New Structure Function Results at Low x and High Q^2 from HERA

Abstract

A precise proton structure function F_2 at low x is measured. The data is interpreted in the framework of QCD with an extraction of gluon density xg. The charm contribution to F_2 is determined in an extended kinematic range. Neutral and charged current cross-sections at high Q^2 are also measured and compared with the Standard Model predictions.
