The production mechanism of multiquark exotic hadrons in high energy multiproduction processes lies in the structure of the relevant exotic hadrons as well as in some important aspects of high energy scattering, such as multi-parton interactions, underlying events, etc. At mass pole around 2900 MeV, a family of open charm tetraquarks, T c s s and T c s ¯ s, are observed in B decay. They are also suitable for study in multiproduction processes to obtain more information on their structure. If these resonances are produced as compact four-quark states, one can predict the production properties based on the similarities in their production mechanism to those of Ξ c , Σ c , and Λ c . Physics implies that the colour and baryon number fluctuations of the preconfinement system in high energy scattering can enhance both the baryon and four-quark state production rates via 'diquark fragmentation'. We calculate the production properties of the tetraquark family T c s s and T c s ¯ s at LHC energy for the forthcoming LHC measurements. [ABSTRACT FROM AUTHOR] |
