14 Apr 2010 | | Abstract: | The feasibility for the observation of a certain leptonic Kaluza-Klein (KK)
hard process in {em pp} interactions at the LHC is presented. Within the
$S^1/Z_2$ TeV$^{-1}$ extra dimensional theoretical framework with the focus on
the KK excitations of the Standard Model $gamma$ and $Z^0$ gauge bosons, the
hard-process, $far f o sum_n(gamma^*/Z^* o)_n o F ar F$, has been
used where $f$ is the initial state parton, $F$ the final state lepton and
$(gamma^*/Z^* o)_{n}$ is the $n^{
m th}$ KK excitation of the $gamma/Z^0$
boson. For this study the analytic form for the hard process cross section has
been independently calculated and has been implemented using the {sc Moses}
framework. The Moses framework itself has been used as an external process
within the {sc Pythia}8 Monte Carlo generator which provides the phase space
generation for the final state leptons and partons from the initial state
hadrons, and the simulation of initial and final state radiation and
hadronization. A brief discussion of the possibility for observing and
identifying the unique signature of the KK signal given the current LHC program
is also presented. | | Source: | arXiv, 1004.2432 | | Services: | Forum | Review | PDF | Favorites | |
