Black hole bound on the number of species and quantum gravity at CERN LHC
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 ...
2008Gravity 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 ...
2008Oversampled Time Estimation Techniques for Precision Photonic Detectors
Several physical quantities of interest are of quantum nature, often measurable as distinct particles. Light is one such example, photons being its particles. In conventional detectors, light is converted onto electrical charges and hence onto a current or ...
