COMET [1] is an experiment that aims to search for a charged lepton flavor violation
|
||||
(CLFV) process, the muon-to-electron conversion in the presence of a nucleus,
|
||||
\muec. The process is forbidden in the Standard Model (SM), however is
|
||||
predicted to occur in various extensions of SM, such as . Current experimental
|
||||
upper limit of the branching ratio is $BR(\mu^{-} + Au \rightarrow e^{-} + Au)
|
||||
< 7 \times 10^{-13}$, set by the SINDRUM II experiment [2].
|
||||
|
||||
Using the J-PARC proton beam and the pion capture by
|
||||
a solenoidal field, COMET will have a single event sensitivity 10,000 times
|
||||
better than the current limit. The COMET collaboration has taken a phased
|
||||
approach in which the first phase, COMET Phase-I [3], starts in 2013 and
|
||||
initial data taking in around 2016. This paper provides some highlights among
|
||||
ongoing R\&D activities.
|
||||
|
||||
%Charged lepton flavor violation (CLFV) has attracted much attention from
|
||||
%experimentalists and theorists in particle physics. The CLFV rates are
|
||||
%predicted to be in the order of of $O(10^{-54})$ in the Standard Model (SM).
|
||||
%Therefore, any experimental observations of CLFV would be an unambiguous signal
|
||||
%of new physics beyond the SM. COMET [1] is an experiment
|
||||
%that aims to search for a CLFV process of muon-to-electron conversion in the
|
||||
%presence of a nucleus, \muec.
|
||||
%Using the J-PARC proton beam and the pion capture by
|
||||
%a solenoidal field, COMET expects to have a sensitivity a factor of 10,000
|
||||
%times that of the current limit. The COMET experiment has taken a phased
|
||||
%approach [2] in which the COMET Phase-I (first phase) will start its
|
||||
%construction in 2013 and initial data taking in around 2016.
|
||||
|
||||
%The COMET Phase-I will be subjected to significant backgrounds from the
|
||||
%products of the nuclear muon capture process. However, experimental data on
|
||||
%this matter is insufficient. As so, precise measurements of the products,
|
||||
%including protons, neutrons and photons, are required for the design and
|
||||
%optimization of the experiment. Detailed of these measurements will be
|
||||
%presented.
