Journal ArticleDOI
TL;DR: In this article, the main body of predictions of the theory for deep-inleastic scattering on either unpolarized or polarized targets is re-obtained by a method which only makes use of the simplest tree diagrams and is entirely phrased in parton language with no reference to the conventional operator formalism.

Journal ArticleDOI
TL;DR: In this article, a review of the physics of two-photon particle production and its applications is presented, where the authors discuss what information on the γγ → h transition can be extracted from the related experiments and how it can be done.

Journal ArticleDOI
TL;DR: In this article, the authors determined the refractive indices for photon propagation, and the absorption coefficient and polarization selection rules for photon splitting, in a strong constant magnetic field, both in the effective Lagrangian (low frequency) approximation and in more accurate approximation which exactly sums the vacuum polarization ring diagrams, neglecting only internal virtual photon radiative corrections.

TL;DR: In this paper, a global parton analysis of deep inelastic and related hard-scattering data was performed, including the parton evolution of u and d type quarks.
Abstract: We perform a global parton analysis of deep inelastic and related hard-scattering data, including ${{\mathcal{O}}}(\alpha_{\rm QED})$ corrections to the parton evolution. Although the quality of the fit is essentially unchanged, there are two important physical consequences. First, the different DGLAP evolution of u and d type quarks introduces isospin violation, i.e. $u^p eq d^n$ , which is found to be unambiguously in the direction to reduce the NuTeV $\sin^2\theta_W$ anomaly. A second consequence is the appearance of photon parton distributions $\gamma(x,Q^2)$ of the proton and the neutron. In principle these can be measured at HERA via the deep inelastic scattering processes $e N \to e\gamma X$ ; our predictions are in agreement with the present data.

Journal ArticleDOI
TL;DR: In this article, the deep inelastic structure functions of the photon in an asymptotically free gauge theory were considered, and it was shown that the short distance analysis determined the shape and magnitude and not merely the Q 2 dependence of the structure functions.
