Compact Exotic Tetraquark Mesons in Large-NcQCD
EPJ Web of Conferences
We embark on systematic explorations of the behaviour of tetraquark mesons, i.e., colour-singlet bound states of two quarks and two antiquarks, in the (idealized) limit of a large number of colour degrees of freedom, N c , of quantum chromodynamics, QCD. Considering the scattering of two ordinary mesons into two ordinary mesons, we start off with formulating a set of selection criteria that should enable us to unambiguously single out precisely those contributions to all encountered scatteringdoi:10.1051/epjconf/201819104003 fatcat:bustqzkkgrdqfbmwl7utc4aznu
