Abstract: We study the possibility that Dark Matter (DM) is made of Feebly Interacting Massive Particles (FIMP) interacting just gravitationally with the Standard Model particles in the framework of a Clockwork/Linear Dilaton (CW/LD) model. We restrict… read more here.

Abstract: Abstract We consider the most general Kaluza-Klein (KK) compactification on S1/ℤ2 of a five dimensional (5D) graviton-dilaton system, with a non-vanishing dilaton background varying linearly along the fifth dimension. We show that this background produces… read more here.

DOI: 10.1134/s1547477120050271
Abstract: In this talk we review the minimal embedding in $$\mathcal{N} = 2$$ , $$D = 5$$ supergravity of a five–dimensional dilaton–gravity theory that serves as a toy model for the holographic dual of six–dimensional little… read more here.

DOI: 10.1142/s0217751x23500653
Abstract: Using the ambitwistor string theory, we study graviton scattering amplitudes in a light-like linear dilaton background of ten-dimensional supergravity. At the tree level, we find that the three-graviton amplitude coincides with the type II superstring… read more here.
