Research output: Contribution to journalArticlepeer-review


The LHCb experiment at CERN has discovered a doubly charmed isoscalar tetraquark Tcc with the quantum numbers of ccūd¯ and mass of about 3875 MeV/c2, decaying to D0D0π+ through the intermediate channel D∗+D0. We present a study of its strange companions with the quantum numbers of ccq¯s¯, where q=u, d and isospin violation is neglected.
