It will allow the study of the process of thermalization of heavy quarks in the medium by measuring heavy flavour charmed and beauty baryons and extending these measurements down to very low pT for the first time. It will also give a better understanding of the quark mass dependence of in-medium energy loss and offer a unique capability of measuring the beauty quarks while also improving the beauty decay vertex reconstruction. Finally, the upgraded ITS will give us the chance to characterize the thermal radiation coming from the QGP and the in-medium modification of hadronic spectral functions as related to chiral symmetry restoration.
