Warped Extra Dimensions in the Randall-Sundrum Model and a Simple Implementation in Pythia 8

På svenska

Author

  • Jakob Calvén

Summary, in English

We explore the theory and phenomenology of spatial extra dimensions in the Randall-Sundrum scenario; a possible extension to the Standard Model. We motivate the need for beyond standard model extensions and show how the original Randall- Sundrum model solves the hierarchy problem of particle physics. We also treat an extension to the Randall-Sundrum model where Standard Model fields live in the extra- dimensional bulk and see how it predicts resonant production of Kaluza-Klein excitations of the gauge bosons. In particular, we discuss Kaluza-Klein excited gluons and their subsequent decay into tt ̄ pairs. Furthermore, we test an implementation of the Randall- Sundrum model in Pythia 8 and compare the invariant mass of tt ̄ pairs coming from Kaluza-Klein gluons with results in the literature.
