Hypothetical particles called axions could solve two enigmas at once. They could account for dark matter, the mysterious substance that is thought to make up most of the matter in the Universe, and th...
New stationary solutions of four-dimensional dilaton-axion gravity are presented, which correspond to the charged Taub-NUT and Israel-Wilson-Perjés (IWP) solutions of Einstein-Maxwell theory. The char...
The standard axion-like particle explanation of the observed large-scale coherent orientations of quasar polarisation vectors is ruled out by the recent measurements of vanishing of circular polarisat...
The inflationary paradigm has enjoyed phenomenological success, however, a compelling particle physics realization is still lacking. The key obstruction is that the requirement of a suitably flat scal...

Intense electric field  1010− 1011 V/cm in crystal has been known for a long time and has wide applications.
Supersymmetric grand unified theories based on the gauge group SO(10) are highly motivated. In the simplest models, one expects t-b-\tau Yukawa coupling unification, in addition to gauge, matter and H...
Dark matter is a focused issue in galactic evolution and cosmology. Axion is a viable particle candidate for dark matter. Its interaction with photon is an effective way to detect it, e.g., pseudoscal...
This paper discusses a new type of thin-shell wormhole constructed by applying the cut-and-paste technique to two copies of a charged black hole in generalized dilaton-axion gravity, which was inspire...
2007Vol.47No.4pp.665-668DOI: Absorption Cross Section of Static Einstein-Maxwell Dilation Axion Black Hole for Scalar Particles LIU Chang-Qing and JING Ji-Liang Institut...
The thermodynamics of a stationary axisymmetric Einstein-Maxwell dilatom-axion (EMDA) black hole is investigated using general statistical physics methods. It is shown that entropy and energy have the...
The sensitivity of c\rightarrow u g decay in the recently proposed gluino-axion model is analyzed for a light sbottom in a restricted parameter space. The decay rate enhances up to 3% with respect to ...
