Fit on world data of inclusive proton DIS cross-sections — •Dominik Gabbert² and Lara De Nardo^1,3 — ¹DESY, 22603 Hamburg, Germany — ²DESY, 15738 Zeuthen, Germany — ³TRIUMF, Vancouver, British Columbia V6T 2A3, Canada

Inclusive proton DIS cross-sections have been measured precisely on a large kinematic region by both collider and fixed target experiments. However, a fit of the structure function F₂ which is self-consistent with respect to the knowledge of R=σ_L/σ_R is not available. A fit is presented which fulfills this requirement based on a phenomenological parameterization first used by ALLM including newer data available. Furthermore, an accurate method to consider normalization uncertainties is applied and detailed information is provided about parameter and fit uncertainties.
