Abstract

The photoproduction of doubly charmed tetraquark T_cc is predicted through the resolved channel γ+g→ → ⟨ cc ⟩[n] + c+c → T_cc+c+c at ILC and CLIC. At e⁺e^- colliders, the initial photons γ can be produced from two primary sources, well-delineated within the Weizacker Williams approximation (WWA) and the laser back-scattering (LBS). And the initial gluon can be emitted from the photon. The spin and color quantum number [n] of the intermediate diquark configuration can be ⟨ cc⟩[³S₁]_3. Then its nonperturbative hadronization to T_cc was discussed in the phenomenological potential models. Finally, the differential distributions and theoretical uncertainty of the doubly charmed tetraquark T_cc were analyzed. The conclusion is that it is promising to observe T_cc via the resolved channel of photoproduction both at the ILC and CLIC, and the results have a strong dependence on the mass of constituent charm quark m_c and the potential model.
