DUSEL Theory White Paper
S. Raby, T. Walker, K. S. Babu +28
The NSF has chosen the site for the Deep Underground Science and Engineering Laboratory (DUSEL) to be in Lead, South Dakota. In fact, the state of South Dakota has already stepped…
Cosmological bounds on the "millicharges" of mirror particles
Zurab Berezhiani, Angela Lepidi
Mirror world, a parallel hidden sector with microphysics identical to ordinary particle physics, can have several interesting phenomenological and astrophysical implications and mi…
Spontaneous Breaking of Lorentz-Invariance and Gravitons as Goldstone Particles
Z. Berezhiani, O. V. Kancheli
We consider some aspects of spontaneous breaking of Lorentz Invariance in field theories, discussing the possibility that the certain tensor operators may condensate in the ground…
More about neutron - mirror neutron oscillation
Zurab Berezhiani
It was pointed out recently that oscillation of the neutron into mirror neutron , a sterile twin of the neutron with exactly the same mass, could be a very fast process wit…
Exact Spherically Symmetric Solutions in Massive Gravity
Z. Berezhiani, D. Comelli, F. Nesti +1
A phase of massive gravity free from pathologies can be obtained by coupling the metric to an additional spin-two field. We study the gravitational field produced by a static spher…
