A Supersymmetric Composite Model with Dynamical Supersymmetry Breaking
Abstract
We present a supersymmetric composite model with dynamical supersymmetry breaking. The model is based on the gauge group
SU(2
)
S
×SU(2
)
H
×SU(3
)
c
×SU(2
)
L
×U(1
)
Y
. Supersymmetry is dynamically broken by the non-perturbative effect of the
SU(2
)
S
`supercolor' interaction. The large top Yukawa coupling is naturally generated by the
SU(2
)
H
`hypercolor' interaction as recently proposed by Nelson and Strassler. The supersymmetry breaking is mediated to the standard model sector by a new mechanism. The electroweak symmetry breaking is caused by the radiative correction due to the large top Yukawa coupling with the supersymmetry breaking. This is the `radiative breaking scenario', which originates from the dynamics of the supercolor and hypercolor gauge interactions.
