Discerning secluded sector gauge structures

Carloni, Lisa LU ; Rathsman, Johan LU and Sjöstrand, Torbjörn LU (2011) In Journal of High Energy Physics
Abstract
New fundamental particles, charged under new gauge groups and only weakly coupled to the standard sector, could exist at fairly low energy scales. In this article we study a selection of such models, where the secluded group either contains a softly broken U(1) or an unbroken SU(N). In the Abelian case new gamma(v) gauge bosons can be radiated off and decay back into visible particles. In the non-Abelian case there will not only be a cascade in the hidden sector, but also hadronization into new pi(v) and rho(v) mesons that can decay back. This framework is developed to be applicable both for e(+) e(-) and pp collisions, but for these first studies we concentrate on the former process type. For each Abelian and non-Abelian group we study... (More)

For each Abelian and non-Abelian group we study three different scenarios for the communication between the standard sector and the secluded one. We illustrate how to distinguish the various characteristics of the models and especially study to what extent the underlying gauge structure can be determined experimentally. (Less)
