Why can't there be other Boson particle clusters

[Dalis]

I most recently heard about the new mathematics that help predict glueballs properties better. I had the really strange question of, why can't all other bosons have a cluster particle, like the glueball. Is it due to there force strength over distance or am I missing something.

Gluons interact with other gluons. Photons and Z bosons do not interact with other photons and Z bosons. W bosons and Higgs bosons can interact with other W bosons and Higgs bosons. So maybe you could have some clustering there, but they are not stable.

W, Z and H are too short-living, and photons have no relevant self-interactions.

Edit: Too slow.
