On the pion electroproduction amplitude [PDF]

Physical Review C, 2001
We analyze amplitudes for the pion electroproduction on proton derived from Lagrangians based on the local chiral SU(2) x SU(2) symmetries. We show that such amplitudes do contain information on the nucleon axial form factor F_A in both soft and hard ...

Exclusive electro-weak production of a charmed meson at high energy

SciPost Physics Proceedings, 2022
Exclusive electro-weak processes have peculiar features which make them complementary to usually discussed deeply virtual electroproduction processes such as deep virtual Compton scattering or meson production (and the corresponding crossed reactions).

Exclusive heavy vector meson electroproduction to NLO in collinear factorisation

Journal of High Energy Physics, 2021
We compute the exclusive electroproduction, γ * p → Vp, of heavy quarkonia V to NLO in the collinear factorisation scheme, which has been formally proven for this process.
