Description
We consider the probability of thermal production of uuddss states with small radii $r=01-0.4$ fm and small masses $m<2$ GeV in Pb+Pb collisions at \sqrt(s)=2.76 TeV. We use thermal model which was tuned to AGS, RHIC, LHC data and predicts $T=150-170$ MeV.
Hereby we compare the production rates for Sexaquarks with different masses and different radii.
We found that sexaquarks are produced with relatively high rates for both 0 and 0.4 fm radii and for masses of 1700 and 1960 MeV.
We estimate ratios of Sexaquarks uuddss to hadrons (protons, kaons, Lambda) and deutrons in Pb+Pb collisions at LHC.
At T=170 MeV the ratio of thermal Sexaquark with mass 1960 MeV to thermal deutron is about 0.45.
