Description

Baryon-to-meson Transition Distribution Amplitudes (TDAs) appear
as building blocks within the collinear factorized description of amplitudes
for a class of hard exclusive reactions such as hard exclusive meson
electroproduction off a baryon in the near-backward region and
baryon-antibaryon annihilation into a meson and a lepton pair.

In this talk we present a general overview of the fundamental properties
of baryon-to-meson TDAs and address their physical contents with the special
emphasize on the interpretation in the impact parameter space.
We also discuss the observable quantities
sensitive to the onset of the collinear factorization regime for the corresponding
hard exclusive reactions and consider experimental perspectives for accessing
baryon-to-meson TDAs at JLab and at future facilities such as PANDA@GSI and EIC.
