Study of Rare Charged Kaon Decays and Search for Dark Sector
in Experiments at the CERN SPS

Leader:

Deputies:  

D.V. Peshekhonov
D.T. Madigozhin


Participating countries and international organizations:
Belarus, 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 the 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 to observe physics beyond the Standard Model. In addition, the characteristics of rare kaon and hyperon decays will be improved.  Straw-detectors of the NA62 high resolution magnetic spectrometer working in vacuum will be supported during experimental runs. Development of a new detector prototype based on straws with a smaller diameter will be started to use it at higher intensity of the beams. Software for simulation, data analysis and processing will be developed.

The main objective of the NA64 experiment is to search for physics beyond the SM, namely the search for the dark photon (A') and other manifestations of the dark sector in the experiments on the CERN SPS electron and muon secondary beams. Tracking detectores based on the straw tube technology will be created and supported. Software for data MC simulation and analysis will be developed.



Expected results in the current year:

In frame of NA62:

  1. NA62 and NA48/2 data analysis will be carried out.

  2. Software for the simulation of the magnetic spectrometer and full set-up will be developed; system for detector calibration and event reconstruction will be upgraded; general software of the experiment will be developed.

  3. Calibration and testing of the NA62 straw detectors will be carried out.

  4. Participation in the NA62 experimental run at the CERN SPS. 

In frame of NA64:

  1. NA64, analysis of the experimental data obtained during the 2017--2018 runs.

  2. Development and putting into operation of new track stations based on 6~mm straw tubes. Operation and support of the detectors.

  3. Equipment preparation for the 2021 run in the new experimental zone on the H4 and muon SPS channels, CERN.

  4. On-line and off-line software development, for the straw chambers analysis and for the DAQ experiment in particular.

  5. Participation in the data taking at the CERN SPS.
