Mixed dark matter in Universal Extra Dimension models with. A bstract. It is well known that R-symmetric models dramatically alleviate the SUSY flavor and CP problems. We study particular modifications of existing R-symmetric models which share the solution to the above problems, and have interesting consequences for electroweak baryogenesis and the Dark Matter (DM) content of the universe., dark energy is 75%, and the ratio of dark matter to baryonic matter is 5 to 1. In the zero-energy universe hypothesis, the total amount of energy in the universe is exactly zero..

Electroweak WIMPs are under intense scrutiny from direct detection, indirect detection, and collider experiments. Nonetheless the pure (pseudo-Dirac) higgsino, one of the simplest such WIMPs, remains elusive. We present an up-to-date assessment of current experimental constraints on neutralino dark matter. The strongest bound on pure higgsino The lightest combination of them provides a viable thermal dark matter if the Higgsino mass scale is close to $1$ TeV. The small mass splitting induced by singlino turns the neutral components of Higgsinos into pseudo-Dirac fermions which successfully evade the constraints from the direct detection experiments if the singlino mass is $\lesssim 10^8$ GeV. We analyse the constraints on …

In theoretical physics, negative mass is matter whose mass is of opposite sign to the mass of normal matter, e.g. в€’1 kg. [1] [2] Such matter would violate one or more energy conditions and show some strange properties, stemming from the ambiguity as to whether attraction should refer to force or the oppositely oriented acceleration for negative mass.

The first KK particle of the right-handed neutrino is a candidate for dark matter in this framework, and its relic abundance is determined by three processes, (1) the decay of the KK photon into the first KK right-handed neutrino in the late universe, (2) production of the first KK right-handed neutrino from the thermal bath in the early universe, and (3) the decay of higher KK right-handed 2 Dark Matter Searches Different approaches needed to discover the exact nature of particle DM Moriond Cosmology 2018 March 17-24, 2018

We take the dark matter to be a pseudo-Dirac fermion charged under a dark U(1). At high energies, where the U(1) symmetry is unbroken, the dark matter is a charged Dirac fermion; at low energies, a small Majorana mass splits the Dirac fermion into two nearly-degenerate Majorana states Лњ 1 and Лњ 2. Since these states cannot carry conserved charge, their couplings with the U(1) vector boson A We study the pseudo-Dirac mixing of left and right-handed neutrinos in the case where the Majorana masses M_L and M_R are small when compared with the Dirac...
