Light Meson Spectroscopy
We survey the current status of light meson spectroscopy. We begin with a general introduction to meson spectroscopy and and its importance in understanding the physical states of Quantum Chromo Dynamics (QCD). Phemenological models of hadron spectroscopy are described with particular emphasis on the constituent quark model and the qualitative features it predicts for the meson spectrum. We nex...
متن کاملLight Meson Spectroscopy with the Kloe Experiment
In this paper we describe the status of the analyses in progress on light meson spectroscopy in the KLOE experiment. We present the analyses of φ decays into f 0 (980)γ and a 0 (980)γ, the Dalitz plot analysis of the η → π + π − π 0 decay, the branching ratio measurement of η → π 0 γγ, the upper limits on Br(η → 3γ) and Br(η → π + π −), the measurement of the ratio Br(φ → η ′ γ)/Br(φ → ηγ) and ...
متن کاملIssues in Light Meson Spectroscopy: the Case for Meson Spectroscopy at Cebaf
I review some outstanding issues in meson spectroscopy. The most important qualitative issue is whether hadrons with explicit gluonic degrees of freedom exist. To answer this question requires a much better understanding of conventional qq̄ mesons. I therefore begin by examining the status of conventional meson spectroscopy and how the situation can be improved. The expected properties of gluoni...
متن کاملNon Qq Light Meson Spectroscopy. Matters of Principle Exotic Mesons
In this talk I comment on some theoretical expectations for exotic light meson spectroscopy below 2 GeV and their potential interest for a future energy upgrade of DAFNE. MATTERS OF PRINCIPLE The colours we perceive around us vary almost continuously between different tones. Only careful scrutiny of the light emitted by pure substances through diffraction gratings at the end of the 19th century...
متن کاملDispersive chiral approach to Meson-meson dynamics: Spectroscopy results for light scalars and precision studies
Dispersive approaches provide model independent description of meson-meson scattering. We first review here the use of dispersion relations to obtain a model independent unitarization of Chiral Perturbation Theory amplitudes, that establish the existence of light scalar mesons and whose leading 1/Nc behavior suggest they ahve a non q̄q dominant component. We also review the forward dispersion re...
