The interactions between two octet baryons are studied at low energies using lattice QCD (LQCD) with larger-than-physical quark masses corresponding to a pion mass of $m_{\pi}\sim 450$ MeV and a kaon mass of $m_{K}\sim 596$ MeV. The two-baryon systems that are analyzed range from strangeness $S=0$ to $S=-4$ and include the spin-singlet and triplet $NN$, $\Sigma N$ ($I=3/2$), and $\Xi\Xi$ states, the spin-singlet $\Sigma\Sigma$ ($I=2$) and $\Xi\Sigma$ ($I=3/2$) states, and the spin-triplet $\Xi…

Neutrinoless Double-Beta Decay: A Roadmap for Matching Theory to Experiment
The observation of neutrino oscillations and hence non-zero neutrino masses provided a milestone in the search for physics beyond the Standard Model. But even though we now know that neutrinos are
Strangeness $S = -2$ baryon-baryon interactions and femtoscopic correlation functions in covariant chiral effective field theory
We study the baryon-baryon interactions with strangeness S = − 2 and corresponding momentum correlation functions in leading order covariant chiral effective field theory. The relevant low energy
Hyperons in Finite and Infinite Nuclear Systems
In this work, we shortly review the role and properties of hyperons in finite and infinite nuclear systems such as hypernuclei and neutron stars. Particularly, we describe different production
Two-nucleon S -wave interactions at the SU(3) flavor-symmetric point with mud≈msphys : A first lattice QCD calculation with the stochastic Laplacian Heaviside method
We report on the first application of the stochastic Laplacian Heaviside method for computing multiparticle interactions with lattice QCD to the two-nucleon system. Like the Laplacian Heaviside


Two nucleon systems at $m_\pi\sim 450~{\rm MeV}$ from lattice QCD
Nucleon-nucleon systems are studied with lattice quantum chromodynamics at a pion mass of $m_\pi\sim 450~{\rm MeV}$ in three spatial volumes using $n_f=2+1$ flavors of light quarks. At the quark
Review of lattice results concerning low-energy particle physics
The determination of the light-quark masses, the form factor, and the decay constant ratio arising in the semileptonic $$K \rightarrow \pi $$K→π transition at zero momentum transfer are reported on.
Precise determination of the I = 2 ππ scattering length from mixed-action lattice QCD
The $I=2$ $\ensuremath{\pi}\ensuremath{\pi}$ scattering length is calculated in fully dynamical lattice QCD with domain-wall valence quarks on the asqtad-improved coarse MILC configurations (with
Low-energy theorems for nucleon-nucleon scattering at M π = 450 MeV
We apply the low-energy theorems to analyze the recent lattice QCD results for the two-nucleon system at a pion mass of ${M}_{\ensuremath{\pi}}\ensuremath{\simeq}450$ MeV obtained by the NPLQCD
Strangeness S=−2 baryon-baryon interactions in relativistic chiral effective field theory
We study the strangeness $S=-2$ baryon-baryon interactions in relativistic chiral effective field theory at leading order. Among the 15 relevant low energy constants, eight of them are determined by
Are two nucleons bound in lattice QCD for heavy quark masses? Consistency check with Lüscher’s finite volume formula
On the basis of the L\"uscher's finite volume formula, a simple test (sanity check) is introduced and applied to inspect the recent claims of the existence of the nucleon-nucleon ($NN$) bound
Hyperon–nucleon interaction within chiral effective field theory revisited
The $$\varLambda N$$ Λ N and $$\varSigma N$$ Σ N interactions are considered at next-to-leading order in SU(3) chiral effective field theory. Different options for the low-energy constants that
Baryon-Baryon Interactions and Spin-Flavor Symmetry from Lattice Quantum Chromodynamics
Lattice quantum chromodynamics is used to constrain the interactions of two octet baryons at the $SU(3)$ flavor-symmetric point, with quark masses that are heavier than those in nature (equal to that

The results of the Nijmegen soft-core potential model are presented for the low-energy YN interactions and the multichannel Schrodinger equation is solved in configuration space for the (partially) nonlocal potentials.
