Fourier-positivity (F-positivity), i.e. the mathematical property that a function has a positive Fourier transform, can be used as a constraint on the parametrization of QCD dipole-target cross-sections or Wilson line correlators in transverse positi

We study the entanglement entropy between the two outgoing particles in an elastic scattering process. It is formulated within an S-matrix formalism using the partial wave expansion of two-body states, which plays a significant role in our computatio

Entanglement of the two scattered particles is expected to occur in elastic collisions, even at high energy where they are in competition with inelastic ones. We study how to evaluate quantitatively the corresponding entanglement entropy $S_{\rm EE}.

In the high-energy domain, gluon transverse-momentum dependent distributions in nuclei obey constraints coming from positivity and unitarity of the colorless QCD dipole distributions through Fourier-Bessel transformations. Using mathematical properti

We present a general solution of relativistic ( 1 + 1 ) -dimensional hydrodynamics for a perfect fluid flowing along the longitudinal direction as a function of time, uniformly in transverse space. The Khalatnikov potential is expressed as a linear c

We first recall the classical “t-channel” vs. “s-channel” approaches to soft high energy diffraction. We then mention Hard Diffraction and its relation to QCD and some aspects of factorisation breaking at Hera and the Tevatron. Finally we dis

Motivated by various problems in physics and applied mathematics, we look for constraints and properties of real Fourier-positive functions, i.e. with positive Fourier transforms. Properties of the "Dirac comb" distribution and of its tensor products

We review some of the motivations for the use of the AdS/CFT correspondence in the study of heavy ion collisions, and also the fluid/gravity correspondence. Then, we discuss our results about thermalization of a strongly coupled Quark-Gluon-Plasma.
