How to form a J^{PC} = 1^{--} state with only gluons?
Two gluons? Three ?
How do the P, C, J values work?

The quantum number J^{PC} = 1^{-} refers to the total angular momentum, parity, and charge conjugation of a particle. While gluons themselves are spin-1 particles, their collective interactions and configurations can result in a J^{PC} state. This is similar to how protons and neutrons, which are made up of quarks, can have well-defined quantum numbers.
Forming a J^{PC} = 1^{-} state with only gluons is important for understanding the properties and behavior of gluons, which are the carriers of the strong nuclear force. This can provide insight into the structure of the strong force and its role in the formation of hadrons (particles made up of quarks and gluons).
Yes, this J^{PC} = 1^{-} state can be observed experimentally through the production and decay of particles. For example, experiments at the Large Hadron Collider (LHC) have observed J^{PC} = 1^{-} states composed of gluons in collisions between protons.
While it is theoretically possible to form a J^{PC} = 1^{-} state with only gluons, it is a difficult task and has not yet been achieved in experiments. This is because gluons have a property called color charge, which makes it difficult to isolate them from other particles and form a pure state.
QCD is the theory that describes the strong nuclear force and the interactions of quarks and gluons. By forming a J^{PC} = 1^{-} state with only gluons, scientists can test and validate the predictions of QCD and further our understanding of the fundamental forces of nature.
