Other properties, such as its lifetime or production and decay mechanisms, have not yet been established, but the system of two heavy quarks and one light quark is expected to behave differently from other baryons.
The relatively high mass of the new particles suggests that quarks with more mass are better at binding into big groups, Stone says.
The existence of quark excited states, though not yet directly discovered, has been investigated over three decades [16-18].

Skwarnicki adds that even though these particles don't exist freely in nature, they may have played a role in the very early universe, when a hot, dense soup of quarks and gluons cooled and condensed into nature's first multi-quark matter.

Leptons, however, are fundamental particles, which cannot be broken down into simpler ones (as far as we now know), while hadrons are composite particles and are made up of quarks.
