New Phenomena beyond Both the Standard Model and Mssm 1 2 Extended Gauge Sectors
Signals for new, non-supersymmetric physics at hadron colliders are reviewed. We focus on extended gauge sectors and new matter particles. OVERVIEW The Standard Model (SM) is in complete agreement with present experimental data. Nevertheless, it is believed to leave many questions unanswered, and this belief has resulted in numerous attempts to nd a more fundamental underlying theory. One key i...
متن کاملExtended Higgs Sectors
I give a brief overview of the motivations for and experimental probes of extended Higgs sectors containing more than the single Higgs doublet field of the Standard
متن کاملExtended Gauge Sectors
Present and future prospects for the discovery of new gauge bosons, Z ′ and W , are reviewed. Particular attention is paid to hadron and ee collider searches for the W ′ of the Left-Right Symmetric Model.
متن کاملCERN LHC phenomenology of an extended standard model with a real scalar singlet
Gauge singlet extensions of the standard model (SM) scalar sector may help remedy its theoretical and phenomenological shortcomings while solving outstanding problems in cosmology. Depending on the symmetries of the scalar potential, such extensions may provide a viable candidate for the observed relic density of cold dark matter or a strong first order electroweak phase transition needed for e...
متن کاملCollider Signatures of Singlet Extended Higgs Sectors
We explore the collider signatures of the Higgs sectors in singlet-extended MSSM models. We find that even with reduced couplings due to singlet mixing, a significant portion of the parameter spaces have a discoverable Higgs via traditional decay modes or via invisible decays (directly to neutralinos or through cascade decays to neutralinos and neutrinos). For illustrative points in parameter s...
