The Cheshire Cat Principle from Holography

TL;DR

This paper explores how the Cheshire Cat principle, which suggests hadronic observables are independent of quark or meson distinctions, naturally arises in holographic models of chiral baryons, exemplified through baryonic form factors.

Contribution

It demonstrates the emergence of the Cheshire Cat principle within holographic descriptions of chiral baryons, linking the concept to the holographic direction.

Findings

Cheshire Cat principle appears in holographic models.

Baryonic form factors illustrate the principle.

Holographic direction encodes the 'smile' of the principle.

Abstract

The Cheshire cat principle states that hadronic observables at low energy do not distinguish between hard (quark) or soft (meson) constituents. As a result, the delineation between hard/soft (bag radius) is like the Cheshire cat smile in Alice in wonderland. This principle reemerges from current holographic descriptions of chiral baryons whereby the smile appears in the holographic direction. We illustrate this point for the baryonic form factor.
