Abstract

We present our recent study on baryon-baryon (BB) interactions from lattice QCD with almost physical quark masses corresponding to (mπ ,mK) ≈ (146,525) MeV and large volume (La)⁴ = (96a)⁴ ≈ (8.1 fm)⁴. In order to perform a comprehensive study of BB interactions based on lattice QCD calculation with almost physical masses and to make better use of such large scale computer resources, a large number of BB interactions from NN to ΞΞ are calculated simultaneously. In this report, we focus on the strangeness S = -1 channels of the hyperon interactions by means of HAL QCD method. The coupled-channel HAL QCD method is briefly outlined. The snapshots of central and tensor potentials in ¹S₀ and ³S₁-³D₁ channels are presented for ΛN, ∑N (both the isospin I = 1/2,3/2) and their coupled-channel systems.
