Ward-Takahashi identity in the light-front formalism for a bound state of fermions
Deepesh Bhamre, J. P. B. C. de Melo
We investigate the Ward-Takahashi identity at one-loop in the light-front (LF) formalism for a bound state of fermions. We consider a spinless bound state made up of two fermions i…

Pion off-shell electromagnetic form factors: data extraction and model analysis
Ho-Meoyng Choi, T. Frederico, Chueng-Ryong Ji +1
We investigate the pion electromagnetic half off-shell form factors, which parametrize the matrix element of the charged pion electromagnetic current with one leg off-mass-shell an…
