The current picture of Glueballs
نویسنده
چکیده
Some recent developments in the phenomenology of the lightest scalar glueball are summarised. Tools for determining the gluonic content of a resonance of known mass, width and J from its branching fraction in radiative quarkonium decays and production cross section in γγ collisions are presented. Two qq̄−G mixing schemes for J = 0++, inspired by the lattice, are shown to lead to similar phenomenology that may be tested at BEPC and in γγ production at LEP2. Rapporteur talk at LEAP96, Dinkelsbuhl, Germany; 27-31 Aug 1996 (based on work with C.Amsler, with G.Farrar and Z.P.Li, and with M.Teper) ∗e-mail: [email protected]

Search for Gluonic Mesons in Gluon Jets
The existence of glueballs, the bound states of two or more gluons, are an early expectation of QCD. Calculations on a space time lattice have confirmed this expectation in the quantitative analysis. Their existence though is still in doubt despite continued efforts over the years. The identification of the glueballs requires the analysis of production and decay properties of the candidate meso...
متن کاملAre Glueballs Knotted Closed Strings?
Glueballs have a natural interpretation as closed strings in Yang-Mills theory. Their stability requires that the string carries a nontrivial twist, or then it is knotted. Since a twist can be either left-handed or right-handed, this implies that the glueball spectrum must be degenerate. This degeneracy becomes consistent with experimental observations, when we identify the ηL(1410) component o...
متن کاملLattice Calculation of Glueball Matrix Elements
Matrix elements of the form < 0|Tr g2GG|G > are calculated using the lattice QCD Monte Carlo method. Here, |G > is a glueball state with quantum numbers 0++, 2++, 0−+ and G is the gluon field strength operator. The matrix elements are obtained from the hybrid correlation functions of the fuzzy and plaquette operators performed on the 124 and 144 lattices at β = 5.9 and 5.96 respectively. These ...

The current study examines the impact of different task types on learning prepositions in form and meaning- focused interaction enhancement- based classes. The participants were 57 second Year University students enrolled in three intact lab classes at Tabriz Islamic Azad University. The first group was provided with form-focused interaction enhancement, the second with the meaning-focused int...
