Higgs Particles at Future Hadron and Electron–positron Colliders *
The prospects for discovering Higgs particles and studying their fundamental properties at future high–energy electron–positron and hadron colliders are reviewed. Both the Standard Model Higgs boson and the Higgs particles of its minimal supersymmetric extension are discussed. We update various results by taking into account the new value of the top quark mass obtained by the CDF Collaboration ...
متن کاملIndirect Probe of Electroweak-Interacting Particles at Future Lepton Colliders
Various types of electroweak-interacting particles, which have non-trivial charges under the SU(2)L × U(1)Y gauge symmetry, appear in various extensions of the Standard Model. These particles are good targets of future lepton colliders, such as the International Linear Collider (ILC), the Compact LInear Collider (CLIC) and the Future Circular Collider of electrons and positrons (FCC-ee). An adv...
متن کاملEvading Astrophysical Constraints on Axion-Like Particles
Stellar energy loss arguments lead to strong constraints on the coupling φγγ of a light axion-like particle to two photons. Helioscopes, like CAST, are able to put competitive bounds. The PVLAS experiment has recently observed a rotation of the polarization of a laser propagating in a magnetic field that can be interpreted as the effect of a quite strong φγγ coupling. We present scenarios where...
متن کاملObservables at Future Colliders
The discovery of a new neutral gauge boson Z ′ with a mass in the TeV region would allow for determination of gauge couplings of the Z ′ to ordinary quarks and leptons in a model independent way. We show that these couplings in turn would allow us to determine the nature of the extended gauge structure. As a prime example we study the E6 group. In this case two discrete constraints on experimen...
متن کاملStable Massive Particles at Colliders
We review the theoretical motivations and experimental status of searches for stable massive particles (SMPs) which could be sufficiently long-lived as to be directly detected at collider experiments. The discovery of such particles would address a number of important questions in modern physics including the origin and composition of dark matter in the universe and the unification of the funda...
