Dimensional reduction of the massless limit of the linearized "New Massive Gravity"

H. A. Biazotti, D. Dalmazi, G. B. de Gracia

The so called "New Massive Gravity" in $D=2+1$ consists of the Einstein-Hilbert action (with minus sign) plus a quadratic term in curvatures ($K$-term). Here we perform the Kaluza-…
