Search for Higgs boson(s) in CMS at the LHC in the llbb topology
Agni Bethani, Jérôme de Favereau, Christophe Delaere, Vincent Lemaitre
Search for Higgs boson(s) within the Standard Model and beyond and also withing a minimal extension of the scalar sector (2HDM).
The final state under study is a Z decaying into a lepton pair associated with two b-jets. This topology is sensitive to a light SM Higgs via the associate ZH production, as well as a middle mass range SM Higgs boson via the inclusive Higgs production followed by its decay into ZZ with one Z decaying into a lepton pair and the other into bbar.
It is also very sensitive to the production of a non standard heavy Higgs boson decaying into Z plus A (pseudo scalar Higgs boson).
Similar selection (but outside of the Z window) is also sensitive to H->aa->llbb, with "a" a generic light scalar.

Study and optimization of b-tagging performances in CMS
Agni Bethani, Christophe Delaere
We are involved in the activities of the btag POG (performance object group) of CMS, in release and data validation and purity measurement. We are also interested in btagging in special cases like for colinear b-jets. Furthermore, we are involved in the re-optimization and improvement of the Combined Secondary Vertex (CSV) tagger for the 2012 analyses.
External collaborators: Strasbourg CMS group, CMS collaboration.
