Modelling of Track Reconstruction Inside Jets with the 2016 ATLAS $\sqrt{s}= 13$ TeV pp dataset
Inside the core of high transverse momentum jets, the particle density is so high that the tracks of charged particles begin to overlap, and due to the different charged particles, pixel clusters in the ATLAS inner detector begin to merge. [...]
