Query: Searching for the Layered Structure of Space at the LHC   Alignment of the main energy fluxes along a straight line in a target plane
has been observed in families of cosmic ray particles detected in the Pamir
mountains. The fraction of events with alignment is statistically significant
for families with superhigh energies and large numbers of hadrons. This can be
interpreted as evidence for coplanar hard-scattering of secondary hadrons
produced in the early stages of the atmospheric cascade development. This
phenomenon can be described within the recently proposed "crystal world," with
latticized and anisotropic spatial dimensions. Planar events are expected to
dominate particle collisions at a hard-scattering energy exceeding the scale
\Lambda_3 at which space transitions from 3D \rightleftharpoons 2D. We study
specific collider signatures that will test this hypothesis. We show that the
energy-spectrum of Drell-Yan scattering and the parton momenta sum rule are
significantly modified in this framework. At the LHC, two jet and three jet
events are necessarily planar, but four jet events can test the hypothesis.
Accordingly, we study in a model-independent way the 5\sigma discovery reach of
the ATLAS and CMS experiments for identifying four jets coplanarities. For the
extreme scenario in which all pp \to 4 jet scattering processes become coplanar
above \Lambda_3, we show that with an integrated luminosity of 10(100) fb^{-1}
the LHC experiments have the potential to discover correlations between jets if
\Lambda_3 \alt 1.25(1.6) TeV.
