Dynamical Instabilities of Brane World Models
J. Diemand, Ch. Mathys, D. Wyler
We show the instability of two self-tuning brane world models with gauge invariant linear perturbation theory. This general method confirms a known instability of the original mode…
Indirect search for supersymmetry in rare B decays
C. Greub, T. Hurth, D. Wyler
QCD corrections to the gluino induced contribution to b --> s gamma are shown to be important in order to extract reliable bounds on the off-diagonal elements of the squark mass ma…
1995-96 HERA Workshop; Beyond the Standard Model Group Summary
H. Dreiner, H. -U. Martyn, S. Ritz +1
We summarize the work done in the ``Beyond the Standard Model'' group of the 1995-96 HERA Workshop. Of the various proposed HERA upgrades, the luminosity improvement is the most im…
Unitary Background Gauges and Hamiltonian approach to Yang--Mills Theories
A. Dubin, D. Wyler
A variety of unitary gauges for perturbation theory in a background field is considered in order to find those most suitable for a Hamiltonian treatment of the system. We select tw…
