In the context of random multiplicative energy cascade processes, we derive analytical expressions for translationally invariant oneand two-point cumulants in logarithmic field amplitudes. Suchâ€¦ (More)

Geometrical random multiplicative cascade processes are often used to model positivevalued multifractal fields such as the energy dissipation in fully developed turbulence. We propose a dynamicalâ€¦ (More)

Geometrical random multiplicative cascade processes are often used to model positivevalued multifractal fields such as for example the energy dissipation field of fully developed turbulence. Aâ€¦ (More)

We introduce Q-space, the tensor product of an index space with a primary space, to achieve a more general mathematical description of correlations in terms of q-tuples. Topics discussed include theâ€¦ (More)

We review the basic notion of correlations in point processes, adapted to the language of high energy physicists. The measurement of accessible information on correlations by means of correlationâ€¦ (More)

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 example of theâ€¦ (More)

Discussions about Bose-Einstein correlations between decay products of coproduced W-bosons again raise the question about the behaviour of correlations if several strings are produced. This isâ€¦ (More)

We have made a detailed and quantitative study of dilepton production via bremsstrahlung of a virtual photon during pion-pion collisions. Most calculations of electromagnetic radiation from strongâ€¦ (More)

The traditional calculation of dilepton yields from bremsstrahlung relies on the assumption that electromagnetic and strong processes factorize. We argue that this assumption, embodied by the softâ€¦ (More)
