A model for multi-quark systems
A. M. Green, P. Pennanen
As a step towards understanding multi-quark systems abundant in nature we construct a model that reproduces the binding energies of static four-quark systems. These energies have b…
Comparing improved actions for SU(2)
Petrus Pennanen, Janne Peisa
In order to help the user in choosing the right action a performance comparison is done for seven improved actions. Six of them are Symanzik improved, one at tree-level and two at…
Flux-tube Structure, Sum Rules and Beta-functions in SU(2)
A. M. Green, P. Pennanen, C. Michael
Action and energy flux-tube profiles are computed, in SU(2) with beta=2.4,2.5, for two quarks up to 1 fm apart and for which the colour fields are in their ground state (A_1g) and…
Flux-tube structure and beta-functions in SU(2)
P. Pennanen, A. M. Green, C. Michael
The spatial distribution of the action and energy in the colour fields of flux-tubes is studied in lattice SU(2) field theory for static quarks at separations up to 1 fm at beta=2.…
