Jikia, G Tkabladze, A Heavy quark pair production background to the Higgs signal in linearly polarized photon-photon collisions Nucl. Instrum. Methods Phys. Res., A 155-159 472 1-2 2001 2001 We review the next-to-leading-order cross-sections of the heavy quark-antiquark pair production in linearly polarized photon-photon collision. Implications for the signal of Higgs particles are discussed.
