Energy Dependence of the Pomeron Spin-Flip
There is no theoretical reason to think that the spin-flip component of the Pomeron is zero. One can measure the spin-flip part using Coulomb-nuclear interference (CNI). Perturbative QCD calculations show that the spin-flip component is sensitive to the smallest quark separation in the proton, while the non-flip part probes the largest separation. According to HERA results on the proton structu...
متن کاملHigh Energy Evolution with Pomeron Loops
The high energy/density QCD has been widely used for DIS phenomenology with a projectile particle considered as perturbative and dilute. We review some recent attempts to derive a high energy evolution kernel which treats targets and projectiles in a symmetric manner. From theoretical point of view the problem is tightly related to inclusion of Pomeron loops in the evolution. The ultimate goal ...
متن کاملPomeron Loops in High Energy Qcd
Over the last three decades, one of the main active fields of research within QCD has been the study of its behavior in the high energy limit. In general, a scattering process will be considered as a high energy one, when the (square of the) total energy s of the colliding (hadronic) objects is much larger than the momentum transfer Q2 between them. At the same time one hopes to approach the pr...
متن کاملENERGY CONSERVATION and POMERON LOOPS in HIGH ENERGY EVOLUTION
A convenient approach to small-x evolution in QCD is the dipole picture which was formulated by Mueller a decade ago [1–3]. Mueller’s formalism leads to the BFKL equation but it also goes beyond the BFKL formalism, since here it is possible to take into account unitarisation effects due to multiple scatterings (multiple pomeron exchanges). In Mueller’s model dipoles in the same cascade (wavefun...
