Dark matter is still a subject of ongoing debate. It has been considered in the theoretical description of compact objects such as neutron stars with cores of very dense matter. Various candidates for dark matter have been proposed in the scientific literature. Among them, the sexaquark has been identified as a potential boson particle that can form in the neutron star material based on its mass properties. We investigate the viability of the sexquark as a candidate for dark matter, especially under certain density conditions. Addressing the challenges associated with the formation of a boson particle in a highly dense medium without compromising the stability of the neutron star. A direct linear mass change for the sexaquark in the hadronic equation of state. It was observed that including the sexaquark as a dark matter candidate in the hadronic matter equation of state, although it has a repulsive interaction with the baryonic matter, softens the equation of state. We assume that the interaction strength of dark matter with baryonic matter increases linearly with the baryon density. We observe that the increase in the effective mass of the Sexaquark as a result of the increase in its vacuum mass causes the equation of state to become stiffer compared to the constant mass state. We determine lower and upper mass limits for this bosonic dark matter based on observational limits for neutron stars in the DD2Y-T model, when a quark-matter phase-to-phase transition is used.

The particle content of dark matter is, for the moment, unknown.
Sexaquarks, as the name indicates, are composite particles made of six quarks-quarks are among the constituents of ``ordinary'' matter. The reason they don't have anything to do with dark matter is that dark matter is made of other kinds of particles. If it were made of known particles, quarks or leptons, it would have had known interactions with ordinary matter, beyond just gravitational interaction (which is how its presence has been established). It doesn't, however, have strong or electromagnetic interactions with ordinary matter (whether it has, only, weak interactions is, still, a matter of study), so it doesn't carry color or electric charge.
How the ``structure of the world was formed'' is known, after the era in which gravity decoupled from the other interactions, in general terms, though many details are, still, not clear. Cf. for instance: https://workshops.ift.uam-csic.es/uploads/charla/275/Zavala_SM_LCDM.pdf
The dark matter phenomena is a result of the incorrect paradigm of non-enforced inertial motion in the modern Physics.
