Perspectives in High-Energy Physics

Abstract

A personal view of current prospectives in particle physics is presented, inspired by the contributions to this meeting. Particular emphasis is laid in precision tests of the Standard Model and the search for the Higgs boson, on probes of CP violation, on speculations about possible physics beyond the Standard Model, on neutrino masses and oscillations, on the quest for supersymmetry, on opportunities @ future accelerators, and on the ultimate phenomenological challenge offered by the quest for a Theory of Everything.

On the quest for unification simplicity and antisimplicity

“…For a recent overview see e.g. [14]. We consider the 'once local' form of the algebra of N susy charges [15] …”

“…defined in the MS scheme and normalized to a common Casimir operator of one chiral fermion family are defined as We thus pick up the three coupling constants at the scale 14).…”

Linear collider workshop 2000 summary

“…If supersymmetry is to produce EWSB and yield the observed Z mass without 'excessive' fine tuning, then it follows that we are likely to produce the lighter chargino and neutralinos, and the sleptons, at a 500 GeV linear collider [10]. If the LSP is to provide the candidate for dark matter in the universe, light sparticles are preferred (though some of the parameter space yielding Susy dark matter requires raising the LC energy to 1 TeV or a little higher [18]). If Susy is to provide the CP violation needed for cosmic baryon asymmetries, light sparticles are favored.…”
