Özet

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 by other collaborations. Further independent experiments are required either to confirm the X(5568) state or to set limits on its production. Though quantum numbers are not exactly clear, the results existing in the literature indicate that it is probably an axial-vector or scalar state candidate. In this study, mass and pole residue of the X (5568) resonance assumed as a tightly bound diquark, with spin-parity both J(P) = 1(+) or J(PC) = 0(++) are calculated using two-point Thermal SVZ Sum Rules technique by including condensates up to dimension six. Moreover, its partner in the charm sector is also discussed. Investigations defining the thermal properties of X(5568) and its charmed partner may provide valuable hints and information for the upcoming experiments such as CMS, LHCb and PANDA.
