چکیده
The measurement and QCD analysis of neutral and charged current cross sections at HERA are presented. For the kinematic range of four-momentum transfer Q 2 between ≈ 1 GeV 2 and 30000 GeV 2 and Bjorken x between 0.0013 and 0.65 the data are compared to NLO QCD predictions. In dedicated NLO QCD analyses the extraction of the parton distribution functions of the proton is performed. Results for the measurement of the strong coupling constant αs are presented.

متن کاملMeasurements of the proton structure at HERA and their impact for LHC
Recent results on proton structure functions from H1 and ZEUS Collaborations are presented. The data have been recorded in ep and e−p collisions for both Neutral Current and Charged Current reactions, covering a wide kinematic range of squared four-momentum transfers Q2, from 0.2GeV2 to 30000GeV2, and Bjorken x between ∼5 ∗ 10−6 and 0.65. Data from both experiments have been combined, leading t...

A brief overview is given on the physics and future lepton-nucleon collider facilities to explore the domain of high parton densities at low Bjorken x, with HERA, the electron-ion collider (EIC) and with THERA-in ep, polarised − → e − → N and eA mode. The only existing lepton-nucleon collider which accesses the region of low Bjorken x is HERA. During 2001 the detectors were upgraded and the mac...

متن کاملParton distributions : a study of the new HERA data , α s , the gluon and pp̄ jet production
New data, especially HERA measurements of the proton structure function at small x, allow the opportunity to improve our knowledge of the gluon and quark distribution functions. We perform a global analysis which incorporates these new precise data, and which extends down to Q2 = 1.5 GeV. We discuss the sensitivity to the value of αs and the improvement in the determination of the gluon. We com...
