It is possible that the electroweak scale is low due to the fine-tuning of microscopic parameters, which can result from selection effects. The experimental discovery of new light fundamental scalars other than the Standard Model Higgs boson would se

In the minimal supersymmetric model (MSSM), the tree-level value of the charged-Higgs-boson mass must be larger than {ital m}{sub {ital W}}. When one-loop radiative corrections are incorporated, we find that {ital m}{sub {ital H}}{sup +}{lt}{ital m}{

In two-Higgs-doublet models, the ${H}^{\ifmmode\pm\else\textpm\fi{}}{W}^{\ensuremath{\mp}}V$ vertex ($V=Z or \ensuremath{\gamma}$) does not occur at the tree level, but is generated at one-loop order. We derive explicit formulas for the contribution

In the minimal supersymmetric model (MSSM), the {ital tree}{minus}{ital level} mass of the lightest Higgs scalar {ital h}{sup 0} cannot be larger than the mass of the {ital Z} boson. We have computed the one-loop radiative correction to the upper bou
Two-component spinors are the basic ingredients for describing fermions in quantum field theory in four space-time dimensions. We develop and review the techniques of the two-component spinor formalism and provide a complete set of Feynman rules for

This biennial Review summarizes much of Particle Physics. Using data from previous editions, plus 2205 new measurements from 667 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons. We also

Alternative decay modes of the W and Z bosons may provide a method either to discover the supersymmetric partners of leptons or to set greatly improved limits on their masses. Details are provided on these methods, and various distributions are shown

A recent paper from Perl pointed out that existing limits from ${e}^{+}$${e}^{\mathrm{\ensuremath{-}}}$ annihilation data for a fourth-generation charged lepton ${L}^{+}$ were not valid if the mass splitting between the lepton and its associated neut

We consider a conventional SU(2) @ U(1) gauge theory with two (or more) Higgs doublets, but with the fermion mass scale dctcrmined by the vacuum expectation values of the Higgs particles rather than determined only by widely differing Higgs couplings
