ADS/CFT String Duality and Conformal Gauge Field Theories
Compactification of Type IIB superstring on an
background leads to SU(N) gauge field theories with prescribed matter
representations. In the 't Hooft limit of large N such theories are conformally
finite. For finite N and broken supersymmetry ( = 0) I derive the
constraints to be two-loop conformal and examine the consequences for a wide
choice of and its embedding .Comment: 10 pages LaTe
Predicted modulated differential rates for direct WIMP searches at low energy transfers
The differential event rate for direct detection of dark matter, both the
time averaged and the modulated one due to the motion of the Earth, are
discussed. The calculations focus on relatively light cold dark matter
candidates (WIMP) and low energy transfers. It is shown that for sufficiently
light WIMPs the extraction of relatively large nucleon cross sections is
possible. Furthermore for some WIMP masses the modulation amplitude may change
sign, meaning that, in such a case, the maximum rate may occur six months later
than naively expected. This effect can be exploited to yield information about
the mass of the dark matter candidate, if and when the observation of the
modulation of the event rate is established.Comment: 16 pages, 22 figures; references adde
