  • About

    Professor Chapman's research specialty is Experimental High Energy Physics. In recent years, research results in this field have led to increased confidence in the Standard Model of weak, electromagnetic, and strong interactions. Currently, the experimental challenges are split between further refinements of the parameters of the model and searchers for phenomenon not described by the model.

    Professor Chapman participated in the study of anti-proton proton interactions in the CDF detector at Fermilab during Run II of that experiment.

    At CDF, the University of Michigan group focused on ElectroWeak and heavy flavor physics with students preparing thesis on W and Z boson measurements and on top quark cross sections and mass measurements.

    U-M Physics is a major contributor to the ATLAS Experiment at the LHC both for the preparation of drift chambers (called the Monitored Drift Tubes or MDT) of the endcap muon detector and for the electronics instrumentation that processes data from all MDT chambers.

    The U-M group has focused on ElectroWeak, Higgs, and Lambda-b physics in the ATLAS experiment. Michigan graduate students are currently working on ATLAS data or have already received their PhD on past ATLAS work.
