چکیده
We present the first lattice results of the spectrum of exotic vector mesons extracted from the molecular and diquark-antidiquark operators, with quark fields (cqc̄q̄), and (csc̄q̄)/(cqc̄s̄) respectively, in lattice QCD with exact chiral symmetry. Our results suggest that X(3872) and Y (4260) are in the spectrum of QCD, with JPC = 1++ and 1−− respectively. Moreover, we obtain the spectrum of heavier exotic mesons with (csc̄ū)/(cuc̄s̄), (csc̄d̄)/(cdc̄s̄), (csc̄s̄), and (ccc̄c̄), as the first theoretical predictions from lattice QCD.

Pseudovector meson with strangeness and closed-charm
We investigate the mass spectrum of 1+ exotic mesons with quark content (csc̄q̄)/(cqc̄s̄), using molecular and diquark-antidiquark operators, in quenched lattice QCD with exact chiral symmetry. For the molecular operator {(q̄γic)(c̄γ5s)− (c̄γis)(q̄γ5c)} and the diquarkantidiquark operator {[qCγic][s̄Cγ5c̄ ] − [qCγ5c][s̄Cγ i c̄ ]}, both detect a 1+ resonance with mass around 4010 ± 50 MeV in the limit mq → ...
متن کاملY ( 4260 ) on the lattice Ting
We investigate the mass spectra of closed-charm mesons with J = 1−−, for hybrid charmonium, molecules, and diquark-antidiquark operators, in quenched lattice QCD with exact chiral symmetry. For two lattice volumes 243 × 48 and 203 × 40, each of 100 gauge configurations generated with single-plaquette action at β = 6.1, we compute point-to-point quark propagators and measure the time-correlation...
متن کاملSimulation of lattice QCD with domain-wall fermions
Quantum Chromodynamics (QCD) is the fundamental theory for the interaction between quarks and gluons. It manifests as the short-range strong interaction inside the nucleus and plays an important role in the evolution of the early universe, from the quark-gluon phase to the hadron phase. To solve QCD is a grand challenge, since it requires very large-scale numerical simulations of the discretize...
متن کاملA computational system for lattice QCD with overlap Dirac quarks
We outline the essential features of a Linux PC cluster which is now being developed at National Taiwan University, and discuss how to optimize its hardware and software for lattice QCD with overlap Dirac quarks. At present, the cluster constitutes of 30 nodes, with each node consisting of one Pentium 4 processor (1.6/2.0 GHz), one Gbyte of PC800 RDRAM, one 40/80 Gbyte hard disk, and a network ...
