Quark - Antiquark Exchange in γ ∗ γ ∗ Scattering
We calculate the high energy behavior of quark-antiquark exchange in γ * γ * elastic scattering by summing, to all orders, the leading double logarithmic contributions of the QCD ladder diagrams. Motivation comes from the LEP data for σ γ * γ * tot which indicate the need for secondary reggeon exchange. We show that, for large photon virtualities, this exchange is calculable in pQCD. This appli...
متن کاملHigh-energy quark-antiquark elastic scattering with mesonic exchange.
We studied the high energy elastic scattering of quark anti-quark with an exchange of a mesonic state in the t channel with −t/Λ 2 ≫ 1. Both the normalization factor and the Regge trajectory can be calculated in PQCD in cases of fixed (non-running) and running coupling constant. The dependence of the Regge trajectory on the coupling constant is highly non-linear and the trajectory is of order o...
متن کاملQCD Saturation and γ∗-γ∗ Scattering
Two photon collisions at high energy have an important theoretical advantage: the simplicity of the initial state, which gives us a unique opportunity to calculate these processes for large virtualities of both photons in perturbative QCD approach. In this paper we study QCD saturation in two photon collisions in the framework of the Glauber-Mueller approach. The Glauber-Mueller formula is deri...
متن کاملForward Elastic Scattering of Light on Light , γ + γ → γ + γ
The forward elastic scattering of light on light, i.e., the reaction γ + γ → γ + γ in the forward direction, is analyzed utilizing real analytic amplitudes. We calculate ργγ , the ratio of the real to the imaginary portion of the forward scattering amplitude, by fitting the total γγ cross section data in the high energy region 5 GeV ≤ √ s ≤ 130 GeV, assuming a cross section that rises asymptoti...
متن کاملγ-γ Scattering: Saturation and Unitarization in the BFKL Approach
In this paper γ∗ − γ∗ scattering with large, but more or less equal virtualities of two photons is discussed using BFKL dynamics, emphasizing the large impact parameter behavior (bt) of the dipole-dipole amplitude. It is shown that the non-perturbative contribution is essential to fulfill the unitarity constraints in the region of bt > 1/2mπ , where mπ is pion mass. The saturation and the unita...
