  RESEARCH INTERESTS
     

Prof. Neu's research program focuses on the building blocks of the Universe and how those building blocks interact. He studies exotic forms of matter produced at the Large Hadron Collider (LHC) at CERN as a collaborator on the Compact Muon Solenoid (CMS) experiment.

His specific interests focus on the characterization of the Higgs boson. The recent discovery of the Higgs boson has solved a significant open question in modern physics: How do the fundamental particles obtain mass? The discovery of the Higgs boson provided direct evidence for the best theory for the origin of mass -- and this advancement won Peter Higgs and Francois Englert the Nobel Prize in Physics in 2013.

However, Higgs-like bosons are predicted in many new theories of the fundamental interactions. Detailed characterization of the Higgs boson we are producing at the LHC and observing with the CMS experiment is essential for putting this new particle in context: Does this Higgs boson fit well with our current understanding of the dynamics of the fundamental world -- or is it an indicator of some new, never-before-seen interactions?  Such "new physics" would shape the way we understand our Universe in the years to come.

Prof. Neu is also interested in searches for yet-unseen fundamental particles -- the existence of which could help answer some other big questions in modern science: What is dark matter? Are there any new forces beyond the ones we are familiar with? Why is gravity so weak? Why is there so much more normal matter in our Universe rather than anti-matter?  Prof. Neu's research pursues these exciting questions and more.

On CMS, Prof. Neu contributes to the operation of the electromagnetic calorimeter (ECAL), a device made of thousands of PbWO4 crystals that makes very precise measurements of the energy and flight direction of photons and electrons produced in the collisions provided by the LHC.  He is also participating in several R&D projects for the future upgrade of the CMS experiment, including new low-noise electronics and advanced solid-state radiation tolerant photodetectors.

Group members get the opportunity to spend time resident at the CMS experiment at CERN, contributing to the operations of the ECAL, upgrade R&D projects and their individual research pursuits.
