Ξcγ→Ξc′transition in lattice QCD

Abstract

In this presentation, we summarize selectively recent results of the electromagnetic form factors of singly heavy baryons with spin 1/2 and related quantities, which were derived within a framework of the self-consistent chiral quark-soliton model. The results are compared with those from the lattice QCD and their physical implications are discussed.Keywords: the chiral quark-soliton model, pion mean fields, singly heavy baryons, electromagnetic form factors *

Decay properties of singly charmed baryons

“…The recent paper of G. J. Wang et al [18] based on heavy chiral perturbation theory and K. U. Can et al [22], H. Bahtiyar et al [23,24] based on lattice QCD, their calculated magnetic moments for J P = 1 2 + are lesser than our predictions.…”

Singly heavy baryons with chiral partner structure in a three-flavor chiral model

“…and the predicted values are shown in Table XIV and XV with the ones in Ref. [18,31]. Our results are consistent with the lattice results in Ref.…”

“…[30]), lattice simulations (e.g., Refs. [31,32]), molecule models (e.g., Refs. [33,34]) (See for a review, e.g., Ref.…”

“…[35] and references therein.). In this paper, we make comparisons of our predictions with those in chiral effective models [17,18], quark models [20,25,30], and lattice simulations [31,32]. This paper is organized as follows: We construct an effective Lagrangian in section II.…”

Radiative transitions of doubly charmed baryons in lattice QCD

“…We have been unable to reproduce the experimental Ω mass in our previous studies with κ s = 0.13640 as tuned by the PACS-CS Collaboration to physical strange quark mass with respect to the mass of Ω baryon. Our determination of the mass of Ω on the κ sea ud = 0.13781 ensemble with κ val s = 0.13640 is m Ω = 1.790 (17) GeV, which overestimates the experimental value by ∼ 6% [43]. It is, however, in agreement with the PACS-CS value reported from the same ensemble, m Ω = 1.772 (7) GeV [39].…”
