A combination is presented of all inclusive deep inelastic cross sections previously published by the H1 and ZEUS collaborations at HERA for neutral and charged current e+-p scatering for zero beam polarisation. The data were taken at proton beam energies of 920, 820, 575 and 460 GeV. The combined cross sections were input to QCD analyses at leading order, next-to-leading and at next-to-next-to-leading order, providing a new set of parton distribution functions. The analysis was extended by including HERA data on charm and jet production. Variants of pdf fuctions HERAPDF2.0, HERAPDF2.0AG, HERAPDF2.0FF, HERAPDF2.0Jets are presented. New measurent of the strong coupling constant αs(MZ2) and xF3γZ are also presented.
