| Abstract |
A precise measurement is presented of the inclusive ep scattering cross
section in the kinematic region of low Bjorken x and four-momentum
transfer squared 0.35 \le Q2 \le 12 GeV2. The data were
recorded with the H1 detector at HERA in 1999/2000, with a proton beam
energy of 920 GeV and a positron beam energy of 27.6 GeV.
For part of the data the interaction vertex was shifted by +70~cm,
thereby accessing a region of lower Q2 than for the nominal vertex
position. The cross-section measurement is used to determine the proton
structure function F2(x,Q2) and the longitudinal structure function
FL(x,Q2). |
