Masses of tetraquarks with open charm and bottom

Understand

The masses of the heavy tetraquarks with open charm and bottom are calculated within the diquark-antidiquark picture in the framework of the relativistic quark model.

• The dynamics of the light quarks and diquarks is treated completely relativistically.
• The diquark structure is taken into account by calculating the diquark-gluon form factor.
• New experimental data on charmed and charmed-strange mesons are discussed.
