The QCD Spectrum
In principle lattice Monte Carlo methods are capable of precision evaluations of the QCD spectrum. Furthermore one can study the effect of varying the fundamental parameters, namely the quark masses, from their experimental values. In order to organise the discussion, I present the current state of QCD spectrum calculations by comparing them to the ideal target of perfect accuracy. The topics t...
متن کاملN ∗ Spectrum in Lattice QCD †
We investigate the mass of the parity partner N(1/2) of the nucleon N(1/2), in lattice QCD using a new lattice discretization scheme for fermions, domain wall fermions (DWF). DWF possess exact chiral symmetry and flavor symmetry, both of which are required for this problem, even at finite lattice spacing. Our calculation reproduces the large mass splitting between those two states, in good agre...
متن کاملHadron Spectrum from Lattice QCD
A brief review is given of the lattice QCD calculation of the hadron spectrum. The status of current attempts toward inclusion of dynamical up, down and strange quarks is summarized focusing on our own work. Recent work on the possible existence of pentaquark states are assessed. We touch upon the PACS-CS Project for building our next machine for lattice QCD, and conclude with a near-term physi...
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 کاملQcd-bag Mass Spectrum and Phase Transitions
We obtain the hadronic mass spectrum in the ‘bag of bags’ statistical bootstrap model (BBSBM), implementing the colorless state condition, aside of baryon and strangeness conservation, using group projection method. We study the partition function, investigate the properties of dense hadronic matter, and determine the conditions under which the system undergoes a phase transition to a deconfine...
