Within the scenario of large extra dimensions, the Planck scale is lowered to values soon accessible. Among the predicted effects, the production of TeV mass black holes at the LHC is one of the mostâ€¦ (More)

We show that models with deformations of special relativity that have an energy-dependent speed of light have nonlocal effects. The requirement that the arising nonlocality is not in conflict withâ€¦ (More)

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 ofâ€¦ (More)

We review the question of whether the fundamental laws of nature limit our ability to probe arbitrarily short distances. First, we examine what insights can be gained from thought experiments forâ€¦ (More)

In models with large additional dimensions, the GUT scale can be lowered to values accessible by future colliders. Due to modification of the loop corrections from particles propagating into theâ€¦ (More)

We investigate how deformations of special relativity in mo mentum space can be extended to position space in a consistent way, such that t he dimensionless contraction between wave-vector andâ€¦ (More)

The aim of this paper is to clarify the relation between three different approaches of theories with a minimal length scale: A modification of the Lorentzgroup in the â€™Deformed Special Relativityâ€™,â€¦ (More)

Planck scale physics represents a future challenge, locate d between particle physics and general relativity. The Planck scale marks a threshold b eyond which the old description of spacetime breaksâ€¦ (More)
