New constraints on the Pion EM form factor using Pi'(-Q^2)
Gauhar Abbas, B. Ananthanarayan, S. Ramanan
We study the constraints arising on the expansion parameters c and d of the Pion electromagnetic form factor from the inclusion of pure space-like data and the phase of time-like d…

Constraining the low energy Pion electromagnetic form factor with space-like and phase of time-like data
B. Ananthanarayan, S. Ramanan
The Taylor coefficients c and d of the Pion EM form factor are constrained using analyticity, knowledge of the phase of the form factor in the time-like region, 4 m_pi^2 \le t \le…
