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 ...
In the pursuit of X(5568) and its charmed partner
(Jagellonian University, 2019-09)
The recent observation by the D empty set Collaboration of the first tetraquark candidate with four different quark flavors (u, d, s and b) in the B-s(0)pi(+/-) channel having a narrow structure has still not been confirmed ...
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 ...
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 ...
Mass and pole residue of Yb(10890) state with JPC = 1−− at finite temperature
(AIP Publishing, 2019)
The status of the hidden beauty state Y-b is not clear up to now. The deviations from the expected behavior can provide a clue to consider it as an exotic meson candidate. Assuming the Y-b resonance as a tetraquark, we ...
Dissociation of pseudotensor mesons π2(1670), η2(1645) and η2(1870) through critical temperature
(Springer, 2022-09-27)
We have computed the masses and decay constants of isotriplet π2(1670), the isoscalar η2(1645) and η2(1870) states as the ground-state nonet of 1 1D2 case within the Thermal QCD sum rules framework. This method is applied ...
Impact of a thermal medium on newly observed Zcs(3985) resonance and its b-partner
(Springer, 2022-05-17)
Motivated by the very recent discovery of the strange hidden-charm exotic state Zcs(3985) by the BESIII Collaboration, we study the possible interpretation of this exotic state the both at T= 0 and T≠ 0. We analytically ...
Modifications on the properties of (2317) as four-quark state in thermal medium
(Jagiellonian University, 2022)
The low mass of Ds∗0(2317) presents problems for the conventional quark model, leading to consideration of other options regarding a multi-quark system. Here, we investigate the scalar open-charm state Ds∗0(2317) and its ...
Axial-tensor meson family at T≠0
(Springer Nature, 2020-10-12)
The mass and decay constants of rho(2), omega(2) and a missing member in the 2(--) nonet along with their first excited states are analyzed by the Thermal QCD sum rules approach, including QCD condensates up to dimension ...
Melting of 𝜌2 meson at extreme temperatures
(American Institute of Physics Inc., 2019)
The thermal properties of the light tensor ρ2 meson with quantum numbers JPC = 2- are studied at finite temperature. In our calculations, two-point Thermal QCD sum rules approach is employed including contributions up to ...
