===================================================== A measurement is presented of the energy flow in the forward region (3.15 < |eta| < 4.9, where h denotes the pseudorapidity) of the CMS detector at the LHC for centreof- mass energies sqrt(s) of 900 GeV, 2360 GeV and 7000 GeV. The energy flow is measured in two different event classes: in minimum bias events and in events with a hard scale provided by a dijet system at central pseudorapidities (|eta| < 2.5) and with transverse energy ET,jet > 8 GeV at sqrt(s) of 900 GeV and 2360 GeV and with ET,jet > 20 GeV at sqrt(s) of 7000 GeV. The measured forward energy flow is found to be significantly different between the two event classes. The result of the forward energy flow measurement for the two event classes is compared to predictions from Monte Carlo event generators that were tuned to describe the charged particle spectra seen at central rapidities. We present studies of forward jets reconstruction using the inclusive events from proton-proton collisions at sqrt(s)= 7 TeV in CMS. The jets are reconstructed with the anti-kT (R = 0.5) algorithm in the Hadronic Forward (HF) calorimeter in range 3.2 <|eta|< 4.7. ===================================================== TOPLANTIYA AIT DOKUMANLAR SEMINERDEN SONRA BU SAYFADAN ELDE EDILEBILIR.
