Removing the gauge parameter dependence of the effective potential by a field redefinition

N. K. Nielsen

The gauge parameter dependence of the effective potential is determined by partial differential equations involving also the Higgs boson field expectation value. Solving these equa…

Higgs boson decay into two photons in an electromagnetic background

N. K. Nielsen

The amplitude for Higgs boson decay into two photons in a homogeneous and time-independent magnetic field is investigated by proper-time regularization in a gauge invariant manner…

The Einstein-Maxwell system, Ward identities, and the Vilkovisky construction

N. K. Nielsen

The gauge fixing dependence of the one-loop effective action of quantum gravity in the proper-time representation is investigated for a space of arbitrary curvature, and the invest…

Instanton constraints in supersymmetric gauge theories II. N=2 Yang-Mills theory

N. K. Nielsen

The analysis in previous publications of the instanton constraints required to produce a finite action of the theory is carried out also for N=2 supersymmetric Yang-Mills theory.

On the Origin of Kaluza's Idea of Unification

Y. Verbin, N. K. Nielsen

We argue that the starting point of Kaluza's idea of unifying electrodynamics and gravity was the analogy between gravitation and electromagnetism which was pointed out by Einstein…

Alternative approaches to the Casalbuoni-Brink-Schwarz Superparticle

Morten Nielsen, N. K. Nielsen

Wigner's method of induced representations is applied to the N=1 super-Poincare group, and by using a state corresponding to the basic vector of the little group as a Clifford vacu…
