Offshell
Webb3 feb. 2024 · A bstract. In the context of the Standard Model effective field theory (SMEFT) we examine the constraints on the trilinear Higgs coupling that originate from off-shell Higgs production in proton-proton collisions. Our calculation of the gg → h* → ZZ → 4 ℓ process includes two-loop corrections to gluon-gluon-fusion Higgs production and ... Webb16 juni 2024 · 48. 1. If virtual particles are supposed to be some sort of Green's function excitation of a field following a particular Lagrangian or PDE (induced by the presence of another particle, free or virtual), then why are they allowed to be "off shell"? (Especially: Why are they allowed to be nonzero outside the light cone).
