On anomalies in effective models with nonlinear symmetry realization
Andrej Arbuzov, Boris Latosh
Anomalous features of models with nonlinear symmetry realization are addressed. It is shown that such models can have anomalous amplitudes breaking of its original symmetry realiza…
Effective Potential of Scalar-Tensor Gravity
Andrej Arbuzov, Boris Latosh
Effective potential of a scalar field induced by weak gravity is studied. The set of operators relevant for leading effects and preserving the second order of field equations is fo…
Graviton Mixing
Boris Latosh
Mechanism mixing graviton spin states is defined. The mixing appears naturally due to loop corrections. Its influence on amplitudes involving matter states is shown, implications f…
One-loop effective scalar-tensor gravity
Boris Latosh
Non-minimal interactions are proven to be generated at the one-loop level in simple scalar-tensor gravity models. The John interaction from the Fab Four class is generated. The int…
Basic issues of conservative approaches to quantum theory of gravity
Boris Latosh
Review of the most basic issues appearing in the most conservative approaches to quantum theory of gravity is given. The most part of the review is devoted to issues of perturbativ…
The Spectrum of Quantum Gravity
Xavier Calmet, Boris Latosh
In this paper we consider the degrees of freedom beyond the graviton present in the effective field theory for quantum gravity. We point out that the position of the poles due to $…
