A new resonant-structure and a new enhanced-structure, named Y(4660) and
Y(4008) tentatively, are observed at Belle via initial state radiation,
as announced by the Belle Collaboration (see Belle homepage:
http://belle.kek.jp/).
Two papers with these observations were submitted to Physical Review
Letters for publication recently. The nature of these newly observed
structures is still unclear.
These analysis were finished by the physicists from China in the Belle
Collaboration. The physicists from the institute of high energy physics
(IHEP), Peking University (PKU) and University of Science and Technology
of China (USTC) have cooperated as a Chinese group in the Belle
experiment at KEK since 1995, and played important role in the searches
for  mixing,
origin of the low momentum  excess
in B decays, and new resonances using the Belle data. The observations
of these two new structures, Y(4660) and Y(4008), are significant
contributions to the high energy physics society by physicists from the
IHEP-PKU-USTC group.
The studies are supported by NSFC(Natural Science Foundation of
China), KIP (Knowledge Innovation Program) of IHEP/CAS (Chinese Academy
of Sciences), and the 100 talents program of CAS. |
