摘要

In the present work, we examined the transition quadrupole moment ( \(\varDelta ^0 \rightarrow N\) ) using the statistical framework, incorporating the detailed balanced principle. The expansion of hadrons modeled in terms of various quark gluon Fock states. Each Fock state has associated probabilities in flavor, color and spin space. These probabilities are derived in terms of statistical coefficients based on appropriate multiplicities of Fock states. The individual contribution of sea components i.e. scalar, vector & tensor sea is calculated. We also addressed the SU(3) flavor symmetry breaking in sea by introducing a suppression factor \((1-C_l)^{n-1}\) due to heavy mass of strange quark. This factor limits the generation of strange \(q\bar{q}\) pairs and change the probabilities of Fock states, hence influence the value of transition quadrupole moment. Our computed results emphasize the significance of both strange and non-strange sea and provide valuable insights for future experimental studies.
