Evaluation of Entanglement Entropy in High Energy Elastic Scattering
Robi Peschanski, Shigenori Seki
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 evalu…
Profile of a Galactic Spherical Cloud of Self-Gravitating Fermions
B. G. Giraud, R. Peschanski
The field which binds a thermal fermionic cloud is defined as a Hartree integral upon its density. In turn, the density results from the field via a Thomas-Fermi occupation of the…
Positivity and unitarity constraints on dipole gluon distributions
Robi Peschanski
In the high-energy domain, gluon transverse-momentum dependent distributions in nuclei obey constraints coming from positivity and unitarity of the colorless QCD dipole distributio…
Fourier-positivity constraints on QCD dipole models
Bertrand G. Giraud, Robi Peschanski
Fourier-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-s…
Entanglement Entropy of Scattering Particles
Robi Peschanski, Shigenori Seki
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 expansio…
From "Dirac combs" to Fourier-positivity
Bertrand G. Giraud, Robi Peschanski
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.…
