SAGA-HE-170-01, TMU-NT-01-01 Determination of nuclear parton distributions

Parametrization of nuclear parton distributions is investigated in the leading order of αs. The parton distributions are provided at Q=1 GeV with a number of parameters, which are determined by a χ analysis of the data on nuclear structure functions. Quadratic or cubic functional form is assumed for the initial distributions. Although valence quark distributions in the medium x region are relat...

Pion structure function in nuclear medium

We study the pion structure function in nuclear medium using the Nambu and JonaLasinio model, and its implication for the nuclear pion enhancement of the sea quark distribution in nuclei. By using the operator product expansion, medium effect of the nuclear matter is incorporated in calculations of the twist-2 operators. We find density dependence of the pion structure function is rather weak a...

John Wynne Pugh: a medical saga.

John Pugh died on 21 June 1976, 40 years, all but one month, after developing Addison's disease. Save for the first three years of this period, he lived a full life both socially and professionally. He developed his illness at a time when the treatment of this disease was in the research stage, so his history is something of a medical saga which his family feel should be put on record if only, ...

N ov 1 99 6 SAGA - HE - 111 - 96 October 27 , 1996 Flavor Asymmetry ū − d̄ in the Nucleon

We give a brief summary of the Gottfried sum rule and a flavor asymmetric distribution ¯ u− ¯ d in the nucleon. First, experimental history of the sum-rule studies is discussed. Second, future prospects for studying the asymmetry at Fermilab and RHIC are discussed. We also comment on possible nuclear modification.
