The Little Randall-Sundrum Model at the LHC

TL;DR

The paper introduces the Little Randall-Sundrum (LRS) model, a truncated warped extra-dimensional framework that improves predictions for LHC signals and suppresses unwanted precision electroweak contributions.

Contribution

It proposes a volume-truncated version of the RS model with enhanced LHC signals and reduced precision electroweak constraints, offering a more predictive and testable framework.

Findings

Enhanced di-lepton signals at the LHC by a factor of about y^3.

Suppressed contributions to electroweak and flavor observables compared to the original RS model.

A UV cutoff scale around 1000 TeV for the LRS model.

Abstract

We present a predictive warped model of flavor, cut off at an ultraviolet scale O(10^3) TeV, called the "Little Randall-Sundrum (LRS)" model. This model corresponds to a volume-truncation, by a factor y \approx 6, of the RS scenario and is holographically dual to dynamics with number of colors larger by y. With separate gauge and flavor dynamics, several unwanted contributions to precision electroweak, Z b \bar b, and flavor observables are suppressed in the LRS framework, compared with the corresponding RS case. The LRS truncation leads to a significant enhancement of the clean (golden) di-lepton LHC signals, by O(y^3).
