Light D-wave axial-tensor K2(1820) meson at finite temperature
(IOP Publishing, 2019-06)
In this work the properties of the axial-tensor K-2(1820) meson in a hot medium are investigated. The mass and the decay constant of this state are calculated via thermal QCD sum rules considering QCD condensates up to ...
Hot medium effects on pseudotensor K2(1820) meson
(EDP Sciences, 2019)
The investigation of mesons in hot medium can give valuable information about the nature of QCD vacuum and deconfinement phase transitions. In this study, thermal properties of pseudotensor K-2(1820) meson is examined via ...
B → T transition form factors in light-cone sum rules
(American Physical Society, 2019-11-11)
We present a new calculation of the semileptonic tree-level and flavor-changing neutral current form
factors describing B-meson transitions to tensor mesons T ¼ D2, K2, a2, f2 (JP ¼ 2þ). We employ the QCD light-cone sum ...
Hidden-beauty broad resonance Yb(10890) in thermal QCD
(Hindawi Limited, 2019)
In this work, the mass and pole residue of resonance Yb is studied by using QCD sum rules approach at finite temperature. Resonance Yb is described by a diquark-antidiquark tetraquark current, and contributions to operator ...
Analysis of X(4140) like states and their radial excitations in QCD
(Sissa Medialab Srl, 2017)
In this work, we investigated the X(4140) and like states and their radial excitations by using molecular and diquark-antidiquark currents which couple to scalar, axial vector and tensor states via QCD sum rules. In operator ...
