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...
Supersymmetry and stationary solutions in dilaton-axion gravity
Gravity is fixed charged Taub - the NUT steel pipe concrete the construction
2014/12/23
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...
Can axion-like particles explain the alignments of the polarisations of light from quasars?
axion-like particles explain alignments polarisations
2011/9/30
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.
SO(10) SUSY GUTs with mainly axion cold dark matter: implications for cosmology and colliders
Supersymmetry Grand unified theories axions
2010/3/16
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...
Axion Search with Q;A Experiment
Dark matter pseudoscalar-photon interaction axion vacuum dichroism vac-uum birefringence Q & A experiment
2010/3/15
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...

Thermodynamics of stationary axisymmetric Einstein-Maxwell dilaton-axion black hole
Thermodynamics black hole
2007/7/19
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 Gluino-Axion Model
c\rightarrow u g Gluino-Axion Model
2010/4/13
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 ...
