  The spin-charge-family theory, in which spinors carry besides the Dirac spin
also the second kind of the Clifford object, no charges, is a kind of the
Kaluza-Klein theories. The Dirac spinors of one Weyl representation in
$d=(13+1)$ manifest in $d=(3+1)$ at low energies all the properties of quarks
and leptons assumed by the standard model. The second kind of spins explains
the origin of families. Spinors interact with the vielbeins and the two kinds
of the spin connection fields, the gauge fields of the two kinds of the
Clifford objects, which manifest in $d=(3+1)$ besides the gravity and the known
gauge vector fields also several scalar gauge fields. Scalars with the space
index $s\in (7,8)$ carry the weak charge and the hyper charge ($\mp
\frac{1}{2}, \pm \frac{1}{2}$, respectively), explaining the origin of the
Higgs and the Yukawa couplings. It is demonstrated in this paper that the
scalar fields with the space index $t\in (9,10,\dots,14)$ carry the triplet
colour charges, causing transitions of antileptons and antiquarks into quarks
and back, enabling the appearance and the decay of baryons. These scalar fields
are offering in the presence of the right handed neutrino condensate, which
breaks the ${\cal C}{\cal P}$ symmetry, the answer to the question about the
matter-antimatter asymmetry.
