A new calibration method for charm jet identification validated with proton-proton collision events at $\sqrt{s}$ = 13 TeV

Understand

Many measurements at the LHC require efficient identification of heavy-flavour jets, i.e.

• jets originating from bottom (b) or charm (c) quarks.
• An overview of the algorithms used to identify c jets is described and a novel method to calibrate them is presented.
• This new method adjusts the entire distributions of the outputs obtained when the algorithms are applied to jets of different flavours.
