Query: Novel strategies at LHCb for particle identification   The LHCb experiment at the Large Hadron Collider (LHC) is performing high
precision measurements in the flavour sector. An excellent performance of the
particle identification (PID) detectors as well as the development of new data
taking techniques are of fundamental importance in order to cope with
increasingly harder challenges posed by the LHC Run 2. The approach of
data-driven calibration of particle identification performance at LHCb has
changed significantly from Run 1 to Run 2 and calibration samples are now
selected directly in the LHCb high-level trigger. This change of data-taking
paradigm enables larger calibration samples with respect to Run 1 to be
collected, giving access to low-level detector informations useful for studies
of systematic effects, while retaining the same (or improving) the PID
performances observed Run 1.
