Possible mechanism for inclusive production of η mesons in hadron-hadron collisions
A mechanism is proposed for the inclusive production of η mesons in hadron-hadron collisions on the basis of the idea of the production of a G( 1590) meson4 in the coalescence of the gluons of colliding hadrons. This meson decays primarily by channels containing η mesons. The cross section for the inclusive production of η mesons in pp and pp collisions is estimated and found to be given approximately by the expression tfcl = 4.5[\n(s/M2G) 4.6] X10-28 cm2. At collider energies (Vi = 540 GeV) the cross section would be o^cla3.2 mb, so that the yield of η mesons in pp collisions would be close to that observed experimentally.
