 Production, spectroscopy and properties of heavy hadrons / Galanti, Mario (Rochester U.) /ALICE,ATLAS,CMS and LHCB Collaborations In this report I will describe the latest results of the ALICE, ATLAS, CMS, and LHCb experiments in the fields of production, spectroscopy, and properties of heavy hadrons. In particular, I will concentrate on measurements of quarkonium production cross sections, polarization, and mass, on measurements of production cross sections and lifetimes of open heavy flavors, on the recent observations of new states and decay modes, and on other searches for new and exotic hadrons..

 Hadronic Tau reconstruction and identification performance in ATLAS and CMS / Galloni, Camilla (Zurich U.) /ATLAS and CMS Collaborations The reconstruction and identification of hadronic tau lepton decays is an essential requisite of the ATLAS and CMS physics program, for what concerns both the standard model measurements and searches of new physics beyond the standard model. In the following, the ATLAS and CMS algorithms for the hadronic tau lepton decays reconstruction and identification are presented, together with the measurements of the most important performance figures and calibrations..
