Query: A study on central diffractive f_0(980) and f_2(1270) meson production
  at the LHC   In this contribution we report on the investigation of central diffractive
production of mesons $f_0(980)$ and $f_2(1270)$ at the energy of Large Hadron
Collider in proton-proton collisions. The cross sections and rapidity
distributions for these low-lying mesons are analyzed. The Pomeron-Pomeron
process was considered relying on a nonperturbative Pomeron model which is
justified by the low mass of considered resonances. The associated theoretical
uncertainties are discussed.
