Strange pentaquarks with a hidden heavy quark-antiquark pair

Sachiko Takeuchi, Alessandro Giachino, Makoto Takizawa +2

The strange pentaquarks with hidden heavy quark pair ( $q^{3} c c ˉ$ and $q^{3} b b ˉ$ ) are investigated by the coupled-channel quark cluster model. Two types of the $q^{3}$ color-octe…

Quark mass dependence of the $T_{cc} (3875)^{+}$ pole

F. Gil-DomÃnguez, A. Giachino, R. Molina

Recently, several LQCD simulations have proven that the interaction in the isoscalar channel in $D D^{*}$ scattering is attractive. This channel is naturally connected to the $T_{cc}(…

Fully charmed tetraquark production at the LHC experiments

Ilia Belov, Alessandro Giachino, Elena Santopinto

We develop the formalism for production of a fully heavy tetraquark and apply it to the calculation of $pp \to T_{4 c} + X$ cross-sections. We demonstrate that the production cross-sec…
