Core Concepts
Using QCD sum rules, the study predicts the masses and decay widths of hypothetical bbcc tetraquarks, specifically the pseudoscalar (TPS) and vector (TV) states, suggesting their unstable nature with decays into various Bc meson pairs.
Stats
The mass of the pseudoscalar tetraquark (TPS) is predicted to be (13.092 ± 0.095) GeV.
The full width of the TPS tetraquark is calculated to be (63.7 ± 13.0) MeV.
The mass of the vector tetraquark (TV) is predicted to be (13.15 ± 0.10) GeV.
The full width of the TV tetraquark is calculated to be (53.5 ± 10.3) MeV.
The mass of the B−c meson used in the calculations is (6274.47 ± 0.27) MeV.
The predicted masses for B∗−c, B−c (13P0), and B−c (11P1) mesons are 6338 MeV, 6706 MeV, and 6750 MeV, respectively.
