Deep inelastic scattering and factorization in the ’t Hooft Model
نویسندگان
چکیده
We study in detail deep inelastic scattering in the ’t Hooft model. We are able to analytically check current conservation and to obtain analytic expressions for the matrix elements with relative precision O(1/Q2) for 1− x ≫ β/Q. This allows us to compute the electron-meson differential cross section and its moments with 1/Q precision. For the former we find maximal violations of quark-hadron duality, as it is expected for a large Nc analysis. For the latter we find violations of the operator product expansion at next-to-leading order in the 1/Q expansion. PACS numbers: 12.38.Aw, 12.39.St, 11.10.Kk, 11.15.Pg

Breakdown of the operator product expansion of deep inelastic scattering in the ’t Hooft model
We consider deep inelastic scattering in the ’t Hooft model. Being solvable, this model allows us to directly compute the moments associated to the cross section at next-to-leading order in the 1/Q expansion. We perform the same computation using the operator product expansion. We find that all the terms match in both computations except for one in the hadronic side, which is proportional to a ...
متن کاملv 1 4 D ec 1 99 5 Small x physics in deep inelastic lepton scattering
The perturbative QCD predictions concerning deep inelastic scattering at low x are summarized. The theoretical framework based on the leading log 1/x resumma-tion and k t factorization theorem is described. The role of studying final states in deep inelastic scattering for revealing the details of the underlying dynamics at low x is emphasised and some dedicated measurements, like deep inelasti...
متن کاملQuantum Chromodynamics and Deep Inelastic Scattering
This article first describes the parton model which was the precursor of the QCD description of hard scattering processes. After the discovery of QCD and asymptotic freedom, the first successful applications were to Deep Inelastic lepton– hadron scattering. The subsequent application of QCD to processes with two initial state hadrons required the understanding and proof of factorization. To tak...
متن کاملQuark Initial State Interaction in Deep Inelastic Scattering and the Drell - Yan process ∗
We pursue a phenomenological study of higher twist effects in high energy processes by taking into account the off-shellness (virtuality) of partons bound in the nucleon. The effect of parton off-shellness in deep inelastic ep → eX scattering (DIS) and the Drell-Yan process (pp → l ¯ lX) is examined. Assuming factorization and a single-parameter Breit-Wigner form for the parton spectral functio...
