  author={Shahin S. Agaev and Kazem Azizi and Hayriye Sundu},
  journal={The European Physical Journal C},
The spectroscopic parameters and decay channels of the doubly charged scalar, pseudoscalar and axial-vector charm–strange tetraquarks $$Z_{ \overline{c}s}=[sd][\overline{u} \overline{c}]$$Zc¯s=[sd][u¯c¯] are explored within framework of the QCD sum rule method. The masses and current couplings of these diquark–antidiquark states are calculated by means of two-point correlation functions and taking into account the vacuum condensates up to eight dimensions. To compute the strong couplings of…

Open-charm tetraquark candidate: Note on X0(2900)

Motivated by the LHCb's very recent observation of exotic ${X}_{0}(2900)$ in the ${B}^{+}\ensuremath{\rightarrow}{D}^{+}{D}^{\ensuremath{-}}{K}^{+}$ process, for which could be a good open-charm

The new $a_1(1420)$ state: structure, mass and width

The structure, spectroscopic parameters and width of the resonance with quantum numbers $J^{PC}=1^{++}$ discovered by the COMPASS Collaboration and classified as the $a_1(1420)$ meson are examined in

Spectroscopy of hidden-charm tetraquarks in diquark model

A nonrelativistic model is used to study hidden-charm tetraquarks within a diquark–antidiquark configuration. Using the perturbation theory, we estimate the masses of the heavy tetraquarks with

Spectrum and rearrangement decays of tetraquark states with four different flavors

We have systematically investigated the mass spectrum and rearrangement decay properties of the exotic tetraquark states with four different flavors using a color-magnetic interaction model. Their

Charmed-strange tetraquarks and their decays in the potential quark model

In the framework of a nonrelativistic potential quark model, we investigate the mass spectrum of the 1 S wave charmed-strange tetraquark states of cn ¯ s ¯ n and cs ¯ n ¯ n ( n = u or d ) systems.



Open charm-bottom scalar tetraquarks and their strong decays

The mass and meson-current coupling of the diquark-antidiquark states with the quantum numbers $J^{P}=0^{+}$ and quark contents $Z_{q}=[cq][\bar {b} \bar q ]$ and $Z_{s}=[cs][\bar {b} \bar s]$ are

Charmed partner of the exotic X(5568) state and its properties

The mass, decay constant and width of a hypothetical charmed partner $X_c$ of the newly observed exotic $X_b(5568)$ state are calculated using a technique of QCD sum rule method. The

Width of the exotic Xb (5568) state through its strong decay to Bs0 π

The width of the newly observed exotic state $X_b(5568)$ is calculated via its dominant strong decay to $% B_s^{0} \pi^{+}$ using the QCD sum rule method on the light-cone in conjunction with the

Doubly charmed tetraquarks in Bc and Ξbc decays

The phenomenology of the so-called $X$, $Y$ and $Z$ hadronic resonances is hard to reconcile with standard charmonium or bottomonium interpretations. It has been suggested that some of these new

Can $X(5568)$ be a tetraquark state?

Very recently, the D0 collaboration has reported the observation of a narrow structure, $X(5568)$, in the decay process $X(5568)\to B^0_s\pi^\pm$ using the 10.4${\rm fb}^{-1}$ data of $p\bar p$

Strong D s * D s η ( ′ ) and B s * B s η ( ′ ) vertices from QCD light-cone sum rules

The strong ${D}_{s}^{*}{D}_{s}{\ensuremath{\eta}}^{(\ensuremath{'})}$ and ${B}_{s}^{*}{B}_{s}{\ensuremath{\eta}}^{(\ensuremath{'})}$ vertices are studied and the relevant couplings are calculated in

P -wave coupled-channel scattering of B s π , B s * π , B K ¯ , B * K ¯ and the puzzling X ( 5568 )

The D0 collaboration has recently reported a narrow peak structure in the ${B}_{s}^{0}{\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}$ invariant-mass spectrum, which is called $X(5568)$. Its

Decoding the X(5568) as a Fully Open-Flavor sub[over ¯]d[over ¯] Tetraquark State.

The results imply that the X(5568) can be interpreted as both the scalar sub[ over ¯]d[over ¯] tetraquark state and the axial-vector one, which are in good agreement with the experimental measurement.

Treating Z(c)(3900) and Z(4430) as the ground state and first radially excited tetraquarks

Exploration of the resonances $Z_c(3900)$ and $Z(4430)$ are performed by assuming that they are ground-state and first radial excitation of the same tetraquark with $J^{P}=1^{+}$. The mass and
