The most recent experimental data for all measured production and decay channels of the bottomoniumlike states Z b ð10610Þ and Z b ð10650Þ are analyzed simultaneously using solutions of the Lippmann-Schwinger equations which respect constraints from unitarity and analyticity. The interaction potential in the open-bottom channels B ðÃÞBÃ þ c:c: contains short-range interactions as well as a one-pion exchange. It is found that the long-range interaction does not affect the line shapes as long as only S waves are considered. Meanwhile, the line shapes can be visibly modified once D waves, mediated by the strong tensor forces from the pion exchange potentials, are included. However, in the fit they get balanced largely by a momentum dependent contact term that appears to be needed also to render the results for the line shapes independent of the cutoff. The resulting line shapes are found to be insensitive to various higherorder interactions included to verify stability of the results. Both Z b states are found to be described by the poles located on the unphysical Riemann sheets in the vicinity of the corresponding thresholds. In particular, the Z b ð10610Þ state is associated with a virtual state residing just below the BB Ã =BB Ã threshold while the Z b ð10650Þ state most likely is a shallow state located just above the B ÃBÃ threshold.

“…Though many new exotic states named as XYZ states above DD threshold have recently been observed in different experiments, their substructures can not be explained yet clearly. There are a lot of candidates for exotic hadrons in the charmonium sector of Quantum Chromodynamics (QCD) studied at vacuum, hot medium and also in nuclear medium, such as X(3872), Z c (3900), Z c (4430), Y (4260), Z b (10610), and Z b (10650) [1][2][3][4][5][6][7][8][9][10][11][12][13] which yields a new horizon for understanding the inner structure of strongly interacting matter. Investigating for charged charmonium-like states is one of the most promising ways of searching exotic mesons, since they must contain at least four quarks and thus cannot be a conventional hadron.…”

Motivated by the very recent discovery of the strange hidden-charm exotic state Zcs(3985) by the BESIII Collaboration, we study possible interpretation of this exotic state both at T = 0 and T = 0. We analytically compute the mass and meson-current coupling constant of this resonance with spinparity J P C = 1 +− at finite temperature approximation up to sixth order of the thermal operator dimension including non-perturbative contributions. Extracting thermal mass and meson-current coupling constant sum rules, the modifications on properties of Zcs(3985) state in hot medium is determined. As a by product, the hadronic parameters of the bottom partner of Zcs( 3985) is estimated as well. Moreover the search of temperature effects on the hadronic parameters of hidden-charm meson Zcs(3985) and the bottom partner make us understand the phase transitions, chiral symmetry breaking and the properties of hot-dense matter in QCD.

“…systems employing the QCD sum rule method, where in calculations terms up to dimension eight have been used. We adopted an interpolating current including a derivative and with quantum numbers We should note that recently, in the framework of QCD sum rule method, the mass and decay constant of the h b mesons were calculated in [61] . Obtained in [61] by using the tensor-type current, the value of the decay constant for ( ) h P 1 b is 9.85% higher than, and the value of the decay constant for the ( ) h P 2 b state is 10.06% lower than the values extracted in the present work using the axialvector type current.…”

The mass and decay constant of the heavy quarkonia hQ(1P ) and hQ(2P ) (Q = b, c) with quantum numbers J P C = 1 +− are calculated in the framework of the two-point QCD sum rule method by taking into account the vacuum condensates up to eight dimensions. We compare our results for parameters of the h b (1P ) and hc(1P ) quarkonia, and their first radially excited states h b (2P ) and hc(2P ) with available experimental data as well as predictions of other theoretical studies existing in the literature. The results of present work may shed light on experimental searches for the hc(2P ) state.
