D-instantons and multiparticle production in N=4 SYM (2009)
N=4 Super-symmetric Yang-Mills theory (N=4 SYM) in the strong coupling regime has been successfully applied (through the AdS/CFT correspondence) to the description of strongly coupled plasma which is...
Dynamics Simulation Model for Space Tethers (2006)
Levin, E.M., Pearson, J., Oldson, J.C.
This document describes the development of an accurate model for the dynamics of the Momentum Exchange Electrodynamic Reboost (MXER) system. The MXER is a rotating tether about 100-km long in...

The BFKL Pomeron in 2+1 Dimensional QCD (1998)
Ivanov, D. Yu., Kirschner, R., Levin, E. M., Lipatov, L. N., Szymanowski, L., Wüsthoff, M.
We investigate the high-energy scattering in the spontaneously broken Yang - Mills gauge theory in 2+1 space--time dimensions and present the exact solution of the leading $\ln s$ BFKL equation. The...
Scaling violation and shadowing corrections at HERA (1997)
Filho, A. L. Ayala, Ducati, M. B. Gay, Levin, E. M.
We study the value of shadowing corrections (SC) in HERA kinematic region in Glauber - Mueller approach. Since the Glauber - Mueller approach was proven in perturbative QCD in the double logarithmic...
A unitarity bound and the components of photon - proton interactions (1997)
Gotsman, E., Levin, E. M., Maor, U.
We show how and why the small distance ("hard") interaction, calculable in perturbative QCD, provides a mass cutoff in Gribov's formula for photon-proton collisions. This enables us to find a new and...
Vector Meson production in ep -> epV (1996)
Koepf, W., Landshoff, P. V., Levin, E. M., Nikolaev, N. N.
The diffractive production of vector mesons in ep interactions at low x is a subject of heated debates. This chapter consists of four contributions written by the original authors and expresses the...
Gluon density in nuclei (1996)
Ayala, A. L., Ducati, M. B. Gay, Levin, E. M.
In this talk we present our detail study ( theory and numbers) [1] on the shadowing corrections to the gluon structure functions for nuclei. Starting from rather contraversial information on the...
Froissart boundary for deep inelastic structure functions (1996)
Ayala, A. L., Ducati, M. B. Gay, Levin, E. M.
In this letter we derive the Froissart boundary in QCD for the deep inelastic structure function in low $x$ kinematic region. We show that the comparison of the Froissart boundary with the new HERA...
Diffractive open charm production at HERA (1996)
Levin, E. M., Martin, A. D., Ryskin, M. G., Teubner, T.
We use perturbative QCD to calculate the cross sections $\sigma^{L,T}$ for the diffractive production of open charm $(c\overline{c})$ from longitudinally and transversely polarised photons (of...
QCD evolution of the gluon density in a nucleus (1996)
Ayala, A. L., Ducati, M. B. Gay, Levin, E. M.
The Glauber approach to the gluon density in a nucleus, suggested by A. Mueller, is developed and studied in detail. Using the GRV parameterization for the gluon density in a nucleon, the value as...
A Screened BFKL Interpretation of $F_2$ in the Exceedingly Small x Limit (1995)
Gotsman, E., Levin, E. M., Maor, U.
In this letter we show that the behaviour of $F_{2}$, at very small $x_B$, agrees with the behaviour expected from the BFKL evolution equation, when screening corrections are included. We obtain a...
Diffractive $J/\psi$ photoproduction as a probe of the gluon density (1995)
Ryskin, M. G., Roberts, R. G., Martin, A. D., Levin, E. M.
We use perturbative QCD, beyond the leading $\ln Q^2$ approximation, to show how measurements of diffractive $J/\psi$ production at HERA can provide a sensitive probe of the gluon density of the...
EFFECTS OF SHADOWING IN DOUBLE POMERON EXCHANGE PROCESSES (1995)
Gotsman, E., Levin, E. M., Maor, U.
The effects of shadowing in double Pomeron exchange processes are investigated within an eikonal approach with a Gaussian input. Damping factors due to screening are calculated for this process and...
