Elastic collisions in the transplanckian region, where the center-of-mass energy is much larger than the fundamental gravity mass scale, can be described by linearized general relativity and known quantum-mechanical effects as long as the momentum transfer of the process is sufficiently small. For larger momentum transfer, non-linear gravitational effects become important and, although a computation is lacking, black-hole formation is expected to dominate the dynamics. We discuss how elastic… Expand

Transplanckian collisions in TeV scale gravity
Collisions at transplanckian energies offer model independent tests of TeV scale gravity. One spectacular signal is given by black-hole production, though a full calculation of the correspondingExpand
Radiation problem in transplanckian scattering
We investigate hard radiation emission in small-angle transplanckian scattering. We show how to reduce this problem to a quantum field theory computation in a classical background (gravitationalExpand
Including QCD radiation corrections in transplanckian scattering
In the context of Large Extra Dimensions the fundamental Planck scale can be as low as the TeV scale. If this is the way of nature, quantum gravity effects could be visible at the LHC or other HighExpand
Eikonal regime of gravity-induced scattering at higher energy proton colliders
We compute transplanckian parton scattering in flat extra-dimensional theories at the LHC and at the recently discussed high-energy upgrade (HE LHC). We report new leading-order calculations of theExpand

Gravitational scattering in the ADD model at high and low energies
Gravitational scattering in the ADD model is considered at both sub- and transplanckian energies using a common formalism. By keeping a physical cut-off in the KK tower associated with virtual KKExpand

We argue that in the TeV-gravity scenario high energy hadrons colliding on the 3-brane embedded in D = 4+n-dimensional spacetime, with n dimensions smaller than the hadron size, can be considered asExpand
BLACK HOLE PRODUCTION AT THE LARGE HADRON COLLIDER
