Spectroscopy with glueballs and the role of f0(1370)
Abstract
The existence of glueballs, bound states of gluons, is one of the basic predictions of QCD; the lightest state is expected to be a scalar. The experimental situation, however, is still ambiguous. The existence of f0(1370) would point to a supernumerous state within the nonet classification of scalars and would therefore provide a hint towards a glueball. In this talk we summarize some arguments in favour and against the existence of f0(1370) and discuss schemes with and without this state included.
