We describe the phenomenology of light singlet Higgs bosons in the Next-to-Minimal Supersymmetry Model (NMSSM) which are mostly decoupled from the rest of Supersymmetry. Noting that the Large Hadron Collider has not excluded this scenario, we describe previous searches for light Higgs bosons at the Large Electron Positron collider and evaluate the sensitivity to neutralino production and decay to light singlet Higgs bosons at the proposed [Formula: see text] GeV Circular Electron Positron Collider.

Integrated Luminosity

Recent results from the four experiments ALEPH, DELPHI, L3 and OPAL at the large electron-positron collider, LEP, at CERN are reviewed. Analyzes from an integrated luminosity of about 20 pb −1 per experiment, taken at different center-of-mass energies within ±3 GeV around the Z0 resonance, are available now. Here, the main emphasis is put on the relevance of these measurements for precision tests of the Standard Model of the electroweak interaction.

Large Electron Positron

Particle physics theory has reached a stage where experimental confirmation of some of the predictions is needed before further progress can be made towards the grand unification of the major forces in nature. This is one of the main aims of the Large Electron–Positron Colliding-Beam Facility (LEP), the construction of which was approved last year by the twelve Member States of CERN. The reasons for the choice of such a facility are explained, and the difficulties of driving a ring tunnel, 27 km in circumference, under the countryside surrounding the present CERN site, are described. The design of the collider and its components is discussed, involving some new techniques to minimize the cost of the facility, which has to be funded out of a constant CERN budget. Finally, some of the methods of carrying out the experiments are explained, and information on the progress to date is given.

Large Electron Positron

The 40 years old Standard Model, the theory of particle physics, seems to describe all experimental data very well. All of its elementary particles were identified and studied apart from the Higgs boson until 2012. For decades, many experiments were built and operated searching for it, and finally, the two main experiments of the Large Hadron Collider (LHC) at CERN, CMS and ATLAS, in 2012 observed a new particle with properties close to those predicted for the Higgs boson. In this paper, we outline the search story: the exclusion of the Higgs boson at the Large Electron Positron (LEP) collider, and its observation at LHC.
