Symmetries make the world go round, but so do asymmetries. A case in point is an asymmetry known as charge–parity (CP) asymmetry, which is required to explain why matter vastly outnumbers antimatter i...
CP asymmetry is the only non-trivial difference between matter and antimatter found so far. Its discovery in neutral kaon decays in 1964 came as a big surprise to the physics community, but today it i...
Low Mass Gluino within the Sparticle Landscape, Implications for Dark Matter, and Early Discovery Prospects at LHC-7
Low Mass Gluino Sparticle Landscape Dark Matter
2010/12/24
We analyze supergravity models that predict a low mass gluino within the landscape of sparticle mass hierarchies. The analysis includes a broad class of models that arise in minimal and in non-minimal...
Can the matter-antimatter asymmetry be easier to understand within the "spin-charge-family-theory", predicting twice four families and two times $SU(2)$ vector gauge and scalar fields?
the matter-antimatter asymmetry spin-charge-family-theory
2010/12/27
This contribution is an attempt to try to understand the matter-antimatter asymmetry in the universe within the {\it spin-charge-family-theory} if assuming that transitions in non equilibrium processe...
Background independent condensed matter models for quantum gravity
Background independent condensed matter models quantum gravity
2010/12/27
A number of recent proposals for a quantum theory of gravity are based on the idea that spacetime geometry and gravity are derivative concepts and only apply at an approximate level. There are two fu...
We consider new signatures of WIMPless dark matter, particularly those which can be used to test models with low dark matter mass. We focus on detection prospects at hadron colliders through the prod...
Black-Hole Solutions to Einstein's Equations in the Presence of Matter and Modifications of Gravitation in Extra Dimensions
Black-Hole Solutions Einstein's Equations Modifications
2010/12/24
In this thesis, we wish to examine the black-hole solutions of modified gravity theories inspired by String Theory or Cosmology. Namely, these modifications will take the guise of additional gauge and...
Dilaton stabilization by massive fermion matter
Dilaton stabilization massive fermion matter
2010/12/24
The implications for the Dilaton stabilization problem are investigated when the effective potential for this field is generated by the existence of a massive fermion. The previously evaluated two lo...
Production of matter in the universe via after-GUT interaction
Production of matter universe via after-GUT interaction
2010/12/21
In this paper we propose a model of the dark energy decay into ordinary and dark matter via the action of some interaction, dubbed as the after-GUT interaction, with the mass scale between the electro...
First Results of the Phase II SIMPLE Dark Matter Search
SIMPLE Dark Matter Search superheated droplet detectors
2010/3/16
We report results of a 14 kgd SIMPLE run with 15 superheated droplet detectors of total active mass 0.209 kg, comprising the first stage of a 30 kgd Phase II measurement. In combination with the resul...
Dark Matter Candidates from Particle Physics and Methods of Detection
Dark Matter Particle Physics
2010/3/16
The identity of dark matter is a question of central importance in both astrophysics and particle physics. In the past, the leading particle candidates were cold and collisionless, and typically predi...
Dark Matter-Motivated Searches for Exotic 4th Generation Quarks in Tevatron and Early LHC Data
Exotic 4th Generation Quarks Early LHC Data
2010/3/16
We determine the prospects for finding dark matter at the Tevatron and LHC through the production of exotic 4th generation quarks T' that decay through T' \to t X, where X is dark matter. The resultin...

Nuclear Matter Hyperon-Rich Neutron Stars Density-Dependent
2009/9/4
The conserving σ-ω-ρ mean-field approximation with nonlinear interactions of hadrons has been applied to examine properties of nuclear matter and hyperonic neutron stars. The nonlinear interactions th...
Antikaon condensation in neutron star matter with strong magnetic fields

2009/8/17
We study the influence of strong magnetic fields on antikaon condensation in neutron star matter using the quark-meson coupling (QMC) model. The QMC model describes a nuclear many-body system as nonov...
