Einstein-Cartan Portal to Dark Matter
Mikhail Shaposhnikov, Andrey Shkerin, Inar Timiryasov +1
It is well-known since the works of Utiyama and Kibble that the gravitational force can be obtained by gauging the Poincaré group, which puts gravity on the same footing as the Sta…
Einstein-Cartan gravity, matter, and scale-invariant generalization
Mikhail Shaposhnikov, Andrey Shkerin, Inar Timiryasov +1
We study gravity coupled to scalar and fermion fields in the Einstein-Cartan framework. We discuss the most general form of the action that contains terms of mass dimension not big…
Higgs inflation in Einstein-Cartan gravity
Mikhail Shaposhnikov, Andrey Shkerin, Inar Timiryasov +1
We study inflation driven by the Higgs field in the Einstein-Cartan formulation of gravity. In this theory, the presence of the Holst and Nieh-Yan terms with the Higgs field non-mi…
Unveiling complex vector dark matter by magnetic field
Emin Nugaev, Andrey Shkerin
We discuss the possibility that dark matter is made of a new complex massive vector field with a global -symmetry. The field interacts with the Standard Model via coupling to…
Quantum Effects in Palatini Higgs Inflation
Mikhail Shaposhnikov, Andrey Shkerin, Sebastian Zell
We study quantum effects in Higgs inflation in the Palatini formulation of gravity, in which the metric and connection are treated as independent variables. We exploit the fact tha…
Standard Model Meets Gravity: Electroweak Symmetry Breaking and Inflation
Mikhail Shaposhnikov, Andrey Shkerin, Sebastian Zell
We propose a model for combining the Standard Model (SM) with gravity. It relies on a non-minimal coupling of the Higgs field to the Ricci scalar and on the Palatini formulation of…
