BFKL signatures at a linear collider
Abstract
The BFKL dynamics can be successfully tested at the future high energy e+e- linear collider. The total γ*γ* cross-section is calculated in the Leading Log QCD dipole picture of BFKL dynamics, and compared with the one from 2-gluon exchange. The rapidity dependence of the cross-section remains a powerful tool to increase the ratio between the BFKL and the 2-gluon cross-sections and is more sensitive to BFKL effects, even in the presence of higher order corrections. Other potential signals like diffractive J/ and 'forward' jet productions will also be discussed.
