| Outline of Final Research Achievements |
Helicity amplitudes are useful for processes in high energy physics, especially when parity-violating interactions are involved. We have developed a formalism to evaluate helicity amplitudes of processes including particles with spin higher than one in terms of Wigner's d functions. We examine new physics processes at the LHC collider in models including several scenarios in the supersymmetric standard model. Limits on the scalar top quark mass is derived using ATLAS data from LHC in the natural SUSY scenario. We also study models with pseudo-goldstinos and find that future high-luminosity LHC will be able to detect production of neutralinos/charginos decaying to pseudo-goldstinos emitting W, Z, or Higgs bosons.
