Query: Low pT Hadronic Physics with CMS   The pixel detector of CMS can be used to reconstruct very low pT charged
particles down to about 0.1 GeV/c. This can be achieved with high efficiency,
good resolution and a negligible fake rate for elementary collisions. In the
case of central PbPb collisions the fake rate can be kept low for pT > 0.4
GeV/c. In addition, the detector can be employed for identification of neutral
hadrons (V0s) and converted photons.
