TLDR
In this paper, Schur's Lemma and Orthogonality Relations are used for partial wave and fermion problems. But they do not specify the relationship between the two functions.Abstract:

Cosmic abundances of stable particles: Improved analysis
TL;DR: An exact relativistic single-integral formula for the thermal average of the annihilation cross section times velocity, the key quantity in the determination of the cosmic relic abundance of a species, is obtained in this paper.
Journal ArticleDOI
Unitarity limits on the mass and radius of dark-matter particles
TL;DR: Using partial wave unitarity and the observed density of the Universe, it is show that a stable elementary particle which was once in thermal equilibrium cannot have a mass greater than 340 TeV.

Formation of Superdense Hadronic Matter in High-Energy Heavy-Ion Collisions
Bao-An Li,Che Ming Ko +1 more
TL;DR: A newly developed relativistic transport model for high energy heavy-ion collisions shows that in central collisions there exists a large volume of sufficiently long-lived superdenseHadronic matter whose local baryon and energy densities exceed the critical densities for the hadronic matter to quark-gluon plasma transition.

Pionic modes of excitation in nuclei
TL;DR: A unified treatment of pionic nuclear excitations both at low energy (ω«m π ) and at scattering energies (mπ ≲ ω ≲ 3 m π) is presented in this article.

Nucleons, mesons and deltas in nuclear-matter - a relativistic dirac-brueckner approach
B Terhaar,R Malfliet +1 more
TL;DR: In this paper, the relativistic Dirac-Brueckner approach was used to study the properties of both dense and hot symmetric nuclear matter, and the saturation point was found to lie on a Coester line which goes through the empirical value for nuclear matter.
