Search for Light NMSSM Higgs Boson Production in bb Final States with the CMS experiment — •Gregor Hellwig1, Rainer Mankel1, Alexei Raspereza1, Christian Sander2, Daniel Tröndle2, and Roberval Walsh1 — 1Deutsches Elektronen-Synchrotron — 2Universität Hamburg
On July 4th, 2012 the discovery of a Higgs boson compatible with the Higgs boson of the Standard Model of Particle Physics was announced. However, the precise structure of the Higgs sector still needs to be investigated. A very important question is whether additional Higgs bosons exist, as they are predicted e.g. by various extensions of the Standard Model.
In the Next-to-Minimal Supersymmetric Standard Model (NMSSM), scenarios are possible in which one of the Higgs bosons has a mass below that of the Z boson. Due to reduced couplings to the electroweak gauge bosons, such a particle may have evaded the previous searches at the LEP collider.
This work presents the status of a search for such light NMSSM Higgs bosons decaying in the bb channel with the CMS experiment at the LHC. This presentation discusses the elements of the analysis, including the data-driven background estimation, the extraction of the signal, and the interpretation within the NMSSM framework.
