Measuring quark colour operator

  • #1

Main Question or Discussion Point

What is the explicit 3x3 matrix operator which measures the colour of a quark? Essentially what I want to know is what is the analogue of ##S^z## for the measuring of spin.

The colour charges are not distinguishable, it is therefore not possible to measure "colour projections" in the same way that one could measure spin projections with a stern gerlach experiment - is this what you are asking?

the (mathematical) analogue to Sz are the 2 diagonal (commute with all the rest matrices in the repr) Gellmann matrices, but I don't think that's what you asked...
