Higher-derivative massive actions from dimensional reduction [PDF]
Euihun Joung, Karapet MkrtchyanA procedure to obtain higher-derivative free massive actions is proposed. It consists in dimensional reduction of conventional two-derivative massless actions, where solutions to constraints bring in higher derivatives. We apply this procedure to derive the arbitrary dimensional generalizations of (linearized) New Massive Gravity and New Topologically Massive Gravity.View original: http://arxiv.org/abs/1212.5919
