Electroweak vacuum decay in metric-affine gravity
Ioannis D. Gialamas, Hardi Veermäe
We investigate the stability of the electroweak vacuum in metric-affine gravity in which the Standard Model Higgs boson can be non-minimally coupled to both the Ricci scalar and th…
New infra-red enhancements in 4-derivative gravity
Alberto Salvio, Alessandro Strumia, Hardi Veermae
4-derivative gravity provides a renormalizable theory of quantum gravity at the price of introducing a physical ghost, which could admit a sensible positive-energy quantization. To…
On the Quantisation of Complex Higher Derivative Theories and Avoiding the Ostrogradsky Ghost
Martti Raidal, Hardi Veermäe
Generic higher derivative theories are believed to be fundamentally unphysical because they contain Ostrogradsky ghosts. We show that within complex classical mechanics it is possi…
Heavy spin-2 Dark Matter
Eugeny Babichev, Luca Marzola, Martti Raidal +4
We provide further details on a recent proposal addressing the nature of the dark sectors in cosmology and demonstrate that all current observations related to Dark Matter can be e…
