In her most recent book, physicist Lisa Randall--Harvard professor, libretto composer, Lego figurine, star in the world of theoretical physics--writes that the universe repeatedly reveals itself ...
Extra dimensions as a source of the electroweak model
Extra dimensions the electroweak model
2010/12/27
The Higgs boson of the Standard model is described by a set of off-diagonal components of the multidimensional metric tensor, as well as the gauge fields. In the low-energy limit, the basic properties...
These lectures on supersymmetry and extra dimensions are aimed at finishing undergraduate and beginning postgraduate students with a background in quantum field theory and group theory. Basic knowledg...
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...

Minimal Universal Extra Dimensions in CalcHEP/CompHEP
minimal universal extra dimensions CalcHEP/CompHEP
2010/3/16
We present an implementation of the model of minimal universal extra dimensions (MUED) in CalcHEP/CompHEP. We include all level-1 and level-2 Kaluza-Klein (KK) particles outside the Higgs sector. The ...
Search for Extra dimensions in a single-jet and missing energy channel at CMS experiment
Extra dimensions missing energy channel single-jet
2010/3/15
A possible solution to the hierarchy problem is the presence of extra spatial dimensions beyond the three ones which are known from our everyday experience. The phenomenological ADD model of large ext...
Einstein-Cartan gravity excludes extra dimensions
Riemann-Cartan weak/Planck hierarchy gravity
2010/3/19
We show that the electron in the Riemann-Cartan spacetime with extra dimensions has a finite size that is much larger than the experimental upper limit on its radius. Thus the Arkani-Hamed-Dimopoulos-...

2010/3/19
We present an overview on the conjectured production of microscopic black holes as a consequence of high energy hadronic collisions at the LHC, CERN (Geneva, Switzerland) from this year on. Provided t...

Need of Dark Energy for Dynamical Compactification of Extra Dimensions on the Brane
Dark Energy Dynamical Compactification the Brane
2010/10/18
We consider a six-dimensional braneworld model and we study the cosmological evolution of a (4+1) braneuniverse. Introducing matter on the brane we show that the scale factor of the physical three-dim...
Generalized Uncertainty Principle, Extra-dimensions and Holography
Generalized Uncertainty Principle Extra-dimensions Holography
2010/10/14
We consider Uncertainty Principles which take into account the role of gravity and the possible existence of extra spatial dimensions. Explicit expressions for such Generalized Uncertainty Principles ...

2010/4/15
Noncommutativity of space coordinates of string theory are reviewed and are related to the large extra dimension solution of the hierarchy problem.
