Planck scale from top condensation

Planck scale inflationary spectra from quantum gravity

We derive the semiclassical evolution of massless minimally coupled scalar matter in the de Sitter space-time from the Born-Oppenheimer reduction of the Wheeler-DeWitt equation. We show that the dynamics of trans-Planckian modes can be cast in the form of an effective modified dispersion relation and that high energy corrections in the power spectrum of the cosmic microwave background radiation...

Large-scale alignments from WMAP and Planck

We revisit the alignments of the largest structures observed in the cosmic microwave background (CMB) using the seven and nine-yearWilkinson Microwave Anisotropy Probe (WMAP) and first-year Planck data releases. The observed alignments – the quadrupole with the octopole and their joint alignment with the direction of our motion with respect to the CMB (the dipole direction) and the geometry of ...

Supersymmetry : From the Fermi Scale to the Planck Scale 1

The physics of supersymmetry is reviewed from the perspective of physics at ever increasing energies. Starting from the minimal supersymmetric extension of the Standard Model at the electroweak scale, we proceed to higher energies seeking to understand the origin of the many model parameters. Supersymmetric grand unification, supergravity, and superstrings are introduced sequentially, and their...

Top Quark Condensation 1.1 Preliminary

We review a class of dynamical models in which top condensation occurs at the weak scale, giving rise to the large top quark mass and other phenomena. This typically requires a color embedding, SU (3) c → SU (3) 1 × SU (3) 2 , ergo " Topcolor. " Topcolor suggests a novel route to technicolor models in which sequential quarks condense under the Topcolor interaction to break electroweak symmetrie...
