Description
The Lambda-b baryon and B-meson candidates produced in 7-8TeV pp-colisions at ATLAS experiment and decaying into J/psi plus 2 hadrons are analysed.
The analysis is focused on studying the decays via tetraquark (X-4200) and pentaquark (Pc-4380, Pc-4450) states previously discovered by LHCb and BELLE experiments.
ATLAS Run-I data also suggest hints for the existence of some new multiquark states in B-hadron decays to be examined in Run-II data.
