Key Details

Studies P-wave fully heavy tetraquarks with QCD sum rules

Excitation structures show some channels have pure lambda-mode

Supports X(6900) and X(7200) as P-wave cc-bar-c-bar-c states

Predicts additional bb-bar-b-bar-b states below thresholds

AI generated summary

P-wave heavy quark tetraquarks

This paper studies fully heavy P-wave tetraquarks using QCD sum rules. The excitation structures indicate some channels have pure lambda-mode excitation. Results support interpreting recent X(6900) and X(7200) as P-wave cc-bar-c-bar-c states, and predict additional bb-bar-b-bar-b states below thresholds.
