Baryonium X(1835)

TL;DR

This paper develops relativistic six-quark equations to predict the masses of baryonia, specifically nonstrange B/bar B states, by calculating their amplitudes and identifying pole positions.

Contribution

It introduces a novel relativistic six-quark framework to calculate baryonia masses without mixing quarks and antiquarks, predicting 16 new baryonia states.

Findings

Calculated 16 baryonia masses from amplitude poles

Established a relativistic six-quark equation framework

Predicted nonstrange baryonia states

Abstract

The relativistic six-quark equations including the u, d quarks and antiquarks are found. The nonstrange baryonia B/bar B are contructed without the mixing of the quarks and antiquarks. The relativistic six-quark amplitudes of the baryonia are calculed. The poles of these amplitudes determine the masses of baryonia. 16 masses of baryonia are predicted.
