WebbIts antiparticle (containing a strange quark and a down antiquark) has the same mass. It is clear from the quark model assignments that the kaons form two doublets of isospin; that is, they belong to the fundamental representation of SU(2) called the 2. One doublet of strangeness +1 contains the K + and the K 0. The antiparticles form the other ... Webb19 maj 2012 · The quark model was formulated in 1964 to classify mesons as bound states made of a quark–antiquark pair, and baryons as bound states made of three quarks.
