Supersymmetry & Top’s Superpartner
ØSupersymmetry
•proposed new symmetry of Nature. (Originated in
superstring and supergravity theories)
•predicts that every SM particle
has a superpartner with the same quantum numbers but spin. Spin
differs by ½.
ØNo superelectron with m=0.5 MeV & spin
0 has been observed à SUSY is broken @ or above EWK scale
ØMasses of
superpartners are to be determined by experiment
ØSUSY predicts top’s superpartner being
potentially the lightest among superquarks
