Abstract
The description of the mass differences between the states of the
baryon octet with spin parity $(\frac{1}{2})^+$ and decuplet
$(\frac{3}{2})^+$ in terms of the chromomagnetic interaction
is extended to the mesons $0^-$ and $1^-$, to the
two lowest scalar tetraquarks and to the recently discovered
hidden charm pentaquarks discovered at LHCb with the result
to predict four states $(\frac{3}{2})^-$ with "open channel"
p $J/psi$ and $\Lambda_c \bar{D}^{*0}$ for the two lightest ones
and $\Sigma_c \bar{D}^*$ for the two heaviest ones.
