where T I1N is the higher dimensional energy-momentum tensor. The interaction of the
graviton with the graviton KK states and with the SM fields are obtained by integrating
the action over the extra coordinates. Because all these states are coupled with the
universal strength I/Mp1 this leads to the compelling possibility of the control of the size
of the extra dimensions by processes at energies that will be accessible via the particle
accelerators of the near future. Although the coupling is extremely small, the effective
coupling is enhanced by the large number of KK states.
Referring to Figure 7, additional energy in the form of matter or radiation with the TeV
energy scale can alter the shape of the effective potential. In particular, the extrema
determining the size of the extra dimensions are modified with the change of the
Casimir energy density and hence, the dark energy density, in the models under
consideration.
In the ADD model discussed in Section 5.2, the Standard Model fields are confined to a
4-dimensional brane and a new gravity scale M /) = c 2-I) > > TeV is introduced in the D
= 4 + d dimensions, where dis the number of extra dimensions. This is determined
quite easily by forming the higher dimensional action and integrating out the extra
dimension.
The Atlas experiment at CERN's Large Hadron Collider will have the capability to probe
the ADD type extra dimensions up to Mo~ 8 TeV. In the Randall Sundrum scenario, the
hierarchy is explained by the warp factor in the AdSS bulk geometry. A lower bound can
be placed on the lowest KK mass by electroweak precision tests (masses on the order
of 1 TeV are allowed). In the Universal Extra Dimension scenario, Tevatron results
constrain the compactification scale to Mc > 400 GeV. Because the Atlas experiment
will be sensitive to Mc - 3 TeV , the estimates in this section indicate that if nature is in
fact described by one of these higher dimensional scenarios, then the additional
dimensions can be probed.
Even more exciting is the possibility that their size may be controlled at the energies
accessible to the Large Hadron Collider. When the Casimir energy to play the role of
dark energy is involved, one can see that the possibility for the direct control of the
local dark energy density by controlling the size of the additional dimensions is possible.
8. Summary
The idea that a sufficiently advanced technology may interact with, and acquire direct
control over, the higher dimensions is a tantalizing possibility, and one that is most
certainly worthy of deeper investigation. Control of this higher dimensional space may
be a source of technological control over the dark energy density and could ultimately
play a role in the development of exotic propulsion technologies; specifically, a warp
drive.
Of course, this may not be actualized until many years in the future, but consider the
many spectacular physical phenomena that are believed to be true at this early point in
