The Production of ${\Xi }_{bb}$ at Photon Collider

Abstract

The inclusive production of the doubly heavy baryon ${\Xi }_{bb}$ is investigated at polarized and unpolar- ized photon collider. bb pair in both color triplet and sextet have been considered to transform into ${\Xi }_{bb}$. The results indicate that the contribution from color sextet is about 8% for ${\Xi }_{bb}$ production. For the ILC collision energy ranging from 91GeV to 1000GeV, the total cross section of ${\Xi }_{bb}$ shows a downtrend, i.e., the production of ${\Xi }_{bb}$ has the maximal rate at $\sqrt{S}=91GeV$. Our results indicate that the initial beam polarization may be an important asset for the production of ${\Xi }_{bb}$. At some collision point, the production rate of ${\Xi }_{bb}$ can be increased about 17% with an appropriate choice of the initial beam polarization.
