Description
We present our recent study on baryon-baryon (BB) interactions from
lattice QCD with almost physical quark masses corresponding to
$(m_\pi,m_K)\approx(146,525)$ MeV and large volume
$(La)^4=(96a)^4\approx$ (8.2 fm)$^4$. In order to make better use of
large scale computer resources, a large number of BB interactions from
NN to $\Xi\Xi$ are calculated simultaneously. In this contribution,
we focus on the strangeness $S=-1$ channels[1] of the hyperon
interactions by means of HAL QCD method. More recent results will be
presented which include $\Lambda$N$-\Sigma$N coupled-channel potential
comprising the tensor force as well as increasing the Monte Carlo
samples than shown in the past[1].
