higgsino fields linearly mix with U(1) and SU(2)
gauginos leading to four
neutralinos and two
charginos that

While the two charginos...

Neutralinos and

-
superpartners of the
Standard Model fall into: squarks, gluinos, charginos,
neutralinos, and sleptons.
These superparticles have
their interactions and subsequent...

Majorana fermions, such as the

mixture of
