Proton form factor ratio measurement with BLAST
<p>The proton electric to magnetic form factor ratio ( GPE/GPM ) is related to the underlying electromagnetic structure of the proton. GPE/GPM is studied through elastic scattering using a longitudinally polarized electron beam with 0.85 GeV energy, a polarized internal hydrogen gas target and the …

Electromagnetic pion form factor at finite temperature
The electromagnetic form factor of the pion in the space-like region, and at finite temperature, Fπ(Q²,T), is obtained from a Finite Energy QCD Sum Rule. The form factor decreases with increasing T, and vanishes at some critical temperature, where the pion radius diverges, thus signalling quark …
