Orbital angular momentum of partially coherent beams.
The definition of the orbital angular momentum established for coherent beams is extended to partially coherent beams, expressed in terms of two elements of the beam matrix. This extension is justified by use of the Mercer expansion of partially coherent fields. General Gauss-Schell-model fields are considered, and the relation between the twist parameter and the orbital angular momentum is ana...
متن کاملThe Pion Form Factor: Sudakov Suppressions and Intrinsic Transverse Momentum
It is demonstrated that any attempt to calculate the perturbative QCD contribution to the pion form factor requires the inclusion of intrinsic transverse momentum besides Sudakov form factors. For momentum transfers of the order of a few GeV the intrinsic transverse momentum leads to a substantial suppression of the perturbative QCD contribution. Supported by the Deutsche Forschungsgemeinschaft...
متن کاملPerturbative pion-photon transition form factors with transverse momentum corrections.
We perform a perturbative QCD analysis of the quark transverse momentum effect on the pion-photon transition form factors Fπγ and Fπγ∗ in the standard light-cone formalism, with two phenomenological models of wavefunction as the input of the non-perturbative aspect of the pion. We point out that the transverse momentum dependence in both the numerator and the denominator of the hard scattering ...
متن کاملMeasurement of the orbital angular momentum spectrum of partially coherent beams.
In this work we implement a Mach-Zehnder interferometer with an image rotator in one of its arms to measure the orbital angular momentum (OAM) spectrum of a partially coherent beam. By measuring the visibility of the interference as a function of the angle of rotation, the OAM distribution can be recovered via a Fourier transform. Theoretical calculations based on the coherent mode decompositio...
متن کاملFlavor ordering of elliptic flows at high transverse momentum.
Based on the quark coalescence model for the parton-to-hadron phase transition in relativistic heavy ion collisions, we relate the elliptic flow (upsilon(2)) of high p(T) hadrons to that of high p(T) quarks. For high p(T) hadrons produced from an isospin-symmetric and quark-antiquark-symmetric partonic matter, magnitudes of their elliptic flows follow a flavor ordering as (upsilon(2,pi)=upsilon...
