  A number of new four-quark states containing from one to four charm or
anti-charm quarks have been observed recently. Many of these new states have
been discovered at the LHC. The production of these states via intrinsic charm
in the proton is investigated. The tetraquark masses obtained in this approach,
while dependent on the internal transverse momenta of the partons in the state,
are shown to agree well with the measured masses. These calculations can
provide some insight into the nature of the tetraquark candidates, whether as a
bound meson pair or as a looser configuration of four individual partons. The
kinematic distributions of these states as a function of rapidity and
transverse momentum are also studied. The possible cross sections for these
states are finally considered.
