摘要：
It was pointed out earlier, that double-diffractive J/psi production may serve as an important instrument to probe the odderon. However, double-diffractive production of chi's due to pomeron-pomeron fusion, subsequently decaying into J/psi + gamma is a possibly troublesome background. Therefore, we calculate the corresponding differential cross sections for chi production and compare the obtained J/psi yield to the rate of J/psi directly produced by pomeron-odderon fusion. We show that chi production is strongly suppressed. Hence, we conclude that double-diffractive exclusive J/psi production could be the ideal process to search for the odderon.
