โœฆ Synopsis

The spectral properties of hybrid meson interpolating fields are investigated.

The quantum numbers of the meson are carried by smeared-source fermion operators and highly-improved chrome-electric and -magnetic field operators composed with APEsmeared links. The effective masses of standard and hybrid operators indicate that the ground state meson is effectively isolated using both standard and hybrid interpolating fields. Focus is placed on interpolating fields in which the large spinor components of the quark and antiquark fields are merged. In particular, the effective mass of the exotic l-+ meson is reported. Further, we report some values for excited mesonic states using a variational process.

Masses of positive and negative parity excited nucleons and hyperons are calculated in quenched lattice QCD using an O(a2) improved gluon action and a fat-link clover fermion action in which only the irrelevant operators are constructed with fat links.

We study hybrid mesons from the clover and improved gauge actions at /3 = 2.6 on the anisotropic 123 x 36 lattice using our PC cluster. We estimate the mass of 1 -+ light quark hybrid as well as the mass of the charmonium hybrid. The improvement of both quark and gluonic actions, first applied to th
