| 英文摘要 | We perform a perturbative QCD analysis of the gluonic gravitational form factors (GFFs) of the proton and pion at large momentum transfer. We derive the explicit factorization formula of the GFFs in terms of the distribution amplitudes of hadrons. At the leading power, we find that the gluon GFFs A(g) and C-g scale as A(g)(pi) (t) = C-g(pi) (t) similar to 1/(-t) for pion, A(g)(p)(t) similar to 1/(-t)(2) and C-g(p)(t) similar to ln(2)(-t/Delta(2))/(-t)(3) for proton, respectively, where t is the momentum transfer and Delta a non-perturbative scale to regulate the endpoint singularity in C-g(p) calculation. Our results provide a unique perspective of the momentum dependence of the GFFs and will help to improve our understanding of the internal pressure distributions of hadrons. (C) 2021 The Author(s).
