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 important for this physics. With an integrated luminosity of 1 fb, collected by 2005, HERA will remain a competitive and potentially fruitful facility for new physics searches.

We present a QCD sum rule calculation of the strange-quark mass including four-loop QCD corrections to the correlator of scalar currents. We obtain ¯ m s (1 GeV) = 205.5 ± 19.1 MeV.

We investigate the five and six-dimensional black strings within EinsteinMaxwell theory. The extremal black strings are endowed with the null Killing symmetry. We study the propagation of Einstein-Maxwell modes in the extremal black string background by using this symmetry. It turns out that one graviton is a propagating mode, while both the Maxwell(F) and three-form (H) fields are non-propagat...
