-<h2>Extra-Dimensional Processes</h2>
-
-Scenarios with extra dimensions (ED) allow a multitude of processes.
-Currently three different categories of processes are implemented.
-The first involves the production of excited Kaluza Klein states
-within so-called Randall-Sundrum (RS) scenarios, the second is
-related to resonance production in TeV-1 sized extra dimensions
-and the third relates to phenomena from large extra dimensions (LED).
-Due to the close relation between the LED model and a so-called
-unparticle model, similar unparticle processes are also kept in this
-section.
-
-<h3>Randall-Sundrum Resonances, production processes</h3>
-
-The graviton (G*) and gluon (KKgluon*) resonance states are assigned
-PDG code 5100039 and 5100021 respectively. The G* processes are
-described in <ref>Bij01</ref> and the KKgluon* process in <ref>Ask11</ref>.
-Decays into fermion and boson pairs are handled with the correct
-angular distributions, while subsequent decays are handled
-isotropically.
-
-<p/>
-There are two lowest-order processes that together normally
-should be sufficient for a simulation of <ei>G^*</ei> production.
-
-<flag name="ExtraDimensionsG*:all" default="off">
-Common switch for the group of lowest-order <ei>G^*</ei> production

-In addition there are three first-order processes included. These
-are of less interest, but can be used for dedicated studies of the
-high-<ei>pT</ei> tail of <ei>G^*</ei> production. As usual, it would
-be double counting to include the lowest-order and first-order
-processes simultaneously. Therefore the latter ones are not included
-with the <code>ExtraDimensionsG*:all = on</code> option. In this set
-of processes all decay angles are assumed isotropic.

-<h3>Randall-Sundrum Resonances, parameters</h3>
-
-In the above scenario the main free parameters are the masses, which
-are set as usual. In addition there are the following coupling parameters.
-The coupling <ei>kappaMG</ei> follows the conventions in <ref>Bij01</ref>,
-where as the flavour dependent couplings follow the conventions used in
-<ref>Dav01</ref>.

-<flag name="ExtraDimensionsG*:SMinBulk" default="off">

-This parameter is only relevant for the lowest-order graviton
-(<ei>G*</ei>) processes, where as the first-order processes
-corresponds to the <ei>off</ei> scenario.

-<h3>Large Extra Dimensions, production processes</h3>
-
-The LED graviton, where the KK-modes normally are summed and do not
-give rise to phenomena individually, is assigned PDG code 5000039.
-The graviton emission and virtual graviton exchange processes use
-the same implementation as the corresponding unparticle processes,
-which are all described in <ref>Ask10</ref>. It is also possible to
-generate monojet events from scalar graviton emission as described
-in <ref>Azu05</ref>, by turning on the option <ei>GravScalar</ei>.
-
-<p/>
-<ei>Note:</ei> As discussed in <ref>Ask09</ref>, for the graviton or
-unparticle emission processes the underlying Breit-Wigner mass
-distribution should be matched to the graviton mass spectrum in order
-to achieve an optimal MC efficiency.
