Majorana Dark Matter
In this letter in the framework of a simple see-saw scenario with two (or three) quasi degenerate Majorana neutrinos we propose that one of these neutrinos can be very weakly coupled, yet there is a mechanism of the generation of the abundance of such ”dark” neutrino in the early universe. The mechanism of production is due to oscillations between ”dark” Majorana neutrino and one of the Majoran...
متن کاملDark Matter with Dirac and Majorana Gaugino Masses
We consider the minimal supersymmetric extension of the Standard Model allowing both Dirac and Majorana gauginos. The Dirac masses are obtained by pairing up extra chiral multiplets: a singlet S for U(1)Y , a triplet T for SU(2)w and an octet Og for SU(3)c with the respective gauginos. The electroweak symmetry breaking sector is modified by the couplings of the new fields S and T to the Higgs d...
متن کاملSinglet scalar dark matter in noncommutative space
In this paper, we examine the singlet scalar dark matter annihilation to becoming the Standard Model particles in the non-commutative space. In the recent decades, many candidates of dark matter have been offered, but our information about the nature of dark matter is still limited. There are such particle candidates as scalar matetr, fermion, boson, gauge boson, etc.; however, they have nei...
متن کاملEffect of Degenerate Particles on Internal Bremsstrahlung of Majorana Dark Matter
Gamma-rays induced by annihilation or decay of dark matter can be its smoking gun signature. In particular, gamma-rays generated by internal bremsstrahlung of Majorana and real scalar dark matter is promising since it can be a leading emission of sharp gamma-rays. However in the case of Majorana dark matter, its cross section for internal bremsstrahlung cannot be large enough to be observed by ...
متن کاملMajorana and Condensed Matter Physics
1. Spin Response and Universal Connection In [1], Majorana considered the coupling of spins to magnetic fields. The paper is brief, but it contains two ingenious ideas whose importance extends well beyond the immediate problem he treated, and should be part of every physicists’ toolkit. The first of those ideas, is that having solved the problem for spin 12 , one can deduce the solution for gen...
