Pion-pion scattering phase shifts with the stochastic LapH method
Brendan Fahy, John Bulava, Ben Hörz +3
Progress in calculating scattering phase shifts on anisotropic clover Wilson lattices is described. The stochastic LapH method facilitates computations in large volumes a…
Excited isovector mesons using the stochastic LapH method
Colin Morningstar, Brendan Fahy, You-Cyuan Jhang +3
The spectrum of excited isovector mesons is studied using a 32^3 x 256 anisotropic lattice with u,d quark masses set to give a pion mass near 240 MeV. Results in the bosonic isovec…
The lattice gradient flow at tree level
Zoltan Fodor, Kieran Holland, Julius Kuti +3
The cut-off effects of the lattice gradient flow -- often called Wilson flow -- are calculated on a periodic 4-torus at leading order in the gauge coupling. A large class of discre…
The lattice gradient flow at tree-level and its improvement
Zoltan Fodor, Kieran Holland, Julius Kuti +3
The Yang-Mills gradient flow and the observable E(t), defined by the square of the field strength tensor at t>0, are calculated at finite lattice spacing and tree-level in the gaug…
Can a light Higgs impostor hide in composite gauge models?
Zoltan Fodor, Kieran Holland, Julius Kuti +2
The frequently discussed strongly interacting gauge theory with a fermion flavor doublet in the two-index symmetric (sextet) representation of the SU(3) color gauge group is invest…
The chiral condensate from the Dirac spectrum in BSM gauge theories
Zoltan Fodor, Kieran Holland, Julius Kuti +2
The eigenvalues of the Dirac operator at finite volume encode whether or not chiral symmetry is spontaneously broken in a massless theory. We apply this framework in a particular B…
