Evidence for a Bound H-dibaryon from Lattice QCD
S. R. Beane, E. Chang, W. Detmold +8
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_pi ~ 389 MeV. Using the results of Lat…
Prediction of the Omega_bbb mass from lattice QCD
Stefan Meinel
The mass of the triply heavy baryon Omega_bbb is calculated in lattice QCD with 2+1 flavors of light sea quarks. The b quark is implemented with improved lattice NRQCD. Gauge field…
Bottomonium spectrum at order v^6 from domain-wall lattice QCD: precise results for hyperfine splittings
Stefan Meinel
The bottomonium spectrum is computed in dynamical 2+1 flavor lattice QCD, using NRQCD for the b quarks. The main calculations in this work are based on gauge field ensembles genera…
Nuclear Physics from Lattice QCD
S. R. Beane, W. Detmold, K. Orginos +1
We review recent progress toward establishing lattice Quantum Chromodynamics as a predictive calculational framework for nuclear physics. A survey of the current techniques that ar…
Heavy-Baryon Spectroscopy from Lattice QCD
Huey-Wen Lin, Saul D. Cohen, Liuming Liu +3
We use a four-dimensional lattice calculation of the full-QCD (quantum chromodynamics, the non-abliean gauge theory of the strong interactions of quarks and gluons) path integrals…
Extracting Nucleon Magnetic Moments and Electric Polarizabilities from Lattice QCD in Background Electric Fields
William Detmold, Brian C. Tiburzi, Andre Walker-Loud
Nucleon properties are investigated in background electric fields. As the magnetic moments of baryons affect their relativistic propagation in constant electric fields, electric po…
