Geometric representation of the 2D Antiferromagnetic Ising Model with topological term at θ=π
V. Azcoiti, G. Cortese, E. Follana +1
We study the two-dimensional Antiferromagnetic Ising Model with an imaginary magnetic field iθat θ=π. We use a new geometric algorithm which does not present a sign problem. This a…
Precise Determinations of the Decay Constants of B and D mesons
Heechang Na, Chris Monahan, Christine Davies +4
Recently we studied the B, Bs, D and Ds meson decay constants using various treatments for the heavy quark. For B mesons, we determined fB, fBs, and fBs/fB with NRQCD bottom quarks…
Precision tests of the J/ψ from full lattice QCD: mass, leptonic width and radiative decay rate to η_c
G. C. Donald, C. T. H. Davies, R. J. Dowdall +5
We calculate the J/ψ mass, leptonic width and radiative decay rate to γη_c from lattice QCD including u, d and s quarks in the sea for the first time. We use the Highly Improved St…
Elucidating the Vacuum Structure of the Aoki Phase
Vicente Azcoiti, Giuseppe Di Carlo, Eduardo Follana +1
In this paper, we discuss the vacuum structure of QCD with two flavors of Wilson fermions, inside the Aoki phase. We provide numerical evidence, coming from HMC simulations in $4^4…
Heavy meson masses and decay constants from relativistic heavy quarks in full lattice QCD
C. McNeile, C. T. H. Davies, E. Follana +2
We determine masses and decay constants of heavy-heavy and heavy-charm pseudoscalar mesons as a function of heavy quark mass using a fully relativistic formalism known as Highly Im…
Critical behaviour of the O(3) nonlinear sigma model with topological term at theta=pi from numerical simulations
Vicente Azcoiti, Giuseppe Di Carlo, Eduardo Follana +1
We investigate the critical behaviour at theta=pi of the two-dimensional O(3) nonlinear sigma model with topological term on the lattice. Our method is based on numerical simulatio…
|V_cd| from D Meson Leptonic Decays
Heechang Na, Christine T. H. Davies, Eduardo Follana +2
We present an update of the D meson decay constant f_D using the Highly Improved Staggered Quark (HISQ) action for valence charm and light quarks on MILC N_f = 2+1 lattices. The ne…
