Description
Investigating the internal composition of hadrons, particularly the behavior of sea quark- gluon is one of the crucial domains in particle physics. The impact of 'sea' on various electromagnetic properties has been confirmed by several theoretical and experimental observations. In the present work, we calculated the octupole moment of $J^P= \frac{3}{2}^+$ decuplet baryons using the statistical framework in conjunction with the principle of detailed balance. The statistical model assumed that hadrons can be represented as a combination of various quark-gluon Fock states $ |q\bar qg\rangle, |q\bar qgg\rangle, |q\bar qq\bar q \rangle$, $|ggg\rangle$. The relative probabilities of strange and non-strange quark-gluon Fock states are calculated by defining the relevant multiplicities in spin and color space. The detailed balance principle governs the splitting and recombination mechanisms of gluon into $q\bar q$ pairs ($\&$ vice versa) with the help of transition sub-processes like $g \rightleftharpoons q \bar q, g \rightleftharpoons gg$, and $q \rightleftharpoons qg$ in flavor space. The involvement of strange sea introduced a suppression factor $(1- C_l)^{n-1}$, depending upon the no. of $s\bar s$ pairs present in the sea and the available free energy of gluons. Due to the significantly larger mass of strange quark, this factor is applied to limit the formation of $\bar s s$ pairs. To accentuate the importance of sea, the individual contribution of sea in terms of scalar (spin-0), vector (spin-1) and tensor (spin-2) sea is also calculated. We compared our results with different theoretical predictions, as no experimental data is currently available. Our findings may contribute meaningfully to the upcoming experimental advancements.
