  For a long time doubts have existed on the existence of the f0(1370) meson as
an individual object distinct and separated from the sigma meson. Decays into
two charged pions of the f0(1370) are the main source of an isolated structure
localized between 1.2 and 1.5 GeV in the two charged pions mass spectrum
measured in pp Central Exclusive Production (CEP) at 200 GeV at very low four
momentum transfer squared ltl. These data confirm in the two charged pions
decay channel the existence of the f0(1370) as an isolated well identified
structure that was previously observed in K+K-, KsKs, 4 neutral pions, two
neutral pions-two charged pions and 4 charged pions decays measured in pbar
annihilations at rest. The decay branching ratios of f0(1370) into sigma-sigma,
rho-rho, pion-pion, KKbar, eta-eta relative to pion-pion decays obtained in
analysis of data of pbar annihilations at rest which treat separately f0(1370)
and sigma are respectively 5.6, 3, 1, 1, 0.02. The decay and production
properties of f0(1370) point to a large gg content. CEP interactions at very
high energies favour production of 0++ and 2++ mesons. Selection of events with
low ltl at both proton vertices suppresses 2++ structures. LHC runs dedicated
to pp CEP measurements at low ltl could then provide a unique clean source of
all the low energy scalars, cross check the pbar annihilation results and make
it clear if and where scalar gluonium is resident and the nature (composition
in terms of qqbar, qqqbarqbar, qqbar-qqbar and gg) of f0(500), f0(980),
f0(1370), f0(1500) and f0(1710).
