Özet:

 

We review our investigations devoted to the analysis of the resonances Zc 3900 , Zc 4430 , Zc 4100 ,  X 4140 , X 4274 , a1 1420 , Y  4660 , X 2100 , X 2239 , and Y  2175  discovered in various processes by Belle,  BaBar, BESIII, D0, CDF, CMS, LHCb and COMPASS collaborations. These resonances are considered as serious  candidates to four-quark  tetraquark  exotic mesons. We treat all of them as diquark-antidiquark states with relevant  spin-parities, find their masses and couplings, as well as explore their dominant strong decay channels. Calculations  are performed in the context of the QCD sum rule method. Thus, the spectroscopic parameters of the tetraquarks  are evaluated using the two-point sum rules. For computations of the strong couplings GTM1M2  , corresponding to  the vertices TM1M2 and necessary to find the partial widths of the strong decays T → M1M2 , we employ either the  three-point or full/approximate versions of the QCD light-cone sum rules methods. Obtained results are compared with  available experimental data, and with predictions of other theoretical studies.
