Anomalous parity asymmetry of WMAP power spectrum data at low multpoles: is it cosmological or systematics?
parity asymmetry cosmological WMAP power spectrum data
font style='font-size:12px;'>
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...
Left-right asymmetry for meson production in SIDIS process
semi-inclusive deep inelastic scattering transversity left-right asymmetry

2008/12/12
Multi-filter Rotating Shadowband Radiometers (MFRSRs) provide routine measurements of the aerosol optical depth (τ) at six wavelengths (0.415, 0.5, 0.615, 0.673, 0.870 and 0.94 μm). The single-scatter...

2008/12/12
One of the striking features of tropical instability waves (TIWs) is that they appear to be more prominent north of the equator. A linearized, 2½-layer ocean model is used to investigate effect...
