QCD Sum Rules and Soft-Hard Interplay for Hadronic Form Factors,roach, the hard contribution has strong numeric suppression by factor (α./π) ~ 0.1 for each exchange. For this reason, the soft contribution dominates at accessible momentum transfers. The “humpy” distribution amplitudes used to enhance hard terms cannot be derived from QCD sum rules in a self-consi

Light-Baryon Spectroscopy and the Electromagnetic Form Factors in the Quark Model,wo most sophisticated, available quark potential models, based respectively on the assumption of the valence + gluon dominance and on the exchange of the pseudoscalar Goldstone-bosons arising from the spontaneous breaking of chiral symmetry. It is shown that both models predict a large, similar cont

Stancuo regain his cognitive abilities after a catastrophic brain .In the early morning hours of Feb. 1, 2016, Karl Gustafson became instinctively aware that something catastrophic was happening inside him. A severe headache that had persisted for days had taken a sudden turn for the worse, and a clear in
