abstract = {In the effective field theory (EFT), the positivity bound on dim-8 effective
operators tells us that the s2 contribution in the scattering amplitude of 2-to-2 process
geometrically corresponds to the convex cone composed of the ultraviolet (UV) states as the
extremal rays. The J-Basis method can provide a complete group theory decomposition of
the scattering amplitude on the direct product of the gauge group and the Lorentz group,
thus to search for all UV states. Compared to previous methods, which can only perform
direct product decomposition on the gauge groups, the J-Basis method greatly improves
the strictness of the restrictions and also provides a systematic scheme for calculating the
positivity bounds of the dim-8 operators.},
