of the model is the SU(2) scalar doublet which is responsible for the spontaneous breakdown of the gauge symmetry. After electroweak symmetry breaking, there remains a single neutral scalar particle—the Higgs boson—as discussed in Chapter 2. The search for this elusive Higgs boson is one of the most important efforts for present and future accelerators, since its discovery would be the definitive confirmation of the model.
