First concurrent extraction of the leading-order scalar and spin proton polarizabilities

TL;DR

This paper reports the first simultaneous extraction of the six leading-order proton polarizabilities using new experimental data and an innovative bootstrap-based fitting method, establishing a fundamental benchmark for future research.

Contribution

It introduces a novel bootstrap-based fitting approach and provides the first concurrent determination of all six leading-order proton polarizabilities.

Findings

Successful simultaneous extraction of all six polarizabilities

Use of high-quality experimental data

Establishment of a benchmark for future studies

Abstract

We performed the first simultaneous extraction of the six leading-order proton polarizabilities. We reached this milestone thanks to both new high-quality experimental data and an innovative bootstrap-base fitting method. These new results provide a self-consistent and fundamental benchmark for all future theoretical and experimental polarizability estimates.
