Measurements of $b$-jet moments sensitive to $b$-quark fragmentation in $t \bar{t}$ events at the LHC with the ATLAS detector
The measurement of several observables sensitive to the fragmentation of $b$-quarks with 36 fb${}^{-1}$ of $\sqrt s = 13$ TeV LHC data are presented. Jets containing $b$-hadrons are obtained from a sample of dileptonic $t \bar{t}$ events, and the associated set of charged-particle tracks is separate...
