How the Higgs potential got its shape
Jens Mund, Karl-Henning Rehren, Bert Schroer
String-localized quantum field theory allows renormalizable couplings involving massive vector bosons, without invoking negative-norm states and compensating ghosts. We analyze the…
Infraparticle quantum fields and the formation of photon clouds
Jens Mund, Karl-Henning Rehren, Bert Schroer
A non-perturbative and exactly solvable quantum field theoretical model for a "dressed Dirac field" is presented, that exhibits all the kinematical features of QED: an appropriate…
Gauss' Law and String-Localized Quantum Field Theory
Jens Mund, Karl-Henning Rehren, Bert Schroer
The quantum Gauss Law as an interacting field equation is a prominent feature of QED with eminent impact on its algebraic and superselection structure. It forces charged particles…
Positivity and causal localizability in higher spin quantum field theories
Bert Schroer
It is shown that the recently introduced positivity and causality preserving string-local quantum field theory (SLFT) resolves most No-Go situations in higher spin problems. This i…
Relations between positivity, localization and degrees of freedom: the Weinberg-Witten theorem and the van Dam-Veltman-Zakharov discontinuity
Jens Mund, Karl-Henning Rehren, Bert Schroer
The problem of accounting for the quantum degrees of freedom in passing from massive higher-spin potentials to massless ones and its inverse, the "fattening" of massless tensor pot…
Helicity decoupling in the massless limit of massive tensor fields
Jens Mund, Karl-Henning Rehren, Bert Schroer
Massive and massless potentials play an essential role in the perturbative formulation of particle interactions. Many difficulties arise due to the indefinite metric in gauge theor…
