`Some recent results on the masses of glueballs from lattice QCD'

Abstract:
I report our results (arXiv:1208.1858) for the masses of glueballs
from lattice QCD and discuss their implications for the soon to start
PANDA experiment in Germany. I review the various ways that people
have used to understand the fundamental degrees of freedom describing
the glueball spectrum. I show some preliminary results for the
glueball masses with a new form of boundary conditions.  At the end of
the talk I briefly review the recent interest in flavour singlet
mesons in strongly interacting BSM theories.
