How are gluons related to the generators of SU(3),(adsbygoogle = window.adsbygoogle || []).push({});

the Gell-Mann matrices?

I do not understand how the structure constants f and d

describe how, for example, a red-antigreen gluon transforms

into a red-antiblue and a blue-antigreen one.

Do the f or the d factors describe the three-gluon vertices?

Or both? And where do 4-gluon vertices come in?

Thank you in advance for any help!
