Description

The 13th International Workshop on Top Quark Physics (TOP 2020) will bring together experimentalists and theorists to present and discuss the latest developments in top-quark physics. This year's meeting will be an on-line conference with support provided by IPPP Durham. The programme includes a mini-workshop entitled "Jets in top physics: substructure, tagging and machine learning".

Young scientists are especially encouraged to participate, and there will be a poster session as well as a block of short plenary talks in the "Young Scientist Forum'', allowing them to present their work.

Please note that all times correspond to CERN time. Presenters with standard 30 minute talks should speak for 25 minutes or less, leaving at least 5 minutes for questions.

The conference will be held on Zoom; information about how to join, and detailed instructions for participants, speakers, and session chairs is in the "Zoom Instructions" menu link.

    Top mass shift from recalibration of flavor-dependent jet energy corrections in the D0 lepton+jets top mass measurement 1h
    
    Abstract:
    We investigate a possible explanation for the 2.4 GeV (2.7 sigma) difference in the top quark mass as measured by D0 and CMS, ATLAS and CDF. Our earlier investigation of the flavor-dependent Jet Energy Scale (flavor-JES) calibration suggested that the flavor-JES used by D0 for Run IIb may have converged to a non-global, unphysical minimum. The
    study was based on internal documents released into the public domain after a 5-year moratorium. Furthermore, Run IIb makes up a majority of the full Run II dataset. In addition, the flavor-JES was found to be very sensitive to the parton shower model in Pythia 6 versus Herwig7, only former of which was used in the original flavor-JES study.
    
    In this work we propagate the difference between the re-derived and the original flavor-JES into the top quark mass in the lepton+jet channel. This is done utilising publicly available information and published papers. We find that the flavor-JES is enough to fully explain the observed mass shift, with the Pythia6 and Herwig7 results differing by 1.32 GeV. A crude average of the shifts given by the two generators
    results into a re-interpreted mass of 172.50 GeV. As a caveat, this work has been performed entirely outside of D0 collaboration, and only utilising documents (both published and internal) released to the public domain.
