Recently, an exact conformal mapping between soft gluons emitted from jets at large angle in e+e−-annihilation and those in the BFKL evolution of a high energy hadron has been proposed. We elucidate some remarkable aspects of this correspondence and use them to analytically compute the distribution and correlation of gluons in the interjet region. We also establish the timelike counterpart of Mueller's dipole model and discuss the resulting linear and nonlinear evolution equations.

Using the AdS/CFT correspondence, we calculate the polarized structure functions in strongly coupled Script N = 4 supersymmetric Yang-Mills theory deformed in the infrared. We find that the flavor singlet contribution to the g1 structure function is vanishingly small, while the flavor non-singlet contribution shows the Regge behavior at small–x with an intercept slightly less than 1. We explicitly check that the latter satisfies the moment sum rule. We discuss the `spin crisis' problem and suggest that at strong coupling the spin of a hadron entirely comes from the orbital angular momentum.

Based on the AdS/CFT correspondence, we present a holographic description of various C-odd exchanges in high energy baryon-(anti)baryon scattering, and calculate their respective contributions to the difference in the total cross sections. We show that, due to the warp factor of AdS 5, the single Odderon exchange gives a larger total cross section in baryon-baryon collisions than in baryon-antibaryon collisions at asymptotically high energies.
