A facility to search for hidden particles at the CERN SPS: the SHiP physics case.

Sergey Alekhin, +95 more
- 24 Oct 2016 - 
TL;DR: It is demonstrated that the SHiP experiment has a unique potential to discover new physics and can directly probe a number of solutions of beyond the standard model puzzles, such as neutrino masses, baryon asymmetry of the Universe, dark matter, and inflation.

CP properties of symmetry-constrained two-Higgs-doublet models

Pedro M. Ferreira, +5 more
- 27 Aug 2010 - 
TL;DR: In this paper, the authors studied the CP properties of all cases in the bilinear formalism and showed that soft breaking of the symmetry can lead to spontaneous CP violation in three of the classes.

Lee–Wick theories at high temperature

Bartosz Fornal, +2 more
- 27 Apr 2009 - 
TL;DR: In this paper, the authors examined the behavior of Lee-Wick resonances at high temperature and showed that they contribute negatively to the energy density ρ and pressure p and at temperatures much greater than their mass M their O(T^4) contributions to ρ cancel against those of the ordinary (light) particles.
