Query: Static Black Holes of Metric-Affine Gravity in the Presence of Matter   We investigate spherically symmetric and static gravitational fields
representing black hole configurations in the framework of metric-affine gauge
theories of gravity (MAG) in the presence of different matter fields. It is
shown that in the triplet ansatz sector of MAG, black hole configurations in
the presence of non-Abelian matter fields allow the existence of black hole
hair. We analyze several cases of matter fields characterized by the presence
of hair and for all of them we show the validity of the no short hair
conjecture.
