Supersymmetri Partile Searhes
Limits are based on the Minimal Supersymmetri Standard Model
(MSSM) with additional assumptions as follows:
1) χe01 (or γe) is lightest supersymmetri partile; 2) R-parity is onserved;
3) With the exeption of et and eb, all salar quarks are assumed to be
degenerate in mass and m qeR = m qeL . 4) Limits for harged sleptons refer
to the eℓR states. 5) Unless otherwise stated, gaugino mass uniation
at the GUT sale is assumed. For squarks and gluinos, the Constrained
MSSM (CMSSM) limits and simplied model limits are presented.
See the Partile Listings for a Note giving details of supersymmetry.

The rst of these limits is within CMSSM with asade deays, evaluated assuming a xed value of the parameters µ

squarks (eqL and qeR ) and gaugino mass parameters that are
onstrained by the uniation ondition at the grand uniation sale. The seond limit assumes a simplied model with
