glueball in British English (ˈɡluːˌbɔːl) nouna hypothetical composite subatomic particle Examples of 'glueball' in a sentenceglueball New estimates on the scalar glueball mass, 'radius' and gluon condensate value have been obtained.The glueball masses obtained are consistent with previous lattice results.We show our calculations explicitly in two characteristic situations which are “scalar and tensor glueball interacting with baryons”.We investigate time-dependent deformations of those solutions in the search for gravitational duals of models of glueball inflation.Relevant examples are the ground-state energy density, the string tension, the glueball mass spectrum and the critical temperature for deconfinement.Using this method we can follow glueball correlators to temporal separations even up to 1 fermi. |
