The search for decaying Dark Matter
J. W. den Herder, A. Boyarsky, O. Ruchayskiy +15
We propose an X-ray mission called Xenia to search for decaying superweakly interacting Dark Matter particles (super-WIMP) with a mass in the keV range. The mission and its observa…
Quantum scale-invariant models as effective field theories
M. E. Shaposhnikov, F. V. Tkachov
We address the question of whether the quantum scale-invariant theories introduced in [1] are renormalizable or play the role of effective field theories that are valid below the P…
Quantum scale invariance, cosmological constant and hierarchy problem
Mikhail Shaposhnikov, Daniel Zenhausern
We construct a class of theories which are scale invariant on quantum level in all orders of perturbation theory. In a subclass of these models scale invariance is spontaneously br…
Scale invariance, unimodular gravity and dark energy
Mikhail Shaposhnikov, Daniel Zenhausern
We demonstrate that the combination of the ideas of unimodular gravity, scale invariance, and the existence of an exactly massless dilaton leads to the evolution of the universe su…
How to find neutral leptons of the nuMSM?
Dmitry Gorbunov, Mikhail Shaposhnikov
An extension of the Standard Model by three singlet fermions with masses smaller than the electroweak scale allows to explain simultaneously neutrino oscillations, dark matter and…
