T mesons are hypothetical mesons composed of a top quark and either an up (T⁰), down (T⁺), strange (T+s), charm (T0c) or bottom antiquark (T+b). Because of the top quark's short lifetime, T mesons are not expected to be found in nature. The combination of a top quark and top antiquark is not an open T meson, but rather a closed top-quark meson called toponium. Each T meson has an antiparticle that is composed of a top antiquark and an up (T⁰), down (T⁻), strange (T−s), charm quark (T0c) or bottom quark (T−b) respectively.
