Magnetic moments of strange hidden-bottom pentaquarks and the role of spin flavor correlations

TL;DR

This paper studies the magnetic moments of strange hidden-bottom pentaquarks using various quark configurations, revealing that spin-flavor structure dominates over clustering details and highlighting the suppression of heavy quark contributions.

Contribution

It introduces a comprehensive analysis of magnetic moments across different configurations, emphasizing the role of spin-flavor correlations in the hidden bottom sector.

Findings

Magnetic moments are primarily governed by spin-flavor structure rather than clustering details.

Heavy quark contributions are strongly suppressed due to the large bottom quark mass.

A systematic suppression with increasing strangeness and a clear spin hierarchy are observed.

Abstract

We investigate the magnetic moments of strange hidden bottom pentaquark states within the constituent quark model considering molecular and compact configurations. The system with quark content qqqbb is analyzed in three scenarios a baryon meson molecular configuration bq1bq2q3 a diquark diquark antiquark configuration bq1q2q3b and a diquark triquark configuration bq1bq2q3. The negative parity states with are studied for strangeness. We find that for the dominant spin couplings and maximally aligned configurations the diquark diquark antiquark qqqbb and diquark triquark bqqqb descriptions yield identical or numerically very close magnetic moments indicating that in the hidden bottom sector the magnetic properties are governed primarily by the global spin flavor structure rather than clustering details. A systematic suppression with increasing strangeness and a clear spin hierarchy are observed in all configurations. Due to the large bottom quark mass, heavy quark contributions are strongly suppressed, making the magnetic moments primarily sensitive to light strange spin correlations. These results provide theoretical benchmarks for future experimental studies of exotic multiquark states.
