The WA102 Collaboration, D. Barberis et al
TL;DR
This paper presents a partial wave analysis of the pi0pi0 system produced in proton-proton collisions at 450 GeV/c, identifying several scalar and tensor mesons and a broad enhancement in the D-wave.
Contribution
It provides the first unambiguous physical solution for the pi0pi0 system in this energy range, revealing detailed meson resonance structures.
Findings
Evidence for f0(980), f0(1300), and f0(1500) in the S-wave
Observation of f2(1270) in the D0-wave
Detection of a broad D-wave enhancement below 1 GeV
Abstract
A partial wave analysis of the centrally produced pi0pi0 channel has been performed in pp collisions using an incident beam momentum of 450 GeV/c. An unambiguous physical solution has been found. Evidence is found for the f0(980), f0(1300) and f0(1500) in the the S-wave. and the f2(1270) is observed dominantly in the D0-wave. In addition, there is evidence for a broad enhancement in the D-wave below 1 GeV.
