Search for low-mass resonances in four-muon final state and generic heavy Higgs bosons in same-sign two-lepton final state with the ATLAS detector
LHCb announced the discovery of new di-$J/\psi$ resonances around $6.9$ GeV in 2020, which can be seen as a $cc\bar{c}\bar{c}$ tetraquark. The final state of di-charmonium to four muons can significantly suppress backgrounds, which is also of great benefit to the search of new resonances and can al...
