Can the nearly conformal sextet gauge model hide the Higgs impostor?

Zoltán Fodor, Kieran Holland, Julius Kuti +3

New results are reported from large scale lattice simulations of a frequently discussed strongly interacting gauge theory with a fermion flavor doublet in the two-index symmetric (…

Nucleon Structure from Lattice QCD Using a Nearly Physical Pion Mass

J. R. Green, M. Engelhardt, S. Krieg +3

We report the first Lattice QCD calculation using the almost physical pion mass mpi=149 MeV that agrees with experiment for four fundamental isovector observables characterizing th…

Meson and Baryon dispersion relations with Brillouin fermions

Stephan Durr, Giannis Koutsou, Thomas Lippert

We study the dispersion relations of mesons and baryons built from Brillouin quarks on one N_f=2 gauge ensemble provided by QCDSF. For quark masses up to the physical strange quark…

<x>_{u-d} from lattice QCD at nearly physical quark masses

Gunnar S. Bali, Sara Collins, Mridupawan Deka +7

We determine the second Mellin moment of the isovector quark parton distribution function <x>_{u-d} from lattice QCD with N_f=2 sea quark flavours, employing the non-perturbatively…

Nucleon Scalar and Tensor Charges from Lattice QCD with Light Wilson Quarks

J. R. Green, J. W. Negele, A. V. Pochinsky +3

We present 2+1 flavor Lattice QCD calculations of the nucleon scalar and tensor charges. Using the BMW clover-improved Wilson action with pion masses between 150 and 350 MeV and th…

QCD quark condensate in external magnetic fields

G. S. Bali, F. Bruckmann, G. Endrodi +3

We present a comprehensive analysis of the light condensates in QCD with 1+1+1 sea quark flavors (with mass-degenerate light quarks of different electric charges) at zero and nonze…

Isospin breaking in octet baryon mass splittings

R. Horsley, J. Najjar, Y. Nakamura +4

Using an SU(3) flavour symmetry breaking expansion in the quark mass, we determine the QCD component of the nucleon, Sigma and Xi mass splittings of the baryon octet due to up-down…

A Lattice Study of the Glue in the Nucleon

R. Horsley, R. Millo, Y. Nakamura +7

By introducing an additional operator into the action and using the Feynman-Hellmann theorem we describe a method to determine both the quark line connected and disconnected terms…

SU(2) chiral perturbation theory low-energy constants from 2+1 flavor staggered lattice simulations

Szabolcs Borsanyi, Stephan Durr, Zoltan Fodor +4

We extract the next-to-leading-order low-energy constants \bar\ell_3 and \bar\ell_4 of SU(2) chiral perturbation theory, based on precise lattice data for the pion mass and decay c…

Systematic errors in partially-quenched QCD plus QED lattice simulations

Antonin Portelli, Stephan Dürr, Zoltán Fodor +9

At the precision reached in current lattice QCD calculations, electromagnetic effects are becoming numerically relevant. Here, electromagnetic effects are included by superimposing…
