Exclusive central diffractive production of scalar, pseudoscalar and vector mesons
Exclusive central diffractive production of scalar, pseudoscalar and vector mesons
We discuss exclusive central diffractive production of scalar (ƒ0(980), ƒ0(1370), ƒ0(1500)), pseudoscalar (η, η′(958)), and vector (ρ0) mesons in proton-proton collisions. The amplitudes are formulated in terms of effective vertices required to respect standard rules of Quantum Field Theory and propagators for the exchanged pomeron and reggeons. Different pomeron-pomeron-meson tensorial …
