Large Impact Parameter

The electromagnetic stopping of intense and relativistic electron beams (REB) arising from femtosecond lasers interacting with a precompressed deuterium–tritium (DT) fuel is investigated within the Bohr–Fermi formalism with a large impact parameter. Dynamical intrabeam correlations in the target are shown to be quantitatively significant for various arrangements of projectile electrons and the overall REB penetration in the DT fuel.

The Impact

A global analysis of the latest diffractive deep inelastic scattering (DIS) data with gluon number fluctuations and impact parameter is performed. The impact parameter is introduced into the scattering amplitude by saturation scale with a Gaussian b-dependence. The results show that the description of the diffractive DIS data is improved once the gluon number fluctuations and impact parameter are included, with [Formula: see text]/d.o.f = 0.878, [Formula: see text]/d.o.f = 0.928 and [Formula: see text]/d.o.f = 0.897 in different sets of free parameters. Moreover, we find that the impact parameter ([Formula: see text] 0.1) is possibly compressed by the gluon number fluctuations, which leads to the value of saturation exponent returning to [Formula: see text] 0.2. This outcome is compatible with the prediction that the saturation exponent is dominated by the fluctuations at sufficiently high energy, which may indicate the possibility of gluon number fluctuations in diffractive DIS data.

We discuss the scattering of two light particles in a D-brane background. It is known that, if one light particle strikes the D-brane at small impact parameter, quantum recoil effects induce entanglement entropy in both the excited D-brane and the scattered particle. In this letter we compute the asymptotic "out" state of a second light particle scattering off the D-brane at large impact parameter, showing that it also becomes mixed as a consequence of quantum D-brane recoil effects. We interpret this as a non-factorizing contribution to the superscattering operator $ for the two light particles in a Liouville D-brane background, that appears when quantum D-brane excitations are taken into account.

Structural Aspects

In these proceedings a stochastic particle (1+1)-dimensional model which mimics high energy evolution and scattering in QCD at fixed impact parameter is presented. The model exhibits a saturation mechanism similar to gluon saturation in QCD as well as all the qualitative features expected in QCD at fixed impact parameter, concerning both the mean-field aspects and the effects of fluctuations, and appears to be in the universality class of the reaction-diffusion process, as also expected for QCD. The evolution equations for the scattering amplitude generated by this model appear as a natural generalization of the Balitsky-JIMWLK equations in which both target and projectile are symmetrically treated. The structural aspects of the model may inspire future searches for corresponding structures in QCD.
