Kaon Isospin Fluctuations in ALICE at the LHC^{ †}

^{†}

## Abstract

**:**

## 1. Introduction

## 2. Fluctuation Observable: ${\mathbf{\nu}}_{\mathbf{dyn}}$

- the observable is robust against detection efficiency.
- it measures the relative strength of charge-charge, neutral-neutral and charge-neutral correlations
- it serves as an indicator of any anomaly in the production of kaon fluctuation which might signal the existence of kaon DCCs

## 3. Analysis Details

## 4. Results

## 5. Conclusions
