New Dynamics (?) of $J/\psi J/\psi$ and $\Upsilon\Upsilon$ families from QCD Laplace sum rules at NLO

Motivated by the recent CMS data on a family of $2^{++}$ states from $J/\psi J/\psi$ mass spectrum, we determine the masses of the $2^{++}$ $J/\psi J/\psi$ molecule and $cc\bar c\bar c$ states, by using (for the first time) the two lowest QCD Laplace Sum Rules (LSR) moment-ratios within the standard optimization criter...
