In General > s.a. dark
matter; particle types; susy field
theories.
* Expectation and bounds:
From LEP, ms > 100 GeV, and
the expectation is that ms > mZ.
* 1996: For most theorists
it is there, in some form, at some
energies; Claim by CDF of ee ![]()
event
that must be explained by susy – went
away.
* 2000: The energy required to produce sparticles should not be much
higher than that of present accelerators.
* 2001: Anomalous
magnetic
moment reported by BNL experiment – went away; Despite the absence of
any experimental evidence, it is considered by many physicists as 'about to
be discovered'.
* 2002: New lower bound of 195 GeV on gluino mass.
* 2004: Indirect hints
from experiment point toward a supersymmetry breaking scale just above the
electroweak scale (successful prediction of gauge
coupling
unification, observed value of the top quark mass just below the supersymmetric
fixed point value, observed pattern of electroweak symmetry breaking, absence
of large corrections to precision measurements in the electroweak
sector,
and b-quark–
-lepton
unification); If correct, sparticles may be discovered at the Tevatron
Run II at
Fermilab, but almost
certainly at the LHC at CERN starting in 2007, and then we should be
able to
either confirm or (fapp) rule out susy; A number of interesting processes
will be probed once superpartners are discovered, including the existence of
a fermionic Goldstone particle associated with spontaneous supersymmetry
breaking, and supersymmetric flavor violation, which should provide insights
into the underlying mechanism of supersymmetry breaking.
From Supergravity > s.a. black
holes; supergravity.
* Consequences: If one
does not want extra gravitons, the maximum spacetime dimension is 11; Long
range gravitational forces are not affected, only the short
range ones; The graviton, quarks and other particles acquire a superpartner.
