Hidden Bottom Pentaquark States with Spin 3/2 and 5/2

Understand

Theoretical investigations of the pentaquark states which were recently discovered provide important information on their nature and structure.

• It is necessary to study the spectroscopic parameters like masses and residues of particles belong to the class of pentaquarks and ones having similar structures.
• The mass and pole residue are quantities which emerge as the main input parameters in exploration of the electromagnetic, strong and weak interactions of the pentaquarks with other hadrons in many frameworks.
• This work deals with a QCD sum rule analysis of the spin-$3/2$ and spin-$5/2$ bottom pentaquarks with both positive and negative parities aiming to evaluate their masses and residues.
