What is the gamma gamma resonance at 750 GeV?

Riccardo Rattazzi, Francesco Riva, Roberto Franceschini, Michele Redi, Riccardo Torre

Run 2 LHC data show hints of a new resonance in the diphoton distribution at an invariant mass of 750 GeV. We analyse the data in terms of a new boson, extracting information on its properties and exploring theoretical interpretations. Scenarios covered in ...

AdS/QCD: the relevance of the geometry

Andrea Wulzer, Michele Redi, Diego Becciolini

We investigate the relevance of the metric and of the geometry in five-dimensional models of hadrons. Generically, the metric does not affect strongly the results and even flat space agrees reasonably well with the data. Nevertheless, we observe a preferen ...

Phenomenology of 10(32) dark sectors

Michele Redi

We postulate an exact permutation symmetry acting on 10(32) standard model copies as the largest possible symmetry extension of the standard model. This setup automatically lowers the fundamental gravity cutoff down to TeV, and thus, accounts for the quant ...

Gravity Cutoff in Theories with Large Discrete Symmetries

Sergey Sibiryakov, Michele Redi

We set an upper bound on the gravitational cutoff in theories with exact quantum numbers of large N periodicity, such as Z(N) discrete symmetries. The bound stems from black hole physics. It is similar to the bound appearing in theories with N particle spe ...

Black hole bound on the number of species and quantum gravity at CERN LHC

Michele Redi

In theories with a large number N of particle species, black hole physics imposes an upper bound on the mass of the species equal to M-Planck/root N. This bound suggests a novel solution to the hierarchy problem in which there are N approximate to 10(32) g ...

Cascading gravity: Extending the Dvali-Gabadadze-Porrati model to higher dimension

Michele Redi

We present a generalization of the Dvali-Gabadadze-Porrati scenario to higher codimensions which, unlike previous attempts, is free of ghost instabilities. The 4D propagator is made regular by embedding our visible 3-brane within a 4-brane, each with their ...

Non-Pauli-Fierz Massive Gravitons

Michele Redi

We study general Lorentz invariant theories of massive gravitons. We show that, contrary to the standard lore, there exist consistent theories where the graviton mass term violates Pauli-Fierz structure. For theories where the graviton is a resonance, this ...
