Prospects for heavy-flavour measurements with the ALICE inner and forward tracker upgrade

During the second long shutdown (LS2) of the LHC the ALICE detector will be improved with the installation of an upgraded Inner Tracking System (ITS) and a new Muon Forward Tracker (MFT).

Sumario:During the second long shutdown (LS2) of the LHC the ALICE detector will be improved with the installation of an upgraded Inner Tracking System (ITS) and a new Muon Forward Tracker (MFT). These detectors will crucially contribute to the precise characterization of the high-temperature, strongly-interacting medium created in ultra-relativistic Pb-Pb collisions at √s(NN) = 5.5 TeV. In the central barrel, the upgraded ITS will consist of seven cylindrical layers of silicon pixel detectors, starting at a radial distance of 22.4 mm from the beam axis. At forward rapidity, the MFT will be composed of five silicon pixel planes added in the acceptance of the existing Muon Spectrometer (-4 < ƞ < -2.5), upstream to the hadron absorber. Detailed results on the expected performances for heavy-flavour (HF) measurements down to low transverse momentum, with the upgraded ITS and MFT, will be given for central Pb-Pb collisions for various benchmark analyses, assuming an integrated luminosity of 10 nb(-1), as foreseen for the ALICE upgrade programme.
