Magnetic moments of decuplet baryons in an independent particle potential model

Relativistic quark model for theΩ−electromagnetic form factors

“…It is expected that inclusion of the meson cloud will increase that value [47]. Other estimates of the Ω − charge radius [11,15,21,22,37,39,41] lead to a result between 0.16 fm 2 and 0.61 fm 2 , but not all the estimates are consistent with the experimental Ω − magnetic moment. A chiral quark model with consistent exchange currents [22] that agrees with the data to a precision of better than 6% predicts < r 2 E0 >= 0.61 fm 2 .…”

“…The combination of the two results leads to µ Ω − = (−2.019 ± 0.054)µ N [1,14]. Several works followed with estimations of µ Ω − [15,16,17,18,19,20,21,22,23,24,25,26,27,28,29]. The Ω − electric quadrupole moment was also predicted [22,23,30,31,32,33,34,35,36,37,38,39,40], although there is no experimental result.…”

“…The Ω − electric quadrupole moment was also predicted [22,23,30,31,32,33,34,35,36,37,38,39,40], although there is no experimental result. Several works estimate the Ω − electromagnetic radius [11,15,21,22,37,38,39,41]. Also the Ω − magnetic octupole moment was been estimated [30,40,42].…”

Magnetic moments and charge radii of decuplet baryons in a field-theoretic quark model

“…In addition to the transition amplitudes, we also estimate here the decuplet (B) to octet (B') transition magnetic moments in the nonrelativistic and relativistic frames as and With the earlier mentioned parameters we estimate them a further understanding regarding the electromagnetic and report them in Table I11 along with an estimation in structure of baryons. an independent particle potential model [26]. At present Next with the same set of parameters as taken above there are no direct experimental data in this regard and we also estimate charge radii of all the decuplet baryons thus we believe such measurements in the future can give in the framework of the present model, using the expres- Table IV.…”
