How to solve the Free Parameter Problem in SUSY ??
In Standard Model, we have 19 free parameters:
me Electron mass 511 keV
mμ Muon mass 106 MeV
mτ Tauon mass 1.78 GeV
mu Up quark mass () 1.9 MeV
md Down quark mass () 4.4 MeV
ms Strange quark mass () 87 MeV
mc Charm quark mass () 1.32 GeV
mb Bottom quark mass () 4.24 GeV
mt Top quark mass (on-shell scheme) 172.7 GeV
θ12 CKM 12-mixing angle 0.229
θ23 CKM 23-mixing angle 0.042
θ13 CKM 13-mixing angle 0.004
δ CKM CP-violating Phase 0.995
g1 U(1) gauge coupling () 0.357
g2 SU(2) gauge coupling () 0.652
g3 SU(3) gauge coupling () 1.221
θQCD QCD Vacuum Angle ~0
μ Higgs quadratic coupling Unknown
λ Higgs self-coupling strength Unknown
Note that We have even more (above 100) free parameters in Supersymmetric Models while we solved another problems of SM (hierarchy problem).
Is there a way to solve this problem in SUSY??
