Abstract. We review proposals of brane world models which attempt to combine gauge theories with gravity at TeV scale by confining the gauge theory to a three-brane embedded in higher dimensional bulk. Gravity, however, propagates in the directions transverse to the brane as well.

Keywords. Randall--Sundrum model; string theory.
