Braid group statistics implies scattering in three-dimensional local quantum physics
Jacques Bros, Jens Mund
It is shown that particles with braid group statistics (Plektons) in three-dimensional space-time cannot be free, in a quite elementary sense: They must exhibit elastic two-particl…
Anti de Sitter quantum field theory and a new class of hypergeometric identities
Jacques Bros, Henri Epstein, Michel Gaudin +2
We use Anti-de Sitter quantum field theory to prove a new class of identities between hypergeometric functions related to the Källén-Lehmann representation of products of two Anti-…
Scalar tachyons in the de Sitter universe
Jacques Bros, Henri Epstein, Ugo Moschella
We provide a construction of a class of local and de Sitter covariant tachyonic quantum fields which exist for discrete negative values of the squared mass parameter and which have…
Nonlocal potentials and complex angular momentum theory
J. Bros, E. De Micheli, G. A. Viano
The purpose of this paper is to establish meromorphy properties of the partial scattering amplitude T(lambda,k) associated with physically relevant classes N_{w,alpha}^gamma of non…
Triangular invariants, three-point functions and particle stability on the de Sitter universe
Jacques Bros, Henri Epstein, Michel Gaudin +2
We study a class of three-point functions on the de Sitter universe and on the asymptotic cone. A blending of geometrical ideas and analytic methods is used to compute some remarka…
Particle decays and stability on the de Sitter universe
Jacques Bros, Henri Epstein, Ugo Moschella
We study particle decay in de Sitter space-time as given by first order perturbation theory in a Lagrangian interacting quantum field theory. We study in detail the adiabatic limit…
