Another important particle type is the meson;

Exotic hadrons like pentaquarks(four quarks, one antiquark) and tetraquarks(two quarks, two antiquarks)
are also classified as baryons and Mesons depending on their baryon number.
Or were there instead two clusters- one three-quark baryon and a meson(the particle made of a quark and an antiquark) that interacted with each other?
Muon was previously called mu Mesons, but modern muon particles are not
classified as mu Mesons by physicists, and the name is no longer used by the physics community.

Salam's notable achievements include the Pati-Salam model, magnetic photon,
vector meson, Grand Unified Theory,
work on supersymmetry and, most importantly, electroweak theory, for which he was awarded the Nobel Prize.
