A di-bottomonium at the LHC?

Area of Science:

• Particle Physics
• Quantum Chromodynamics
• Hadron Spectroscopy

Background:

• The Standard Model of particle physics describes fundamental particles and forces.
• Tetraquarks, exotic hadrons composed of four quarks, present unique challenges in understanding strong interactions.
• Experimental observations of heavy quarkonium states, like X and Z bosons, require theoretical explanations.

Purpose of the Study:

• To investigate the properties of a specific di-bottomonium tetraquark state.
• To present a novel theoretical framework for diquark-antidiquark interactions within tetraquarks.
• To address open questions in the phenomenology of known tetraquark states (X, Z).

Main Methods:

• Development of a new model for diquark-antidiquark interactions.
• Calculation of the mass and decay width of the di-bottomonium tetraquark.
• Comparison of theoretical predictions with experimental data and analyses (e.g., LHCb).

Main Results:

• The study predicts the mass and decay width of the di-bottomonium tetraquark.
• The proposed model successfully resolves several outstanding issues in the phenomenology of X and Z states.
• The di-bottomonium tetraquark is predicted to exist approximately 100 MeV below the relevant threshold.

Conclusions:

• The new tetraquark model provides a consistent framework for understanding di-bottomonium states.
• The findings offer testable predictions for ongoing and future experimental searches at the LHC.
• This work contributes to a deeper comprehension of exotic hadrons and the strong nuclear force.
