Evidence for a bound H-dibaryon using lattice QCD
نویسنده
چکیده
The H-dibaryon, a J = 0 state with the valence quark content udsuds, has long been hypothesised to exist because of the attractive nature of colour magnetic gluon exchange in the flavoursinglet channel. Using lattice QCD the NPLQCD collaboration have investigated this system and evidence is presented for the existence of a stable H-dibaryon, albeit at a quark mass somewhat larger than that in nature. This calculation is reviewed and combined with subsequent calculations by the HALQCD collaboration at the SU(3) flavour symmetric point to identify bounds on the H-dibaryon mass at the physical quark masses.

Evidence for a bound H dibaryon from lattice QCD.
We present evidence for the existence of a bound H dibaryon, an I=0, J=0, s=-2 state with valence quark structure uuddss, at a pion mass of m(π)∼389 MeV. Using the results of lattice QCD calculations performed on four ensembles of anisotropic clover gauge-field configurations, with spatial extents of L∼2.0, 2.5, 3.0, and 3.9 fm at a spatial lattice spacing of b(s)∼0.123 fm, we find an H dibar...
متن کاملPresent Constraints on the H-dibaryon at the Physical Pointfrom Lattice QCD
The current constraints from lattice QCD on the existence of the H-dibaryon are discussed. With only two significant lattice QCD calculations of the H-dibaryon binding energy at approximately the same lattice spacing, the forms of the chiral and continuum extrapolations to the physical point are not determined. In this brief report, we consider the constraints on the H-dibaryon imposed by two s...
متن کاملBound H dibaryon in flavor SU(3) limit of lattice QCD.
The flavor-singlet H dibaryon, which has strangeness -2 and baryon number 2, is studied by the approach recently developed for the baryon-baryon interactions in lattice QCD. The flavor-singlet central potential is derived from the spatial and imaginary-time dependence of the Nambu-Bethe-Salpeter wave function measured in N(f)=3 full QCD simulations with the lattice size of L≃2,3,4 fm. The pote...
متن کاملExotic bound states of two baryons in light of chiral effective field theory
Baryon-baryon bound states in the strangeness S = −2, S = −3, and S = −4 sectors are considered. In particular, the dependence of the corresponding binding energies on the quark mass (or equivalently the pion mass) is explored in the framework of chiral effective field theory, in order to connect with current lattice QCD calculations. For a bound state in the ΞΞ S0 channel, predicted by our lea...
متن کاملMass of the H dibaryon.
Recent lattice QCD calculations have reported evidence for the existence of a bound state with strangeness -2 and baryon number 2 at quark masses somewhat higher than the physical values. By developing a description of the dependence of this binding energy on the up, down and strange quark masses that allows a controlled chiral extrapolation, we explore the hypothesis that this state is to be i...
