# Theoretical Status of Pentaquarks

## TL;DR

This paper reviews the theoretical approaches, including QCD sum rules and lattice QCD, used to search for pentaquarks, emphasizing the need to distinguish genuine exotic states from scattering states.

## Contribution

It critically examines existing theoretical methods and highlights the importance of frameworks capable of differentiating exotic pentaquarks from scattering states.

## Key findings

- Analysis of QCD sum rule results
- Evaluation of lattice QCD studies
- Emphasis on distinguishing exotic states from scattering states

## Abstract

We review the current status of the theoretical pentaquark search from the direct QCD calculation. The works from the QCD sum rule and the lattice QCD in the literature are carefully examined. The importance of the framework which can distinguish the exotic pentaquark state (if any) from the NK scattering state is emphasized.
