Corrected Version Transverse Angular Momentum Relations
As discussed in my Pedagogical lecture: We need expression for the non-forward matrix elements of the energy momentum tensor t . Although t transforms as a tensor under Lorentz transformations, its non-forward matrix elements do not. Erroneously assuming that they do led to the incorrect expression for the angular momentum expectation value for a transversely polarized nucleon: ⟨Ji⟩incorrect = ...
متن کاملThe Origin and Distribution of Angular Momentum in Galaxies
Cold Dark Matter with a large cosmological constant (ΛCDM) appears to fit large scale structure observations well. Of the possible small scale problems, the Central Cusps and Too Many Satellites problems now appear to be at least partly solved, so Angular Momentum has become the most serious remaining CDM problem. There are actually at least two different angular momentum problems: A. Too much ...
متن کاملBounds on Transverse Momentum Dependent Distribution Functions
Here, P and S denote the parent hadron momentum and spin, and the relevant component of the quark momentum is x = p/P, the light-cone momentum fraction. The components a = a · n∓ stem from vectors n+ and n−, satisfying n2+ = n 2 − = 0 and n+ ·n− = 1, which are fixed by the momentum that introduces the large scaleQ, together with a (soft) hadron momentum. When only the leading part in orders of ...
متن کاملThe Evolution of the Angular Momentum Distribution during Star Formation.
If the angular momentum of the molecular cloud core were conserved during the star formation process, a newborn star would rotate much faster than its fission speed. This constitutes the angular momentum problem of newborn stars. In this Letter, the angular momentum transfer in the contraction of a rotating magnetized cloud is studied with axisymmetric MHD simulations. Because of the large dyna...
متن کاملOn the Distribution of Partons in the Transverse Plane
Parton densities are among the most important sources of information on hadron structure at the level of quarks and gluons. The conventional densities describe the distribution of longitudinal momentum and helicity carried by partons in a fast-moving hadron. Generalized parton distributions (GPDs) complement this essentially one-dimensional picture with information on the directions transverse ...
