Nature of problem:
Simulation programs are required to compare theoretical models in particle physics with present and future data at particle colliders. SPICE determines the masses and decay branching ratios of supersymmetric particles in theories with lepton flavor violation. The inputs are the parameters of any of several standard flavor-conserving supersymmetric models, supplemented by flavor-violating parameters determined, for example, by horizontal flavor symmetries. The output are files that may be used for detailed simulation of supersymmetric events at particle colliders.
Simpson's rule integrator, basic algebraic computation.
SPICE interfaces with SOFTSUSY and SUSYHIT to produce the low energy sparticle spectrum. Flavor mixing for sleptons and sneutrinos is fully implemented; flavor mixing for squarks is not included.
< 1 minute. Running time is dominated by calculating the possible and relevant three-body flavor-violating decays of sleptons, which is usually 10-15 seconds per slepton.
