Glueballs on S
It is our goal to study the influence of the structure of the configuration space on the SU(2) glueball spectrum. The method we use consists of putting the theory in a finite spatial volume and reducing the full dynamics to an effective theory of a finite number of degrees of freedom [1,2]. Asymptotic freedom implies that a small volume corresponds to a small coupling constant. Hence changing t...
متن کاملGlueballs on the three-sphere
We study the non-perturbative effects of the global features of the configuration space for SU(2) gauge theory on the three-sphere. The strategy is to reduce the full problem to an effective theory for the dynamics of the low-energy modes. By explicitly integrating out the high-energy modes, the one-loop correction to the effective hamiltonian is obtained. Imposing the θ dependence through boun...
متن کاملGlueballs on a transverse lattice
Accurate non-perturbative calculations of glueballs are performed using light-front quantised SU(N) gauge theory, to leading order of the 1/N expansion. Based on early work of Bardeen and Pearson, disordered gauge-covariant link variables M on a coarse transverse lattice are used to approximate the physical gauge degrees of freedom. Simple energetics imply that, at lattice spacings of order the...
متن کاملOn S3-equivariant Homology
We prove that the group S3 (norm 1 quaternions) cannot be a geometric realization of a crossed simplicial group and construct an exact sequence connecting S3equivariant homology of an S3-space with its Pin(2)-equivariant homology. 2000 Mathematics Subject Classification. 19G38, 55T05, 22E40.
متن کاملGlueballs: A central mystery
Glueball candidates and qq̄ mesons have been found to be produced with different momentum and angular dependences in the central region of pp collisions. This talk illustrates this phenomenon and explains the φ and t dependences of mesons with JPC = 0±+, 1++, 2±+. For production of 0++ and 2++ mesons the analysis reveals a systematic behaviour in the data that appears to distinguish between qq̄ a...
