Axino dark matter and baryon number asymmetry from Q-ball decay in gauge mediation
Axino dark matter baryon number asymmetry Q-ball decay gauge mediation
2012/2/21
We investigate the Q-ball decay into the axino dark matter in the gauge-mediated supersymmetry breaking. In our scenario, the Q ball decays mainly into nucleons and partially into axinos to account fo...
Processes taking place in outer space, and not on Earth, are likely to have led to the biological molecules found exclusively in either a left-handed or right-handed form. That is the conclusion drawn...
Testing a prediction of the merger origin of early-type galaxies: a correlation between stellar populations and asymmetry
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/29
One of the key predictions of the merger hypothesis for the origin of early-type (elliptical and lenticular) galaxies is that tidally-induced asymmetric structure should correlate with signatures of a...
Anomalous parity asymmetry of WMAP power spectrum data at low multpoles: is it cosmological or systematics?
parity asymmetry cosmological WMAP power spectrum data
2010/3/8
We have investigated the odd-parity preference of the WMAP 7 year power spectrum. Our investigation shows parity asymmetry of the WMAP data (2<= l <=22) is anomalous at 4-in-1000 level. We also find i...
