Spacetime foam and high-energy photons
F. R. Klinkhamer, C. Rupp
It is shown that high-energy astrophysics can provide information on the small-scale structure of spacetime.
Photon-propagation model with random background field: Length scales and Cherenkov limits
F. R. Klinkhamer, C. Rupp
We present improved experimental bounds on typical length scales of a photon-propagation model with a frozen (time-independent) random background field, which could result from ano…
A sphaleron for the non-Abelian anomaly
F. R. Klinkhamer, C. Rupp
A self-consistent Ansatz for a new sphaleron of SU(3) Yang-Mills-Higgs theory is presented. With a single triplet of Weyl fermions added, there exists, most likely, one pair of fer…
Spacetime foam, CPT anomaly, and photon propagation
F. R. Klinkhamer, C. Rupp
The CPT anomaly of certain chiral gauge theories has been established previously for flat multiply connected spacetime manifolds M of the type R^3 x S^1, where the noncontractible…
Sphalerons, spectral flow, and anomalies
F. R. Klinkhamer, C. Rupp
The topology of configuration space may be responsible in part for the existence of sphalerons. Here, sphalerons are defined to be static but unstable finite-energy solutions of th…
Supersymmetric Yang-Mills theories with local coupling: The supersymmetric gauge
E. Kraus, C. Rupp, K. Sibold
Supersymmetric pure Yang-Mills theory is formulated with a local, i.e. space-time dependent, complex coupling in superspace. Super-Yang-Mills theories with local coupling have an a…
