Transplanckian Collisions at the LHC and Beyond
Gian F. Giudice, Riccardo Rattazzi, James D. Wells
Elastic collisions in the transplanckian region, where the center-of-mass energy is much larger than the fundamental gravity mass scale, can be described by linearized general rela…
Cosmic Rays as Probes of Large Extra Dimensions and TeV Gravity
Roberto Emparan, Manuel Masip, Riccardo Rattazzi
If there are large extra dimensions and the fundamental Planck scale is at the TeV scale, then the question arises of whether ultra-high energy cosmic rays might probe them. We stu…
Running and Matching from 5 to 4 Dimensions
R. Contino, L. Pilo, R. Rattazzi +1
We study 5 dimensional grand-unified theories in an orbifold geometry by the method of effective field theory: we match the low and high energy theories by integrating out at 1-loo…
Holography and the Electroweak Phase Transition
Paolo Creminelli, Alberto Nicolis, Riccardo Rattazzi
We study through holography the compact Randall-Sundrum (RS) model at finite temperature. In the presence of radius stabilization, the system is described at low enough temperature…
