Quantum statistical parton distributions

Journal of Physics A: Mathematical and General, 2002
Summary: Modified Fermi-Dirac functions for the fermionic partons and a Bose-Einstein expression for gluons allow us to successfully describe both polarized and unpolarized structure functions in terms of a small number of parameters. Definite predictions are made for \(\bar q\) distributions to be tested in forthcoming experiments.

The parton distribution in the multiperipheral parton model

Lettere al Nuovo Cimento, 1974
An attempt is made to find the parton distribution function consistent with the multiperipheral parton model using the following fundamental assumptions: each parton gives the same contribution to the distribution function, and each multiperipheral diagram satisfies the complete factorization, The one-parton distribution function is obtained and ...

Polarized parton distribution functions

Physical Review Letters, 1991
Polarized parton distribution functions for a hadron target are defined in terms of gauge-invariant correlation functions. The polarized gluon contribution to the {ital g}{sub 1} structure function of the nucleon is computed using the modified minimal-subtraction scheme as a simple example of the calculational method.
