The double-charm tetraquark (T+
cc
, ccud) is a type of long-lived tetraquark that was discovered in 2021 in the LHCb experiment conducted at the Large Hadron Collider. It contains four quarks: two charm quarks, an anti-up and an anti-down quark.

It has a theoretical computed mass of 3868±124 MeV/c2. The discovery showed an exceptionally strong peak, with 20-sigma significance.

It is hypothesized that studying the behavior of the double-charm tetraquark may play a part in explaining the behavior of the strong force. Following the discovery of the T+
cc
, researchers now plan experiments to find its double-beauty counterpart Tbb. This tetraquark has been found to have a longer lifespan than most known exotic-matter particles.
