From k-essence to generalised Galileons
Cédric Deffayet, Xian Gao, Daniele A. Steer +1
We determine the most general scalar field theories which have an action that depends on derivatives of order two or less, and have equations of motion that stay second order and l…

Non linear Fierz-Pauli theory from torsion and bigravity
Cédric Deffayet, Seifallah Randjbar-Daemi
The non linear aspects of a recently proposed model of massive spin-2 particles with propagating torsion are studied. We obtain a nonlinear equation which reduces at linear order t…
