Analytical solution for multivariate statistics in random multiplicative cascades

H. C. Eggers, M. Greiner, P. Lipa

It has long been a puzzle how to solve random multiplicative cascade structures analytically. We present an analytical solution found recently in the form of a simple pedagogical e…

QCD '98: status of the power corrections

V. I. Zakharov

We review status of the power corrections in QCD. The topics include shape variables, unconventional 1/Q^2 corrections, tachyonic gluon mass as a fit parameter to the 1/Q^2 correct…

Complete Helicity Decomposition of the B-t-tbar Vertex including Higher Order QCD Corrections and Applications to e+e- --> t tbar

Bodo Lampe

The complete density matrix for all polarization configurations in the process B--> t tbar, where B is an off--shell Z or photon and t is the top quark, is calculated numerically i…

Bremsstrahlung of a Quark Propagating through a Nucleus

B. Z. Kopeliovich, A. Schaefer, A. V. Tarasov

The density of gluons produced in the central rapidity region of a heavy ion collision is poorly known. We investigate the influence of the effects of quantum coherence on the tran…

Neutron-Antineutron Oscillations in Nuclei Revisited

Joerg Huefner, Boris Kopeliovich

An upper limit on oscillations can be obtained from the stability of matter. This relation has been worked out theoretically and together with data yields $τ_{n\bar n} >…

QCD Tests in High Energy Collisions

I. Bertram, T. Carli, G. Gustafson +1

Recent measurements and theoretical developments on the hadronic final state in deep-inelastic scattering, pp and ee collisions are presented.
