Transverse momentum dependent parton distributions in a light-cone quark model

, 2008
The leading twist transverse momentum dependent parton distributions (TMDs) are studied in a light-cone description of the nucleon where the Fock expansion is truncated to consider only valence quarks. General analytic expressions are derived in terms of

Probing light quark Yukawa couplings through angularity distributions in Higgs boson decay

Journal of High Energy Physics
We propose to utilize angularity distributions in Higgs boson decay to probe light quark Yukawa couplings at e + e − colliders. Angularities τ a are a class of 2-jet event shapes with variable and tunable sensitivity to the distribution of radiation in ...

Skewed generalized parton distributions of proton from basis light-front quantization

Physics Letters B
We obtain all the leading-twist quark generalized parton distributions (GPDs) inside the proton at nonzero skewness within the basis light-front quantization framework.

Generalized Parton Distributions in the Light-Front Constituent Quark Model

, 2004
The Generalized Parton Distributions (GPDs) of the nucleon are analyzed within the relativistic constituent quark model formulated on the light-front. It is shown that the matrix elements of the plus component of the one-body vector current are plagued ...

Generalized Transverse-Momentum Dependent Parton Distributions in Light-Cone Quark Models

, 2010
We discuss the general formalism for the calculation in light-cone quark models of the fully unintegrated, off-diagonal quark-quark correlator of the nucleon.

Generalized parton distributions for weakly bound systems from light-front quantum mechanics

, 2002
We present generalized parton distributions for weakly bound systems on the light cone in order to build intuition about the light-front formalism. Physics at the crossover is reviewed in terms of the light-cone Fock space representation. Furthermore, we

Gluon GTMDs at nonzero skewness and impact parameter dependent parton distributions

European Physical Journal C: Particles and Fields
We investigate the leading twist generalized transverse momentum dependent parton distributions (GTMDs) of the unpolarized and longitudinally polarized gluons in the nucleon.

Precise Optical Modeling of Phosphor-Converted LEDs With Arbitrary Concentration and Thickness Using Bidirectional Scattering Distribution Function

IEEE Photonics Journal, 2018
Phosphor-converted light-emitting diode (pcLED) is one of the most promising methods to generate white light. The interaction of the excitation light with the phosphor in pcLED is a complicated phenomenon, combining light absorption, light conversion ...

Short-range correlations and their implications for isospin-dependent modification of nuclear quark distributions

EPJ Web of Conferences, 2016
The past decade has provided a much clearer picture of the structure of high-momentum components in nucleons, associated with hard, short-distance interactions between pairs of nucleons.

The Statistical Study of the Daily Fermi Light Curves of 130 Sources

Galaxies, 2017
Blazars show rapid and high amplitude variability. It is interesting to question what kind of process the variability corresponds to. Maybe it is a result of the instability of the accretion flows.
