Research activities

Trigger activities for CMS Forward Physics: software developments

Contributions to the development of new trigger paths (L1+HLT) for the Forward Physics Group, in particular for the production of exclusive dielectrons, dijets, electron-jet-gap and forward jets with rapidity gaps in between. Work with X. Rouby and J.J. Hollar. These triggers have been integrated in the CMS software before the massive MC production (CSA07).

Photon induced physics at LHC: phenomenology and analysis

(2005-present) Contributions to Louvain photon group activities (UCL CP3) in photon-photon and photon-proton related research. Interests in the production of photon-induced Higgs boson and single top quark. Extraction of the Vtb value of the Cabibbo-Kobayashi-Maskawa matrix element. Participation to the γγ→μμ, γγ→ee approved analysis for the CMS Forward Physics group, with its application to early LHC data observation. Photon-induced Higgs boson and single top quark production is also investigated.

DELPHES, a framework for fast simulation of a general purpose LHC detector: software development

(2005-present) Knowing whether theoretical predictions are visible and measurable in a High Energy experiment is always delicate, due to the complexity of the related detectors, DAQ chain and software. DELPHES, written with Xavier Rouby, provides a framework for fast simulation of a general purpose experiment. The simulation includes tracking, calorimetry and muon system, embedded into a magnetic field, and possible very forward detectors arranged along the beamline. The framework is interfaced to standard file format (e.g. Les Houches Event File) and outputs observable analysis data objects, like missing transverse energy and collections of electrons or jets. The simulation of detector response takes into account the detector resolution, and usual reconstruction algorithms for complex objects, like FastJet[2]. A simplified preselection can also be applied on processed data for trigger emulation. Detection of very forward scattered particles relies on the transport in beamlines with the Hector[3] software.
