Taking a closer look at LHC
Supersymmetry (SUSY) is a proposed property of the universe. It is one of the best motivated extensions of the Standard Model, so the study of SUSY is a primary goal of the LHC.
Supersymmetry requires every type of particle to have an associated supersymmetric particle, called its superpartner. The superpartner is a heavy replica of a particle, with one other significant difference. All particles are classed as either fermions or bosons. A particle belonging to one class has a superpartner in the other, thereby "balancing the books" and making nature more symmetric. For example, the superpartner of an electron (a fermion) is called a selectron (a boson).
|These supersymmetric particles, or sparticles,have the same charge but opposite spin to the particles we’re familiar with, such as photons and electrons.
Supersymmetry describes a new image of our universe formed of pairs of particles, but we can currently see only one partner from each pair. The unseen particles might be the source of the mysterious "dark matter" in galaxies. Although superpartners have not yet been observed in nature, they might soon be produced in particle accelerators like LHC at CERN.
Supersymmetry, specifically a version called the minimal supersymmetric model, achieves the grand unification more naturally, with far less fine-tuning. The theory predicts five Higgs bosons of different masses, which makes the process by which the universe gets its mass more complicated than that laid out by the standard model with its single Higgs.
