Large Extra Dimensions and the Minimal Length
Large extra dimensions lower the Planck scale to values soon accessible. Motivated by String Theory, the models of large extra dimensions predict a vast number of new effects in the energy range of the lowered Planck scale, among them the production of TeV-mass black holes and gravitons. But not only is the Planck scale the energy scale at which effects of modified gravity become important. Str...
متن کاملThe Minimal Length and Large Extra Dimensions
Planck scale physics represents a future challenge, located between particle physics and general relativity. The Planck scale marks a threshold beyond which the old description of spacetime breaks down and conceptually new phenomena must appear. Little is known about the fundamental theory valid at Planckian energies, except that it necessarily seems to imply the occurrence of a minimal length ...
متن کاملMinimal Universal Extra Dimensions
Highly degenerate spectra associated with universal extra dimensions (UED) provide an interesting phenomenology not only from the point of view of cosmology and astrophysics, but also for colliders. We study these exotic signals for the simplest case, called minimal UED, where it is natural to find slow charged particles, displaced vertices, tracks with non-vanishing impact parameters, track ki...
متن کاملLarge hierarchy from extra dimensions
We argue that the familiar gauge hierarchy between the fundamental Planck scale MP l and the electroweak scaleMW , can be naturally explained in higher dimensional theories with relatively large radii (Rc > 1/MP l) extra dimensions. In particular, we show that it is possible that the electroweak Higgs mass at high energies is of the order of MP l, but radiative corrections drive it to an infrar...
متن کاملNeutrino oscillations and large extra dimensions
Assuming that right-handed neutrinos exist and propagate in some large extra dimensions, we attempt to give a comprehensive description of the phenomenology of neutrino oscillations. A few alternative explanations of the atmospheric neutrino anomaly emerge, different from the standard νμ → ντ or νμ → νsterile interpretations. Constraints from nucleosynthesis and supernova 1987a are discussed. T...
