Gluon gravitational form factors at large momentum transfer

We perform a perturbative QCD analysis of the gluonic gravitational form factors (GFFs) proton and pion at large momentum transfer. derive explicit factorization formula GFFs in terms distribution amplitudes hadrons. At leading power, we find that gluon Ag Cg scale as Ag?(t)=Cg?(t)?1/(?t) for pion, Agp(t)?1/(?t)2 Cgp(t)?ln2?(?t/?2)/(?t)3 proton, respectively, where t is transfer ? non-perturbative to regulate endpoint singularity Cgp calculation. Our results provide unique perspective dependence will help improve our understanding internal pressure distributions
