ΣcandΛcmagnetic moments from QCD spectral sum rules

Abstract

The QCD spectral sum rules in the presence of the external electromagnetic field F µν is used to calculate the magnetic moment of Σ c and Λ c . Our result

Magnetic moments of heavy barions in the bag model reexamined

“…Magnetic moments of quarks are proportional to the chromomagnetic moments which determine the colour-hyperfine splitting of baryon masses. Using this fact the magnetic moments of Λ c and Λ b can be obtained [31] [26], where the source of deviation is the contribution from higher-dimension condensates.…”

Feasibility of measuring the magnetic dipole moments of the charm baryons at the LHC using bent crystals

“…There has been many calculations of the MDM of the charm baryons in various models of their structure [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. As for the Λ + c baryon, majority of the calculations predict the MDM and g-factor in the ranges Thus, an experimental study of the MDM of heavy baryons can be useful to distinguish between different theoretical approaches.…”

Light cone QCD sum rules study of the semileptonic heavy ΞQ and Ξ′Q transitions to Ξ and Σ baryons

“…The mass spectrum of the heavy baryons has been studied using various methods including heavy quark effective theory [2], QCD sum rules [3][4][5][6] and some other phenomenological models [7][8][9][10][11][12]. Some electromagnetic properties of the heavy baryons and their radiative decays have been investigated in different frameworks in [6,[13][14][15][16][17][18][19][20][21][22][23][24]. The strong decays of the heavy baryons have also been in the focus of much attention, theoretically (see for instance [25][26][27] and references therein).…”
