Towards a new global QCD analysis: low x DIS data from non-linear evolution

Abstract. A new approach to global QCD analysis is developed. The main ingredients are two QCD-based evolution equations. The first one is the Balitsky-Kovchegov non-linear equation, which sums higher twists while preserving unitarity. The second equation is linear and it is responsible for the correct short distance behavior of the theory, namely it includes the DGLAP kernel. Our approach allows for extrapolation of the parton distributions to the very high energies available at the LHC as well as very low photon virtualities,

Remarks on high energy evolution

. All existing low x data on the F2 structure function are reproduced using two fitting parameters, the other parameters were taken as constants. The result is
