Bound state structure and electromagnetic form factor beyond the ladder approximation
(2017-03-01)
We investigate the response of the bound state structure of a two-boson system, within a Yukawa model with a scalar boson exchange, to the inclusion of the cross-ladder contribution to the ladder kernel of the Bethe-Salpeter ...
Quark-antiquark correlation in the pion
(1997-09-22)
The electromagnetic tensor for inclusive electron scattering off the pion Wμν for momentum transfers such that q+ = 0, (q+ = q0 + q3) is shown to obey a sum-rule for the component W++. From this sum-rule, one can define ...

Studies on induction meter, detailing from the base part to its operation, what the behavior of the parasite currents and why they are important for this type of meter. Demonstrating the theory experienced in classrooms, ...
Light-front model of the kaon electromagnetic current
(World Scientific Publ Co Pte Ltd, 2003-01-01)
The kaon electromagnetic form factor is extracted from both components of the current: J(+) and J(-) with a pseudo-scalar coupling of the quarks to the meson. The pair production process does not contribute to J(+) in the ...
