Hadronic axion, baryogenesis and dark matter
We investigate the prospects of an extra global symmetry, added to the Standard Model in the context of baryogenesis. The PQ symmetry is studied as an example. We show that the hadronic axion provides a protection of the B-asymmetry even if B − L=0 and that there are no limits on the neutrino masses. It is also shown that there is a crucial difference between the two possible invisible axion mo...
متن کاملAsymmetric Dark Matter and the hadronic spectra of hidden QCD
The idea that dark matter may be a composite state of a hidden nonabelian gauge sector has received great attention in recent years. Frameworks such as asymmetric dark matter motivate the idea that dark matter may have similar mass to the proton, while mirror matter and G × G grand unified theories provide rationales for additional gauge sectors which may have minimal interactions with standard...
متن کاملHadronic uncertainties and isospin violation in supersymmetric dark matter models
Current limits from dark matter direct-detection experiments place a powerful constraint on the parameter space of the Minimal Supersymmetric Standard Model (MSSM). The interpretation of these limits, however, depends sensitively on the hadronic uncertainties associated with the scattering of supersymmetric dark matter particles off nucleons. For spin-independent scattering, we review the role ...
متن کاملAxionic Hot Dark Matter in the Hadronic Axion Window∗
Mixed dark matter scenario can reconcile the COBE data and the observed large scale structure. So far the massive neutrino with a mass of a few eV has been the only discussed candidate for the hot dark matter component. We point out that the hadronic axion in the so-called hadronic axion window, fa ∼ 10 GeV, is a perfect candidate as hot dark matter within the mixed dark matter scenario. The cu...
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...
