Glueball Spectroscopy on S
For SU(2) gauge theory on the three-sphere we implement the influence of the boundary of the fundamental domain, and in particular the θ-dependence, on a subspace of low-energy modes of the gauge field. We construct a basis of functions that respect these boundary conditions and use these in a variational approximation of the spectrum of the lowest order effective hamiltonian.
متن کاملGlueball Spectroscopy in Regge Phenomenology *
We show that linear Regge trajectories for mesons and glueballs, and the cubic mass spectrum associated with them, determine a relation between the masses of the ρ meson and the scalar glueball, M (0 ++) = 3/ √ 2 M (ρ), which implies M (0 ++) = 1620 ± 10 MeV. We also discuss relations between the masses of the scalar and The existence of a gluon self-coupling in QCD suggests that, in addition t...
متن کاملGlueball State on Lattice
Under the quenched approximation, we perform a lattice calculation for the mass of the ground 4 glueball state in E channel on a D = 3 + 1 lattice. Our calculation shows that the mass of this state is MG(4 ) = 3.65(6)(18)GeV , which rules out the 4 or mainly 4 glueball state interpretation for ξ(2230).
متن کاملRotational spectroscopy and equilibrium structures of S3 and S4.
The sulfur molecules thiozone S3 and tetrasulfur S4 have been observed in a supersonic molecular beam in the centimeter-wave band by Fourier transform microwave spectroscopy, and in the millimeter- and submillimeter-wave bands in a low-pressure glow discharge. For S3 over 150 rotational transitions between 10 and 458 GHz were measured, and for S4 a comparable number between 6 and 271 GHz. The s...
متن کاملSlow photoelectron velocity-map imaging spectroscopy of cold thiozonide (S3(-)).
We report high-resolution anion photoelectron spectra of thiozonide (S3(-)) acquired by slow electron velocity-map imaging (SEVI). The ions were cryogenically cooled within an ion trap before photodetachment. We measure an electron affinity of 2.3630(9) eV, resolving discrepancies in previously reported photoelectron spectra that resulted from the presence of vibrational hot bands. The SEVI spe...
