Colliders and Brane Vector Phenomenology

TL;DR

This paper investigates the phenomenology of brane vectors, massive gauge fields arising from brane oscillations, analyzing their interactions with the Standard Model and deriving experimental constraints from collider data.

Contribution

It introduces a method to deduce brane vector couplings using nonlinear realizations and explores their detectability at current and future colliders.

Findings

LEP and Tevatron data exclude certain brane vector parameters.

LHC and future colliders can probe additional parameter space.

Brane vectors are stable, weakly interacting, and escape detection.

Abstract

Brane world oscillations manifest themselves as massive vector gauge fields. Their coupling to the Standard Model is deduced using the method of nonlinear realizations of the spontaneously broken higher dimensional space-time symmetries. Brane vectors are stable and weakly interacting, and therefore escape particle detectors unnoticed. LEP and Tevatron data on the production of a single photon in conjunction with missing energy are used to delineate experimentally excluded regions of brane vector parameter space. The additional region of parameter space accessible to the LHC as well as a future lepton linear collider is also determined by means of this process.
