| Abstract | Neutral Current e+-p -> e+-X single differential cross sections
ds/dQ2 are presented using the full HERA dataset recorded with the
H1 detector.
The cross sections are measured in the region
of large negative four-momentum transfer squared Q2 >=200 GeV^2 and inelasticity y<0.9.
The total integrated luminosity amounts to 270 pb^{-1} of
e^+p and 165 pb^{-1} of e^-p data.
The measurements are compared to predictions of the
Standard Model.
A form factor analysis is
performed and an upper limit is obtained
on the quark radius of 0.74*10^{-18} m at $95\%$ CL. |
