$\Lambda_b(6146)^0$ state newly observed by LHCb
We study the bottom Λb(6146)0 baryon, newly discovered by the LHCb Collaboration. By adopting an interpolating current of (Lρ,Lλ)=(0,2) type and D-wave nature with spin-parity quantum numbers JP=32+ for this heavy bottom baryon, we calculate its mass and residue. Using these spectroscopic parameters...
