# Production mechanism of fully heavy tetraquarks in proton-proton collisions

## Speakers

• Prof. Antoni SZCZUREK

## Abstract

We discuss the production mechanism of a fully charm tetraquark, discovered by LHCb. including SPS and DPS mechanisms. We construct a coalescence model of the tetraquark production. We calculate the distribution in $p_{t,4c}$ in the resonance mass window. The cross section for the $J/\psi J/\psi$ is also calculated. We do similar analysis for FCC. We discuss also production of $c \bar c b \bar b$ tetraquarks..
