Abstract
With the discovery of a doubly charmed baryon a somewhat forgotten issue of tetraquarks containing two heavy and two light (anti) quarks, , triggered theorist's interest. We discuss quark model estimates of masses and such objects including a model where the light sector is treated as a soliton. We show that this model has different large limit than other approaches.
