We discuss deeply virtual meson production (DVMP),
focusing on the role of higher-twist contributions
in the description of deeply virtual pseudoscalar mesons
at experimentally accessible energies.
The standard collinear approach at the lowest twist does not adequately
describe deeply virtual π0 production.
By incorporating twist-2 transversity generalized parton distributions (GPDs)
and a twist-3 meson distribution amplitude,
we have determined the twist-3 contribution, which includes both
the 2-body (qˉq) ) and 3-body (qˉqg) meson Fock components.
Two methods to regularize the end-point singularities
are introduced - quark transverse momenta
and a gluon mass.
The resulting cross sections show good agreement with experimental data,
paving the way for a more comprehensive confrontation of theory
and experiment at leading order and beyond.
