    Weyl version of the Rarita-schwinger equation

    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?

    Weyl version of the Rarita-schwinger equation

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

    How to make an action supersymmetric?

    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

    Proof of a Fierz identity

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

    Lagrangian of QCD

    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

    Eta particle

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