Weak decays of doubly heavy baryons: the $$1/2\rightarrow 1/2$$ 1 / 2 → 1 / 2 case

− bb and focus on the decays into spin 1/2 baryons in this paper. At the quark level these decay processes are induced by the c → d/s or b → u/c transitions, and the two spectator quarks can be viewed as a scalar or axial vector diquark. We first derive the hadronic form factors for these transitions in the light-front approach and then apply them to predict the partial widths for the semileptonic and nonleptonic decays of doubly heavy baryons. We find that the number of decay channels is sizable and can be examined in future measurements at experimental facilities like LHC, Belle II and CEPC.

“…The Ξ + cc (3520) baryon was first observed by the SELEX collaboration in the Λ + c K − π + channel [3] and later corroborated in the pD + K − one [4]. However, neither BABAR [5], nor BELLE [6], nor menta. The corresponding power counting involves some difficulties when baryon loops are included in the calculation and different methods have been developed to overcome this issue such as HBChPT [37], heavy hadron (HH)ChPT, using similar techniques [38,39], and the covariant approaches: infrared [40] and EOMS [41].…”

Electromagnetic form factors of spin- 1/2 doubly charmed baryons

We study the electromagnetic form factors of the doubly charmed baryons, using covariant chiral perturbation theory within the extended on-mass-shell (EOMS) scheme. Vector-meson contributions are also taken into account. We present results for the baryon magnetic moments, charge and magnetic radii. While some of the chiral Lagrangian parameters could be set to values determined in previous works, the available lattice results for Ξ + cc and Ω + cc only allow for robust constraints on the low-energy constant (LEC) combination, c 89 (= − 1 3 c 8 + 4c 9 ). The couplings of the doubly charmed baryons to the vector mesons have been estimated assuming the Okubo-Zweig-Iizuka (OZI) rule. We also give the expressions for the form factors of the double beauty baryons considering the masses predicted in the framework of quark models. A comparison of our results with those obtained in heavy baryon chiral perturbation theory (HBChPT) at the same chiral order is made. * hillerbl@uni-mainz.de † LHCb [7] could confirm the existence of this state.On the other hand, the mass of Ξ ++ cc measured by LHCb is greater by more than 100 MeV than that of the Ξ + cc (3520) particle. This large splitting, if confirmed, would suggest that the two states are not isospin partners [8] and thus could belong to different multiplets.The scarce and conflicting experimental information has not deterred the theoretical research on the topic. Since the early works predicting the existence of doubly charmed baryons [9, 10], soon after the discovery of hidden (cc) charm states, these particles have been studied in quark models, QCD sum rules, lattice simulations, effective theories implementing heavy quark spin symmetry, etc. See, e.g., Refs. [11,12]. Most of those works address the spectroscopy of these baryons.Besides, other matters such as their decays [13-16] and electromagnetic properties have been abundantly studied. For instance, diverse quark models [17][18][19][20][21][22][23][24], the MIT bag model [25,26], the skyrmion model [27], HBChPT [28] and ChPT within the EOMS scheme [29] have been applied to study the magnetic moments of doubly charmed baryons. Both, the magnetic and the electric form factors (FF) have also been investigated in lattice QCD [30][31][32]. As expected, the lattice results show that the doubly charmed baryons have smaller radii than the singly charmed ones and than those composed of only light quarks such as the proton. However, there is some tension between the lattice results for magnetic moments and those determined in other theoretical models [31].Here, we focus on these FF, which are a quite interesting probe, as they offer an insight on the hadron structure and how its constituents are distributed.Our work is based on chiral perturbation theory (ChPT) [33][34][35][36], which provides a model independent and systematic framework to study the non-perturbative regime of the strong interaction at low energies or for soft probes. Furthermore, it is well suited to analyse the lattice data at quark(meson) masses different...

Weak decays of doubly heavy baryons: W-exchange

Since the LHCb collaboration announced the observation of the doubly charmed baryon Ξ ++ cc , a series of studies of doubly heavy baryons have been presented. In this work, I analyse the nonleptonic weak decays of doubly heavy baryons Ξ bc and Ω bc under the flavor SU (3) symmetry. I mainly focus on the W -exchange diagrams, which will contribute to the decay channels with final states are light meson and light baryon. These channels would be helpful for searching for Ξ bc and Ω bc at LHC. And these channels and relations of corresponding decay widths could be examined by the future experimental facilities such as LHC, Belle II and CEPC.
