yes you're right. what if i want to express it in terms of sigmas instead of gamma matrices. by what i can replace the levi-civita?

i want the expression in terms of two component spinors and not Dirac spinors.

Hello, Can someone please give me the form of the "Weyl" version of the Rarita-Schwinger equation. Thanks

Thanks

Hello, i am given an action (only scalars) and i want to make it supersymmetric. Any hints? Do i simply add fermionic terms similar to those of the bosonic? Thanks

No, not really. Thanks anyway

Hello, how can i prove by "fierzing" twice that (\bar{\lambda} \gamma_5 \lambda) \lambda = - (\bar{\lambda} \lambda) (\gamma_5 \lambda)? Thanks

Hello, In the lagrangian of QCD, there is q which is the quark field and it is the fundamental representation of SU(3). This q is multiplied by a gamma matrix and a q bar. So, how can we have a 4x4 matrix multiplying 1x3 matrix? Thanks

Thanks

Hello, May you please provide me with a good reference that explains supersymmetric QCD, and dicusses the association of the superfields with the particles. Thanks

What does S^5 sphere mean? How can I imagine it? Thanks

How can we find a parametrization for SU(3) in terms of angles?

Great, Thanks

Can you please specify for me a reference to check? Thanks

Why is the eta particle written as 1/sqrt(6) *(uu(bar) + dd(bar) -2ss(bar))? Thanks
