Revisit the \(X\)(4274) as the Axialvector Tetraquark State

In this article, we construct the [sc] A [sc] V -[sc] V [sc] A -type tensor current to study the mass and width of the X(4274) with the QCD sum rules in detail. The predicted mass M X = (4.27 0.09) GeV for the J P C = 1 ++ tetraquark state is in excellent agreement with the experimental data 4273.3 8.3 +17.2 -3.6 MeV from the LHCb Collaboration. The central value of the width (X(4274) J/) = 47.9 MeV is in excellent agreement with the experimental data 56 11 +8 -11 MeV from the LHCb Collaboration. The present work supports assigning the X(4274) to be the
