Central production of mesons: Exotic states versus Pomeron structure
We demonstrate that the azimuthal dependence of central meson production in hadronic collisions, when suitably binned, provides unambiguous tests of whether the Pomeron couples like a conserved vector-current to protons. We discuss the possibility of discriminating between qq̄ and glueball production in such processes. Our predictions apply also to meson production in tagged two-photon events at...
متن کاملMolecular States and 1−+ Exotic Mesons
This work investigates whether the observed 1−+ exotic mesons are molecular states. We first use a potential model to calculate the spectra and lifetimes of the f0(980) and a0(980), taken to be loosely bound molecular states of KK, then apply the same scenario to the 1−+ exotic states π1(1400) and π1(1600), assuming them to be πη(1295) and πη(1440) molecules respectively. We derive the effectiv...
متن کاملEXOTIC cc̄ MESONS
A surprising number of new c¯ c mesons with masses above the D ¯ D threshold have been discovered at the B factories. Some of them are ordinary charmonium states, but others are definitely exotic mesons. The current theoretical status of the new c¯ c mesons is summarized. 1. New c¯ c mesons The discovery of charmonium in November 1974 marked the beginning of the modern era of particle physics. ...
متن کاملDiquark model of exotic mesons
This is a conference mostly devoted to diquarks. Although an exotic meson can in principle be composed of a diquark and an antidiquark, such an exotic is unlikely to be experimentally observable in the near future. The reason, according to the model, is that diquark-antidiquark exotics have masses well above the threshold for decay into two mesons, and are likely to have widths too large to mak...
متن کاملExotic Mesons, Theory and Experiment *
In this talk I summarize the status of exotic mesons, including both theoretical expectations and experimental candidates. The current experimental candidates are " spin-parity exotics " ; since these are most often considered possible hybrid mesons, the theoretical discussion will be mainly concerned with hybrids. The exotic meson candidates discussed are the surprisingly light π 1 (1400) and ...
