LHCb experiment reports observation of exotic pentaquark particles
Illustration of the possible layout of the quarks in a pentaquark particle such as those discovered at LHCb. The five quarks might be tightly bonded. They might also be assembled into a meson (one quark and one antiquark) and a baryon (three quarks), weakly bonded together.
