Prospects of Particle Physics in China
Hesheng Chen (Institute of High Energy Physics, Beijing)
Seminar Room 3, 15:00
The Beijing Electron Positron Collider (BEPC) finished its running July 2005,
with great success in both the Tau-Charm physics experiment and the
synchrotron radiation light source. The latest Charm physics results from BEPC
are reviewed, including the observation of the new resonance of X1835 with a
possible explanation of the PPbar bound state. The major upgrade of BEPC into
a double ring collider, so called BEPCII, will increase its luminosity by two
orders of magnitude. The physics window of BEPCII is mainly the precision
measurements in the Charm physics and the search for new phenomena. The
construction of BEPCII is finished. The tuning of the storage ring goes
smoothly. The synchrotron radiation facility of BEPCII opened to users with
high performance since the end of 2006. The construction and assembling of the
new detector BESIII are nearly finished, and will be moved into the
interaction region next April. The non-accelerator experiments are promoted
with great efforts, including the neutrino physics experiments, the cosmic ray
measurements, and the particle astrophysics experiments in Space. The reactor
neutrino experiment at Daya Bay could reach the sensitivity of 0.01 on the
measurement of the neutrino mixing parameter sin² θ13. The medium
and long term plan of the Chinese particle physics experiments is also discussed.
