Effective field theory for hydrodynamics: Wess-Zumino term and anomalies in two spacetime dimensions
Effective field theory hydrodynamics:anomalies spacetime dimensions
2011/10/14
We develop the formalism that incorporates quantum anomalies in the effective field theory of non-dissipative fluids. We consider the effect of adding a Wess-Zumino-like term to the low-energy effecti...
Large-angle correlation anomalies and odd-parity preference in CMB data
cosmic background radiation early universe methods: data analysis meth-ods: statistical
2010/11/9
Angular power spectrum of CMB anisotropy and two point angular point correlation possess some
equivalence. Noting this, we have investigated the association between the WMAP large-angle corre-lation ...
Abundance anomalies in pre-main-sequence stars: Stellar evolution models with mass loss
Diffusion — stars chemically peculiar — stars mass–loss — stars pre–main-sequence — stars evolution — stars
2010/11/12
Aims. The effects of atomic diffusion on internal and surface abundances of A and F pre–main-sequence stars with mass loss are studied in order to determine at what age the effects materialize, as wel...
Can past gamma-ray bursts explain both INTEGRAL and PAMELA/Fermi anomalies simultaneously?
Gamma ray bursts gamma-ray bursts
2010/3/9
Gamma-ray bursts (GRB) have been invoked to explain both the 511 keV emission from the galactic bulge and the high-energy positron excess inferred from the PAMELA and Fermi data. While independent exp...
