        In appreciation of Fred James 15m

        Bob Cousins retired from UCLA but is still active in the CMS Collaboration, of which he was Deputy Spokesperson in 2007-2009. He has had a special interest in statistical issues for HEP and was fortunate to have a long friendship with Fred James.

        Speaker: Robert Cousins Jr (University of California Los Angeles (US))
      • 16:15 → 16:30
        Personal Memories 15m

        Member of audience can provide a short (< 90 sec) personal memory of Fred. A document is provided (link below) to collect all these memories

        Parameter determination in HEP: from MINUIT to auto-differentiation through the Higgs discovery and beyond 1h

        Josh Bendavid is a Research Physicist at CERN. He has worked on CMS since 2007, from the Higgs → γγ search that contributed to the 2012 discovery, for which he earned his PhD from MIT in 2013, to precision electroweak measurements. He has been a CERN fellow, a postdoctoral researcher at Caltech, and a Research Scientist at MIT. Josh was a principal contributor to the CMS W boson mass measurement, in particular the ultra-high-precision muon track reconstruction and calibration, as well as the TensorFlow-based likelihood fits, which use automatic differentiation to handle thousands of nuisance parameters.
