“…Consequently, and in line with the above arguments and the explorations in Ref. [74], a bound state for the J = 3 2 state of 3 Λc He has been reported, with a Λ c separation energy of approximately 140 keV including Coulomb [15]. Since our interactions do not reproduce the phase shifts of the quark model perfectly over a larger energy region, we use two different realizations with cutoff 600-700 MeV.…”

“…The prospect of an ample production of baryons with charm offered by facilities such as the LHC at CERN [1][2][3], RHIC at BNL [4], J-PARC and KEK in Japan [5,6], or FAIR in Germany [7][8][9] has led to a renewed interest in the in-medium properties of such baryons [10][11][12][13] and also in the question whether they, and notably the lightest charmed baryon, the Λ c (2286), could form bound states with ordinary matter [14][15][16][17][18][19]. In fact, there is a long history of speculations about possible bound systems involving the Λ c [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] that started soon after the discovery of charmed baryons [36,37] (see also the recent reviews [38,39]).…”

“…[16] (with total angular momentum J = 1/2 and 3/2) and Ref. [15] (for J = 3/2). Note, however, that some of the Λ c N interactions employed in the former works are so strongly attractive that they even predict two-body bound states (in the 1 S 0 as well as in the 3 S 1 partial wave) with binding energies comparable to that of the deuteron.…”

Charmed nuclei are investigated utilizing ΛcN and ΣcN interactions that have been extrapolated from lattice QCD simulations at unphysical masses of mπ = 410-570 MeV to the physical point using chiral effective field theory as guideline. Calculations of the energies of Λc single-particle bound states for various charmed nuclei from 5Λc Li to 209 Λc Bi are performed using a perturbative many-body approach. This approach allows one to determine the finite nuclei Λc self-energy from which the energies of the different bound states can be obtained. Though the ΛcN interaction inferred from the lattice results is only moderately attractive, it supports the existence of charmed nuclei. Already the lightest nucleus considered is found to be bound. The spin-orbit splitting of the p-and d-wave states turns out to be small, as in the case of single Λ hypernuclei. Additional calculations based on the Faddeev-Yakubovsky equations suggest that also A = 4 systems involving a Λc baryon are likely to be bound, but exclude a bound 3 Λc He state.

We discuss the properties of the Λc baryon in nuclear matter at zero or finite temperature. Starting from the Lagrangian based on the heavy quark effective theory, we derive the effective Lagrangian for the Λc baryon existing as an impurity particle. Adopting the one-loop calculation for nucleons, we derive the effective potential as the quantity for measuring the stability of the Λc baryon in nuclear matter. The parameters in the Lagrangian are used by estimations in the lattice QCD simulations and the chiral extrapolations. We present that the Λc baryon is bound in nuclei with the binding energy of about 20 MeV at normal nuclear matter density. We discuss the case that the Λc baryon moves with constant velocity in nuclear matter. We also discuss the change of nucleon number density near the Λc baryon in nuclear matter, and show that the Λc baryon is a useful probe to research the higher density state in nuclear matter. * yasuis@keio.jp arXiv:1811.07286v1 [hep-ph]

“…Following these ideas, we will make use of a constituent quark model (CQM) tuned on the description of the N N interaction [16] as well as the meson [17] and baryon [18,19] spectra in all flavor sectors, to obtain parameter-free predictions that will hopefully be testable in future experiments. Let us note that the study of the interaction between charmed baryons has become an interesting subject in several contexts [9,[20][21][22][23] and it may shed light on the possible existence of exotic nuclei with heavy flavors [24][25][26][27][28][29].…”

We study two- and three-baryon systems with two units of charm looking for possible bound states or resonances. All two-baryon interactions are consistently derived from a constituent quark model tuned in the light-flavor hadron phenomenology: spectra and interactions. The presence of the heavy quarks makes the two-body interactions simpler than in the light-flavor sector. Our results show a narrow two-body resonance with quantum numbers $$(I,J^P)=(0,0^+)$$(I,JP)=(0,0+). It is located 6.2 MeV below the $$\Sigma _c\Sigma _c$$ΣcΣc threshold and has a width of 4.7 MeV. The foregoing two-body state contributes to generate a $$N \Sigma _c\Sigma _c$$NΣcΣc resonance with quantum numbers $$(I,J^P)=(1/2,1/2^+)$$(I,JP)=(1/2,1/2+) and a separation energy of 0.2 MeV.
