Off-forward gluonic structure of vector mesons

The spin-independent and transversity generalized form factors (GFFs) of the ϕ meson are studied using lattice QCD calculations with light quark masses corresponding to a pion mass mπ∼450(5)  MeV. One transversity and three spin-independent GFFs related to the lowest moments of leading-twist spin-in...
