Magnetic moments of heavy barions in the bag model reexamined

“…Important modification included in Table 5 is the effect of mixing which was first addressed in [15] and studied in detail in Refs. [28,74]. The mixing appears between the states Ξ + c and Ξ + c , and between the states Ξ 0 c and Ξ 0 c .…”

“…The mixing appears between the states Ξ + c and Ξ + c , and between the states Ξ 0 c and Ξ 0 c . According to [28], the mixing is of little importance for the neutral baryons Ξ 0 c and Ξ 0 c , while it is essential for the charged ones Ξ + c and Ξ + c . This is related to different magnitude of the transition operators in Table 5,…”

“…The lack of contributions from the light degrees of freedom seems to be generic and theoretical predictions using different models show that the MDM of Λ c is close to the one predicted by the constituent quark model. MDM predictions using various theoretical models can be summarized as [15][16][17][18][19][20][21][22][23][24][25][26][27][28]:…”

In this paper, we discuss the theoretical framework and the experimental measurements of the magnetic moment of the charmed baryons. We first review the theoretical predictions of the Λ + c magnetic moment and show that the measurements of the magnetic moments of other charmed baryons, such as Ξ c , allow to perform detailed spectroscopy studies. The magnetic moment of the charm quark can be determined using radiative charmonium decay, which can be compared to the Λ + c magnetic moment within theoretical models. The present results show a tension with majority of theoretical predictions. The magnetic moment of the charmed baryons could potentially be measured directly, using bentcrystal experiments at LHC. The possibility to measure precisely the magnetic moments of charmed baryons needs precise measurement of their polarisation and weak decay parameters. In this paper, we revisit the formalism of the angular analysis needed for these measurements and make a detailed evaluation of initial polarisation of deflected Λ c baryons as a function of crystal orientation. We found a special orientation of the crystal that gives the opportunity to measure the Λ c dimensionless electric dipole moment almost with the same precision as its g-factor, which is more than an order of magnitude more efficient than suggested before.

“…There are different approaches in investigation of the structure of hadrons, especially, the most promising one in this direction is the study of the electromagnetic properties of the hadrons and their excitations. The electromagnetic transitions of doubly heavy baryons have been evaluated in the heavy baryon chiral perturbation theory [45,46], light-cone sum rules [47], the relativistic quark model [48], a nonrelativistic approach [49][50][51][52][53][54], bag Model [55], and many more.…”

We revisited the mass spectra of the Ξcc++ baryon with positive and negative parity states using Hypercentral Constituent Quark Model Scheme with Coloumb plus screened potential. The ground state of the baryon has been determined by the LHCb experiment, and the anticipated excited state masses of the baryon have been compared with several theoretical methodologies. The transition magnetic moments of all heavy baryons Ξcc++, Ξcc+, Ωcc+, Ξbb0, Ξbb−, Ωbb−, Ξbc+, Ξbc0, Ωbc0 are also calculated and their values are −1.013 μN, 1.048 μN, 0.961 μN, −1.69 μN, 0.73 μN, 0.48 μN, −1.39 μN, 0.94 μN and 0.710 μN, respectively.
