The second part of this review is devoted to the Higgs sector of the Minimal Supersymmetric
Standard Model. The properties of the neutral and charged Higgs bosons of the extended …

The breaking of electroweak symmetry, and origin of the associated “weak scale”, v weak=
1/2 2 GF= 175 GeV, may be due to a new strong interaction. Theoretical developments over …

Precision electroweak data presently favors a weakly-coupled Higgs sector as the
mechanism responsible for electroweak symmetry breaking. Low-energy supersymmetry …

Photon-photon collisions are investigated in the framework of the two-component dual
parton model. The model contains contributions from direct, resolved soft, and resolved hard …

Physical principles of colliding γγ and γe beams are described briefly. Beam-beam effects
restricting luminosity are considered. A possible scheme of collision and beam ejection is …

The physics potential of e+ e− linear colliders is summarized in this report. These machines
are planned to operate in the first phase at a center-of-mass energy of 500GeV, before being …

We elaborate on the production of the standard model Higgs particle at high-energy e+ e−
colliders through the reaction e+ e−→ ZH. Particular emphasis is put on the intermediate …

We investigate the possibilities of probing the electroweak scale seesaw scenarios such as
type-I, type-II, and type-III seesaw at e-γ and γ γ colliders. For the case of type-I seesaw, the …

Recent theoretical results have demonstrated that noncommutative geometries naturally
appear within the context of string or M theory. One consequence of this possibility is that …

CP violation in top physics is reviewed. The standard model has negligible effects,
consequently CP violation searches involving the top quark may constitute the best way to …
