  At this point it is still unclear whether pentaquarks exist. While they have
be seen in some experiments there are many experiments in which they are not
found. On the assumption that pentaquarks exist, several authors have studied
the properties of pentaquarks. One description considered is that of
pentaquarks which consist of a diquark coupled to a triquark. There is a quite
extensive literature concerning the properties of diquarks and their importance
in the description of the nucleon has been considered by several authors. On
the other hand, there is little work reported concerning the description of
triquarks. In the present work we study a model for the triquark in which it is
composed of a component which contains a quark coupled to a scalar diquark and
another two components in which there is a quark coupled to a kaon. We solve
for the wave function of the triquark and obtain a mass for the triquark of
0.81 GeV which is quite close to the value of 0.80 GeV obtained in a QCD sum
rule study of triquark properties.
