Why is dark matter considered a particle? What properties does a particle have?

Particles have mass, measurable energy output, and empirical evidence.

If Dark matter is a string than it must be a higher vibrating string.

It's not considered to be a particle, per se. Strictly speaking, it's a phenomena for which no explentation currently exists.

If it's a field of force, like some sort of meta-gravity, then, like all fields of force, there's supposed to be an associated "particle of exchange" encapsulating the properties - like charge, mass, momentum, etc. - that are being passed from one body to another via that field of force, so if there's a dark-matter field, then there's a dark-matter particle of exchange.

• Will you position change if the super collider creates a hadron?

Why do you think Dark Matter is not a high vibrating string according to string theory? String theory would explain the anti-gravity properties observed by dark matter.

String theory likewise can be used to predict the existence of black holes.

Is string theory the grand unifying theory of everything?

Maybe it would be if it could produce a single testable experiment, but it hasn't, so for now, string theory is still in the realms of being a vast mathematic model, which means I don't give it any more credence that a religion.

String theory maybe verified with the super collider, if they can keep mechanical and human error from preventing the experiment.

Science often is unprovable at first. The theory of relativity was proven by the bending of light around the sun, as predicted by Einstein. The theory was credible, long before, evidence was capable of proving it valid.
