Structure function and angular ordering at small x

Abstract: We compute the gluon distribution in deep inelastic scattering at small x by solving numerically the angular ordering evolution equation. The leading order contribution, obtained by neglecting angular ordering, satisfies the BFKL equation. Our aim is the analysis of the subleading corrections. Although not completethe exact next-to-leading contribution is not yet available -these corrections are important since they come from the physical property of coherence of QCD radiation. In particular we discuss the sub… Show more

“…In order to quantify effects of coherence, running couplig effects and hard scale dependence we take into account only hard emissions [13,[18][19][20][21][22][23] and compare the solution to solution of the BK equation which is hard scale independent and where the running coupling effects are well understood. Working with this approximation we can make easier comparison of our results for saturation scale with those obtained in [23].…”
