In the history of studying the spin structure of the nucleon, two important quantities playing a central role in the framework of TMD PDFs are the transversity distribution h q 1 and the Sivers function f q 1T. Their existence was conjectured by theorists more than three ...
WebHere we will briefly discuss the resulting energy/mass structure and angular momentum structure of the electron in QED, as well as different electron radii. We note that mechanical properties of the electron, which follow from the GFFs D i and C ¯ i [5], [8], were already discussed previously [24]. Webtion which defines the hadron structure: the total cross section, the slope of the diffraction peak and the param-eter ρ(s,t). Their values are connected, on the one hand, with the large-scale structure of hadrons and, on the other hand, with the first principles which lead to the theorems on the behaviorof the scattering amplitudes at ...

WebTwo knots; just two rudimentary knots, the unknot and the trefoil. That’s all we need to build a model of the elementary particles of physics, one with fermions and bosons, hadrons and leptons, interactions weak and strong and the attributes of spin, isospin, mass, charge, CPT invariance and more. There are no quarks to provide fractional charge, no gluons to …
