A zero–dimensional model for high–energy scattering in QCD
We investigate a zero–dimensional toy model originally introduced by Mueller and Salam [1] which mimics high–energy scattering in QCD in the presence of both gluon saturation and gluon number fluctuations, and hence of Pomeron loops. Unlike other toy models of the reaction–diffusion type, the model studied in this paper is consistent with boost invariance and, related to that, it exhibits the s...
متن کاملZero dimensional model for determining particle and energy densities of P-11B fusion reaction in radiotherapy
Three alpha particles are emitted from the P-11B fusion reaction. Alpha particles play an important role in the death of cancer cells. When boron is accumulated in the tumor, protons irradiated out of body can react with the boron in the tumor. Also a fast gamma ray of 719 KeV beam is released from the P-11B fusion reaction which plays a useful role for us. This therapeutic approach includes fe...
متن کاملOne–dimensional model for QCD at high energy
We propose a stochastic particle model in (1+1)–dimensions, with one dimension corresponding to rapidity and the other one to the transverse size of a dipole in QCD, which mimics high–energy evolution and scattering in QCD in the presence of both saturation and particle–number fluctuations, and hence of Pomeron loops. The model evolves via non–linear particle splitting, with a non–local splitti...
متن کاملScattering Amplitudes in High Energy QCD
We develop a new systematic procedure for the Regge limit in perturbative QCD to arbitrary logarithmic order. The formalism relies on the IR structure and the gauge symmetry of the theory. We identify leading regions in loop momentum space responsible for the singular structure of the amplitudes and perform power counting to determine the strength of these divergences. Using a factorization pro...
متن کاملSoft High Energy Scattering in Nonperturbative Qcd
In this report diffractive high energy reactions are discussed in a functional integral approach where hadronic amplitudes are calculated from vacuum expectation values of lightlike Wegner-Wilson loops. In the first part we calculate elastic differential cross sections for high energy and small momentum transfer elastic protonproton (pp) scattering which are in reasonable agreement with the exp...
