Study of Rare Charged Kaon Decays and Search for Dark Sector
in Experiments at the CERN SPS
in Experiments at the CERN SPS
| Leaders: | V.D. Kekelidze Yu.K. Potrebenikov |
| Deputy: | D.V. Peshekhonov |
Participating countries and international organizations:
Belgium, Bulgaria, CERN, Canada, Chile, Czech Republic, Germany, Italy, Mexico, Romania, Russia, Slovakia, Switzerland, United Kingdom, USA.
Issues addressed and main goals of research:
Realization of the NA62 Project allows to clarify CP-violation problem, to measure precisely very rare charged kaon decay to charged pions and two neutrinos, to carry out a search for supersymmetric particles and their partners with a goal to observe a physics beyond the Standard Model. In addition, characteristics of rare kaon and hyperon decays will be improved. A high resolution straw-detectors of the NA62 magnetic spectrometer working in vacuum will be supported during experimental runs. Software for simulation, data processing and analysis will be developed.
The Na64 experiment is a fixed-target esperiment at the CERN SPS combining the active beam dump and missing energy techniques to search for rare events. The experiment will build and operate a fully germetic detector with the primary goal to search for light dark bozons (Z') from dark sector that are coupled to photons, e.g. dark photons (A'), or sub-GeV Z' coupled only to quarks. In some cases the Z' is coupled only to µ or
,
so we call the Z' the dark leptonic gauge boson. The experiment is also capable to search KL invisible decay, which is complementary
to K+ 
+ + 
, and invisible decays of 0, 
, ', KS mesons.
Expected major results in the current year:
- Data taking by the NA62 set-up and data analysis will be carried out.
- Software for the simulation of magnetic spectrometer and full set-up will
be developed; system for detector calibration and event reconstruction will be upgraded; common software of the
experiment will be developed.
- Calibration, testing a nd support of the NA62 straw detectors will be carried out.
- Tracking detectors for NA64 experiment based on the straw tube technology will be developed and manufactured.
- Data taking by the NA64 set-up and data analysis will be carried out.
