Tunneling transition to the Pomeron regime 1
نویسندگان
چکیده
We point out that, in some models of small-x hard processes, the transition to the Pomeron regime occurs through a sudden tunneling effect, rather than a slow diffusion process. We explain the basis for such a feature and we illustrate it for the BFKL equation with running coupling by gluon rapidity versus scale correlation plots.

Running coupling and BFKL pomeron
PACS numbers: 12.38 Cy One of the major issues in the high energy limit of QCD is the problem of interplay between the perturbative and non-perturbative regimes. The BFKL Pomeron in the leading logarithmic approximation [1] results in the equation which exhibits the characteristic diffusion pattern [2]. In the process with two, comparable hard scales (for example γ−γ, or forward jet/π0 in DIS) ...
متن کاملSpatial Compactification and Decay-Rate Behaviour
The transition from instanton-dominated quantum tunneling regime to sphaleron-dominated classical crossover regime is explored in (1+1)dimensional scalar field theory when spatial coordinate is compactified. It is shown that the type of sphaleron transition is critically dependent on the circumference of the spatial coordinate.

A comprehensive study of Schottky barrier MOSFET (SBMOSFET) scaling issue is performed to determine the role of wafer orientation and structural parameters on the performance of this device within Non-equilibrium Green's Function formalism. Quantum confinement increases the effective Schottky barrier height (SBH). (100) orientation provides lower effective Schottky barrier height in compa...

In this paper, to understand the concept of coupling, molecule density of states that coupled to the metal electrodes will be explained then, based on this concept, a weak and strong coupling for the molecules attached to the metal electrodes will be described. Capacitance model is used to explore the connection of addition energy with the Electron affinity and the ionization energy of the mole...
متن کاملExclusive Diffractive Final States in Electron-proton Collisions
The diffractive scattering is a process where the colliding particles scatter at very small angles and without any color flux in the final state. This involves a propagator carrying the vacuum quantum numbers, called Pomeron and described, in the soft regime, within the Regge theory. The discovery of a big amount of diffractive events in DIS regime provided a hard scale which can be varied over...
