Description
The ALICE detector allows precise measurements of the transverse energy in p+p and Pb-Pb collisions at LHC energies. We will discuss studies of the transverse energy in p+p collisions at sqrt{s} = 0.9, 2.76, and 7 TeV and in Pb-Pb collisions at sqrt{s_{NN}} = 2.76 TeV.
The ALICE Inner Tracking System (ITS) and the Time Projection Chamber (TPC) are used for precise measurements of the transverse energy of charged hadrons and the electromagnetic calorimeters (PHOS and EMCal) are used for measurements of the transverse energy for electrons, photons, and neutral hadrons which dominantly decay through Dalitz decays.
The detector performance will be presented and the measurement technique described in detail.
Particular focus will be placed on the hadronic E_T and EMCal measurements, and also on studies with Monte Carlo simulations and assignment of systematic errors for the analyses.
