Hello all. Again, thank you for the help so far. Forgive the lack of tex in this post, it somehow was creating errors no matter what I tried.
My question this time involves understanding the F and D terms in SUSY theories. From what I understood, they were introduced as auxiliary fields (EOM: [tex]F=F^{\dagger}=0[/tex] and [tex] D^{a}=0[/tex]) to ensure closure of the SUSY algebra on and off-shell.
At some point though when working out the superpotential for a supersymmetric gauge theory, the auxiliary terms are re-expressed in terms of scalar fields. When discussing EWSB in the MSSM, the D term gives the Higgs quartic self-interaction while the F term give: \mu(H_1)(H_2)
- Are the F and D terms thus physical then? What happened to the interpretation that they are fields integrated out and play no role in the EOM's? Why are these terms so important? I'm having a bit of trouble with these guys.
- From what I understand, the four relevant parameters in EWSB are tan{\beta}, \mu, m_1, m_2 which can be written in terms of free parameters in the SUSY breaking soft terms? - Shiro
