| 5. | Takashi Yamanaka, Muon g-2/EDM Experiment at J-PARC and Software Techniques, High-End Workshop (Karyashala) on "Software Tools and Techniques used in EHEP and its Applications", 2021.07, [URL], In the muon g-2, there has been a discrepancy between the measurement performed at BNL and the SM prediction. Recently, the experiment at Fermilab reported the result consistent with the BNL measurement. At J-PARC in Japan, another experiment is being prepared to measure the muon g-2 as well as the muon EDM. In this talk, overview of the muon g-2/EDM experiment at J-PARC and software techniques used in this experiment especially for tracking will be presented.. |

Yoshioka, and J-PARC E34 Collaboration, Development of Silicon Strip Detector for J-PARC Muon g-2/EDM Experiment, The 3rd International Conference on Charged Lepton Flavor Violation, 2019.06, [URL], The positron tracking detector is being developed for the J-PARC muon g−2/EDM (E34) experiment. It uses silicon strip sensors for positron detection and signals from sensors are transferred to the front-end readout system via flexible printed circuit (FPC) boards glued on the sensors. The front-end readout system consists of ASICs on FPCs and the FPGA-based readout boards. The status of these fabrications and developments are presented.. |
| 9. | Takashi Yamanaka for the J-PARC E34 Collaboration, Muon g-2/EDM Experiment at J-PARC, 2019 KPS Spring Meeting, 2019.04, A new precise muon g-2/EDM measurement is planned at J-PARC. The recent experiment at BNL measured muon g-2 at 0.54 ppm but there is a discrepancy from the Standard Model expectation by more than three standard deviations. The experiment at J-PARC aims to measure muon g-2 with a different method from BNL or another experiment ongoing at FNAL and also to improve a sensitivity to muon EDM. We use a novel technique of muon beam thermalization, accelerate muons to 300 MeV/c, inject and store them in high precision MRI-type magnet with the storage orbit diameter of 66 cm and 3 T field and focuses with weak magnetic field. Positron tracks from muon decays are reconstructed by the silicon strip detector. By using different approaches from BNL and FNAL, J-PARC experiment will provide a independent measurement. The overall design and its preparation status will be presented.. |

| 11. | Takashi Yamanaka, Muon g-2/EDM measurement at J-PARC, 10th International Workshop on Fundamental Phisics Using Atoms, 2018.01, [URL], A new precise muon g-2/EDM measurement is planned at J-PARC. The recent experiment at BNL measured muon g-2 at 0.5 ppm but there is a discrepancy from the standard model expectation by three standard deviation. The experiment at J-PARC uses a novel technique of ultra-cold muon beam, accelerates muons to 300 MeV/c, injects and stores them in ultra-high precision MRI-type magnet with 66 cm diameter and 3 T field and focuses with weak magnetic field. Positron tracks from muon decays are reconstructed by the silicon strip detector. By using different approaches from BNL and another experiment ongoing at FNL, J-PARC experiment will provide a independent measurement. The overall design and its preparation status will be reported.. |
