Low-lying spectrum for lattice Dirac operators with twisted mass
We analyze the low-lying spectrum and eigenmodes of lattice Dirac operators with a twisted mass term. The twist term expels the eigenvalues from a strip in the complex plane and all eigenmodes obtain a non-vanishing matrix element with γ5. For a twisted Ginsparg-Wilson operator the spectrum is located on two arcs in the complex plane. Modes due to non-trivial topological charge of the underlyin...
متن کاملFitting correlated hadron mass spectrum data.
We discuss fitting hadronic Green functions versus time t to extract mass values in quenched lattice QCD. These data are themselves strongly correlated in t. With only a limited number of data samples, the method of minimising correlated χ 2 is unreliable. We explore several methods of modelling the correlations among the data set by a few parameters which then give a stable and sensible fit ev...
متن کاملHadron mass spectrum from lattice QCD.
Finite temperature lattice simulations of quantum chromodynamics (QCD) are sensitive to the hadronic mass spectrum for temperatures below the "critical" temperature T(c) ≈ 160 MeV. We show that a recent precision determination of the QCD trace anomaly shows evidence for the existence of a large number of hadron states beyond those known from experiment. The lattice results are well represented ...
متن کاملImproving the low-lying spectrum of the overlap kernel
Unfortunately, the matrix sign function ǫ(H) is difficult to evaluate and is typically approximated by a sum over poles [1] which can be evaluated using a multi-shift conjugate gradient (CG) solver [2]. This is an iterative approximation where the number of iterations for a given accuracy depends upon the condition number of the kernel, κ(H) = |λmax/λmin|. Usually the Hermitian Wilson-Dirac ope...
متن کاملLow lying qqqqq̄ states in the baryon spectrum
The coupling to light mesons leads to large widths and shifts of the energy of the excited states in the baryon spectrum from the predictions of the constituent quark model with three valence quarks. This coupling may be modelled by admixtures of sea-quark qqq(qq̄) configurations in the resonances. Using the same schematic flavor and spin dependent interaction model, which reproduces the low lyi...
