Description

Baryon-to-meson Transition Distribution Amplitudes (TDAs) appear as building blocks for amplitudes within the collinear factorized description of 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 a particular 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 experimental facilities such as PANDA@GSI-FAIR and EIC.
