Position space interpretation for generalized parton distributions
Generalized parton distributions (GPDs) [1] have attracted significant interest since it has been recognized that they can not only be probed in deeply virtual Compton scattering experiments but can also be related to the orbital angular momentum carried by quarks in the nucleon [2]. However, remarkably little is still known about the physical interpretation of GPDs, and one may ask the questio...
متن کاملGeneralized parton distributions in impact parameter space
We study generalized parton distributions in the impact parameter representation, including the case of nonzero skewness ξ. Using Lorentz invariance, and expressing parton distributions in terms of impact parameter dependent wave functions, we investigate in which way they simultaneously describe longitudinal and transverse structure of a fast moving hadron. We compare this information with the...
متن کاملCharacterizations of Certain Marshall-Olkin Generalized Distributions
Several characterizations of Marshall-Olkin generalized distributions, introduced by Gui (2013) and by Al-Saiari et al. (2014) are presented. These characterizations are based on: (i) a simple relationship between two truncated moments ; (ii) the hazard function.
متن کاملOn Bivariate Generalized Exponential-Power Series Class of Distributions
In this paper, we introduce a new class of bivariate distributions by compounding the bivariate generalized exponential and power-series distributions. This new class contains the bivariate generalized exponential-Poisson, bivariate generalized exponential-logarithmic, bivariate generalized exponential-binomial and bivariate generalized exponential-negative binomial distributions as specia...
متن کاملImpact Parameter Space Interpretation for Generalized Parton Distributions
The Fourier transform of generalized parton distribution functions at ξ = 0 describes the distribution of partons in the transverse plane. The physical significance of these impact parameter dependent parton distribution functions is discussed. In particular, it is shown that they satisfy positivity constraints which justify their physical interpretation as a probability density. The generalize...
