i) how many Higgsinos there are (since the MSSM has 2 complex isodoublets)

ii) how many Higgsinos there are after EWSB and you gauge away three of the scalar fields

iii) their structure (Weyl, Dirac, Majorana)

Question 2: Question 1 arose after I heard that the deeper reason the Higgs is protected from large corrections is due to chiral symmetry of the Higgsino. I thought a bit about it, and figured it had something to do with the Higgsino exhibiting chiral symmetry and SUSY enforcing mass degeneracy.

Thanks!
