Polarized EMC effect in the Thermodynamical Bag Model

Abstract

We determine the polarized quark distributions and structure functions for nuclear media such as Li 7 and Al 27 by using a phenomenological model known as Thermodynamical Bag Model. The evaluation of nuclear medium modifications to single nucleon structure function discusses the predictions of the polarized EMC effect. The deviation of polarized EMC from unpolarized case shows quenching of polarized quark distributions and proves the significance of this study as adding the spin observables will explore more about medium modification of nuclear structure and the nature of the strong interaction.
