Description
In this study we have investigated the magnetic moments of octet baryons by examining
the direct impact of external magnetic fields on their constituent quarks. Strong
external magnetic fields can influence chiral symmetry breaking or its restoration, leading
to changes in effective quark masses. We have calculated the effective masses of constituent
quarks and the octet baryons in the nuclear and strange matter within the chiral
SU(3) quark mean field model and have used these as the input in SU(4) constituent
chiral quark model to compute the effective magnetic moments of octet baryons. Unlike
approaches that treat the baryons as single entity, the current approach treats quarks
as the degrees of freedom hence, we have calculated and incorporated the individual
contributions coming from valence quarks, quark sea and orbital angular momentum
of quark sea towards the total magnetic moment of baryons in the varying values of
external magnetic fields. Similar calculations have been done using other theoretical
model like method of QCD sum rules. Studying quark magnetic moments in external
fields unveils the complex interplay of baryon structure, QCD dynamics, and matter’s
response under extreme conditions.
