Sea-quark dynamics in decuplet ($\frac{3}{2}^+$) $\rightarrow$ octet ($\frac{1}{2}^+$) transition quadrupole moment
We investigated the electromagnetic quadrupole transition of baryon decuplet
($J^P= \frac{3}{2}^+$) to octet ($J^P= \frac{1}{2}^+$) using the statistical
framework together with the principle of detailed balance. The statistical
approach assumed the expansion of hadrons in terms of various quark-gluon Fock
states. By specifying the appropriate multiplicity in spin, color $\&$ flavor
space, the relative probabilities of strange and non-strange quark-gluon Fock
state are calculated. These probabilities further accumulated in the form of
statistical parameters, highlighting the importance of sea quarks and gluons in
the electromagnetic transition. Our calculations includes the individual
contribution of valence and sea (scalar, vector and tensor ) to the transition
moment of baryons. The effect of flavor SU(3) symmetry and its breaking in both
valence and sea quarks is studied by incorporating the strange quark mass. The
strangeness in the sea is constrained by a suppression factor $(1-C_l)^{n-1}$,
which depends upon the free energy of gluons. The computed results get affected
upto 60 $\%$ and exhibit the dominance of octet sea. The present work has been
compared with updated experimental data and various theoretical predictions.
The results obtained may offer important insights for future experimental
studies.
