Comment on Quarks and Gluons at small x and the SDIS Factorization Scheme ∗

چکیده

I present some comments on the partonic interpretation of the HERA data on the proton structure function. The effects of the resummation of the leading and next-to-leading lnx-contributions are discussed. A new factorization scheme, in which these resummation effects are absorbed into a steep redefinition of the gluon density, is introduced and its (possible) interpretation and phenomenological relevance are suggested.

QCD factorization with heavy quarks

Recent improvements [1] of the next-to-leading log x (NLx) results [2] in the BFKL framework, have stabilized the small-x behaviour in QCD, so that a phenomenological analysis of deep inelastic processes (DIS) seems now possible. However, both the gluon density (satisfying the improved equation) and the impact factors are needed in order to use k-factorization [3] to compute DIS or double DIS p...

Sea Quark or Anomalous Gluon Interpretation for g p 1(x)?

Contrary to what has been often claimed in the literature, we clarify that the hard photongluon cross section ∆σ hard(x) in polarized deep inelastic scattering calculated in the gauge-invariant factorization scheme does not involve any soft contributions and hence it is genuinely hard. We show that the polarized proton structure function g 1(x) up to the next-to-leading order of αs is independe...

On sabbatical leave of absence from Dipartimento di Fisica, Università di Firenze, and INFN,

I investigate, at leading twist level, the consistency of the BFKL equation with the renormalization group, when next-to-leading log-x terms are included in the quark-sea channel of the anomalous dimension matrix. By use of k⊥-factorization, I find that, besides next-to-leading small x resummation formulae, a leading, x-dependent redefinition of initial quarks and gluons is needed. Its interpre...

High-Energy Factorization and Small-x Deep Inelastic Scattering Beyond Leading Order∗

High-energy factorization in QCD is investigated beyond leading order and its relationship to the factorization theorem of mass singularities is established to any collinear accuracy. Flavour non-singlet observables are shown to be regular at small x order by order in perturbation theory. In the singlet sector, we derive the relevant master equations for the space-like evolution of gluons and q...

A Modified Digital Image Watermarking Scheme Based on Nonnegative Matrix Factorization

This paper presents a modified digital image watermarking method based on nonnegative matrix factorization. Firstly, host image is factorized to the product of three nonnegative matrices. Then, the centric matrix is transferred to discrete cosine transform domain. Watermark is embedded in low frequency band of this matrix and next, the reverse of the transform is computed. Finally, watermarked ...
