On the Tensor Glueball Content of Soft Pomeron

  • We study the gluonic content of the pomeron through relating the pomeron trajectory to the observed IGJPC=0+2++ isoscalar tensor mesons. Four of these mesons satisfy the spin-mass relation of the pomeron. These pomeronian candidates may be hybrid states. One of them, the f2(2220) meson, can have a predominant glueball component. We address the unsettled experimental situation about the width of this meson and give a theoretical lower bound for it. We also show why this meson may not be seen in pp experiments.

Abstract: We study the gluonic content of the pomeron through relating the pomeron trajectory to the observed IGJPC=0+2++ isoscalar tensor mesons. Four of these mesons satisfy the spin-mass relation of the pomeron. These pomeronian candidates may be hybrid states. One of them, the f2(2220) meson, can have a predominant glueball component. We address the unsettled experimental situation about the width of this meson and give a theoretical lower bound for it. We also show why this meson may not be seen in pp experiments.
