You are right, sorry. I am looking for example at the lower right box of Tab. 3 of https://arxiv.org/pdf/1008.4884.pdf In the B-violating operator I have terms that goes (neglecting colour and SU(2) indices, and noting that Dirac indices are always contracted within the brakets) like $$d^T C...

I have a really naive question that I didn't manage to explain to myself. If I consider SUSY theory without R-parity conservation there exist an operator that mediates proton decay. This operator is $$u^c d^c \tilde d^c $$ where ##\tilde d## is the scalar superpartner of down quark. Now...

Thank you very much!

Hi, I am struggling to derive the relations on the right hand column of eq.(4) in https://arxiv.org/pdf/1008.4884.pdfEven the easy abelian one (third row) which is $$D_\rho B_{\mu\nu}=\partial_\rho B_{\mu\nu}$$ doesn't match my calculation Since $$D_\rho B_{\mu\nu}=(\partial_\rho+i g...

Hi All, Sorry for my silence but I've been offline for a bit. So, to rephrase it a bit, I could say that I don't understand the CP properties transformation of the gluon fields strength tensor, since it seems to me that the derivative part and the pure non-abelian part (the G^2 term) have...

Hi, I am trying to figure out why a term like ## L \sim i \bar \psi_L \sigma^{\mu\nu}G_{\mu\nu}^a t^a \psi_R + h.c=## ##= i \bar \psi_L \sigma^{\mu\nu}G_{\mu\nu}^a t^a \psi_R - i \bar \psi_R \sigma^{\mu\nu}G_{\mu\nu}^a t^a \psi_L ## violates CP by looking at all the terms composing the...
