Description
Summary:The inclusive production of the doubly heavy baryon [I]bb is investigated with a polarized and unpolarized photon collider. The bb pair in both a color triplet and sextet has been considered to transform into [I]bb. The results indicate that the contribution from the color sextet is about 8% for [I]bb production. For the international linear collider collision energy ranging from 91 GeV to 1000 GeV, the total cross section of 3bb shows a downtrend, i.e., the production Of [I]bb has the maximal rate at x/S=91 GeV. Our results indicate that the initial beam polarization may be an important asset for the production of 3bb. At some collision point, the production rate of [I]bb can be increased by about 17% with an appropriate choice of the initial beam polarization.
