Search for Supersymmetric Particles WANYU YE, Department of Physics and Astronomy, Stony Brook University — Supersymmetry (susy) is a symmetry that relates the elementary particles of
one spin to another that differs by half a unit of spin. Every boson has
its fermion superpartner and vice versa under this symmetry. There
is no direct evidence of supersymmetry yet, indicating it is a broken
symmetry allowing the sparticles to be heavy. Supersymmetry features
the potential as a grand unification theory. It also provides an effective
solution to the infamous hierarchy problem in the standard model. In
todays talk I will introduce the concept of supersymmetry and consequent particles in the MSSM (minimal supersymmetric standard model)
framework. I will present the motivations, advantages and several phenomenological implications of supersymmetry. Different susy breaking
scenarios predicte the mass spectra of sparticles. The R-parity indicates
the existence of the lightest supersymmetric particle (LSP), which makes
an attractive candidate for the dark matter. Contemporary cosmological observations provide an estimation in the cross sections of possible
stable particles in the universe. The Large Hadron Collider (LHC) at
CERN will conduct direct and indirect searches for susy particles.
