  The study of the properties of pion pairs emitted in pp Central Production
Experiments (CEP) shows that a) scalar and tensor mesons production dominates
at increasing energies and that 2++ production is suppressed by selecting
events with low four momentum transfer square -t at both proton vertices and b)
pion+pion- decays of the f0(1370) meson are directly observable as an isolated
peak over a vanishing background between 1.1 and 1.6 GeV in measurements at
high energies and low -t. Together with the measurements of the decay branching
ratios of the f0(1370) into sigma sigma, rho rho, pion pion, Kaon antiKaon, eta
eta from pbar annihilation at rest, these observations point at a high glue
content of the f0(1370) and suggest that LHC and central detectors supplemented
by precision forward detectors installed in roman pots could be used as a
unique clean source of all the low energy scalars.
