Discovery of the X(3872)meson in 2003 ignited intense interest in exotic(neither qq nor qqq)hadrons,but a cc interpretation of this state was difficult to exclude.An unequivocal exotic was discovered in the Z_(c)(3900...

Very recently the LHCb collaboration reported their observation of the first two fully open-flavor tetraquark states,the X 0(2900)of J P=0^+and the X 1(2900)of J P=1^−.We study their possible interpretations using the...

We study the masses of Qq^- Q ^- q' states with J^PC=0^++,1++ and 2^++ in the chiral SU(3)quark model, where Q is the heavy quark (c or b) and q (q') is the light quark (u, d or s). According to our nu...

We present a way to calculate tetraquarks ratios for quark gluon plasma with diquarks, The ratios of tetraquarks over baryons produced from quark matter are high than hadronic gas model limits. It is a better way to s...
