El Hombre Invisible said:I doubt it. Unless it were two quark-antiquark pairs, which annihilate straight away, color would not be confined.

Pentaquark particles are hypothetical subatomic particles made up of five quarks, which are fundamental particles that make up protons and neutrons. They were first proposed in the 1960s but have yet to be observed in experiments.
The recent experiment was conducted at the Large Hadron Collider (LHC) in Switzerland by the LHCb collaboration. They observed a particle that was initially thought to be a pentaquark, but further analysis showed that it was likely a combination of two other particles.
Previous experiments, such as those at the Thomas Jefferson National Accelerator Facility, had seen hints of pentaquark particles in their data. Additionally, some theoretical models predicted the existence of pentaquark particles.
No, the recent experiment does not completely rule out the existence of pentaquark particles. It does, however, cast doubt on their existence and suggests that previous evidence may have been misinterpreted or influenced by other factors.
The next steps will involve further analysis of data from the LHC and other experiments, as well as the development of more precise and sophisticated theoretical models. It is also possible that future experiments, such as the Electron-Ion Collider in the United States, may provide more definitive evidence for or against the existence of pentaquark particles.
