- W4320853982 abstract "We employ a newly proposed Regge trajectory relation $(M-m_R)^2=alpha_x(x+c_{0x})^{gamma}$ ($gamma=4/3$, $x=l,,n_r$) to fit the heavy-heavy systems. The universality of the relation is illustrated by fitting the Regge trajectories for the fully heavy mesons, the baryons composed of a heavy quark and a heavy diquark and the tetraquarks consisting of a heavy diquark and a heavy antidiquark. As the parameters $c_{fl}=c_{fn_r}=1$, $epsilon_c$, $c_x$, $sigma$ are universal for all heavy-heavy systems, the maximum relative error of the estimated values is $4.1%$ and most of the errors are about $1%$. The estimated values obtained from the universal relation agree with the experimental and theoretical data. Moreover, we estimate crudely the masses of the orbitally and radially excited states of the $J/psi(1S)$, $Upsilon(1S)$, the $(3/2)^+$ state of $Omega_{ccb}$ and the $2^{++}$ state of tetraquark ${ccbar{c}bar{c}}$." @default.
