QCD coherence in deep inelastic scattering at small x

QCD coherence effects in initial state radiation at small x in deep inelastic scattering in HERA kinematics are studied with the help of the Monte Carlo model SMALLX. Theoretical assumptions based on the CCFM evolution equation are reviewed and the basic properties of the partonic final states are investigated. The results are compared with those obtained in the conventional DGLAP evolution sch...

ASSESSING QCD IN DEEP-INELASTIC ey SCATTERING

We consider hadron production in deep inelastic scattering of electrons on photons. (i) Exploiting the leading order QCD corrections due to gluon bremsstrahlung we find that the photon structure functions rapidly approach their asymptotic form which can be calculated in QCD. (ii) Replacing QCD by a theory with fixed quark-gluon coupling constant [scalar or Abelian gluonsl gives dramatic changes...

Forward π◦-Meson and Charged Particle Production in Deep Inelastic Scattering at low Bjorken-x

High transverse momentum π-mesons and charged particles are measured in deep inelastic e-p scattering events at low Bjorken-x taken with the H1 detector at HERA. The production of high pt particles is strongly correlated to the emission of hard partons in QCD and is therefore sensitive to the dynamics of the strong interaction. For the first time the measurement of single particles has been ext...

Deep Inelastic Scattering at HERA

Inclusive production of D(2010) mesons in deep inelastic scattering has been measured using ep and ep data obtained with the ZEUS detector at HERA using integrated luminosities of 16.7 and 65.2pb, respectively. The decay channel D → Dπ with D → Kπ and corresponding antiparticle decays were used to identify D mesons. The D cross sections in ep and ep interactions agree with NLO QCD predictions, ...

Non-factorizable contributions to deep inelastic scattering at large x

We use soft-collinear effective theory (SCET) to study the factorization properties of deep inelastic scattering in the region of phase space where (1− x) ∼ ΛQCD/Q. By applying a regions analysis to loop diagrams in the Breit frame, we show that the appropriate version of SCET includes anti-hard-collinear, collinear, and softcollinear fields. We find that the effects of the soft-collinear field...
