Exotic hadron production in quark combination model
Abstract
The philosophy on production of exotic hadrons (multi-quark states) in the framework of quark combination model is investigated, taking f0(980) as an example. The production rate and pT spectra of f0(980) considered as (s s) or (s q s q) respectively, are calculated and compared in Au+Au collisions at sNN=200GeV. The unitarity of various combination models, when open for exotic hadron production, is addressed.
