First, we recollect the model of algebraically composite Dirac-type pa
rticles, leading to three families of leptons and quarks as well as to
two hypothetical families of Yukawa scalars. Then, we briefly discuss
new hadrons involving colored quark-like Yukawa scalars as their cons
tituents. When denoting such scalars by y, these (colorless) hadrons a
re: (yyBAR), (qyBAR) (both with B = 0, L = 0) and (yyy), (qyy), (qqy)
(all three with B = 1, L = 0). The lowest-in-mass versions of them hav
e the J(P)(I)-signatures: 0+(0, 1), 1/2+(0, 1) and 0-(3/2), 1/2+(1/2),
0+(1/2) [or 1+(1/2, 3/2)], respectively. Among them, (qyBAR) may be t
he only states stable in strong interactions (for adequate masses).
