I review the current status of phenomenological programs inspired by quantum-spacetime
research. I stress in particular the significance of results establishing that certain data …

The breaking of electroweak symmetry, and origin of the associated “weak scale”, v weak=
1/2 2 GF= 175 GeV, may be due to a new strong interaction. Theoretical developments over …

This document proposes a collection of simplified models relevant to the design of new-
physics searches at the Large Hadron Collider (LHC) and the characterization of their …

Recently, a new framework for solving the hierarchy problem has been proposed which
does not rely on low energy supersymmetry or technicolor. The gravitational and gauge …

We recently proposed a solution to the hierarchy problem not relying on low-energy
supersymmetry or technicolor. Instead, the problem is nullified by bringing quantum gravity …

We show that in a general hidden sector model, supersymmetry breaking necessarily
generates at one loop a scalar and gaugino mass as a consequence of the super-Weyl …

We show that the bound from the electroweak data on the size of extra dimensions
accessible to all the standard model fields is rather loose. These “universal” extra …

We consider the novel Kaluza-Klein (KK) scenario where gravity propagates in the (4+ n)-
dimensional bulk of spacetime, while gauge and matter fields are confined to the (3+ 1) …

Recently it has been pointed out that the characteristic quantum-gravity scale could be as
low as the weak scale in theories with gravity propagating in higher dimensions. The …

We present a novel inflationary scenario in theories with low scale (TeV) quantum gravity, in
which the standard model particles are localized on the branes whereas gravity propagates …
