From July 10 to 14, our young research team had the privilege of immersing ourselves in the enriching environment of the SUT-PSI School of Muon and Neutron Physics, hosted by the prestigious Suranaree University of Technology (SUT). The well-curated curriculum showcased an engaging blend of theoretical and practical elements, designed to stimulate intellectual curiosity and enhance our understanding of low-energy particle physics.

The course schedule was meticulously planned, encompassing extensive lectures on the multifaceted roles of muons and neutrons in low-energy particle physics. Additionally, hands-on tutorial sessions offered invaluable insights into cutting-edge practices in particle physics simulation and analysis. This was supplemented by an eye-opening tour to the Thai Synchrotron Light Research Institute, a beacon of scientific progress and innovation in the region.

The academic rigor was perfectly balanced with cultural immersion and networking opportunities. A memorable visit to the Phimai Historical Park allowed us to appreciate the rich heritage of Thailand, while lively discussions with fellow physicists facilitated the exchange of ideas and sparked novel perspectives. Moreover, shared experiences over delectable Thai cuisine and vibrant social activities fostered enduring connections with physicists from Thailand, Switzerland, Indonesia, and Malaysia. This incredible blend of scholarly pursuits and cultural exploration has greatly enriched our group’s collective experience and expanded our horizons.

“Under the guidance of Kim Siang, we traveled to Thailand to attend a summer school on muon and neutron physics, jointly organized by SUT and PSI. The school covered multiple aspects of muon and neutron physics, including fundamental concepts such as the muon g-2, muon EDM, neutron EDM, and others, as well as applied physics related to muon and neutron. The lecturers delivered understandable and instructive presentations, from which I learned a great deal. Meanwhile, we also toured the Thai Synchrotron National Lab, where some very interesting research is being conducted based on the light source. I was impressed by the relaxed atmosphere and approachable lecturers. We thoroughly enjoyed the physics! Another highlight was viewing the Milky Way! It was a truly enjoyable trip that I greatly appreciated.” – Yonghao Zeng

“Attending the Neutron and Muon Physics Summer School in Thailand, organized by Suranaree University of Technology and Paul Scherrer Institute, was an incredible experience. The school offered a deep dive into neutron and muon physics, fostering invaluable interactions with experts. Klaus’ insights on low-energy particle physics and muon experiments were impactful, as were presentations on ultracold neutrons and PSI beamlines. I benefited greatly from Andreas’ lecture on beam dynamics and Philip’s work on neutron and muon EDM measurements, while Yoshio’s entropy gravity theory and its neutron beam verification were fascinating. Narongrit’s session on particle physics experiments and muon X-ray fundamentals was essential for muon detection. My supervisor, Kim Siang, delivered a comprehensive review of muon g-2 and particle physics simulations, enriching my knowledge of simulation research. Aside from academics, I enjoyed engaging with international students, exploring Suranaree University’s environment, and indulging in Thai cuisine. I also appreciated the local traditions and lifestyle. My gratitude extends to everyone who made this enriching experience possible, reinforcing my determination to delve deeper into muon and particle physics research.” – Jiangtao Wang

J-PARC Muon g-2/EDM collaboration meeting and New Physics Forum

by

From June 11th to 15th, our team members Tianqi Hu, Jun Kai Ng, and Yonghao Zeng embarked on their inaugural trip to Japan. During their visit, they engaged in a variety of academic activities at the esteemed institutions of KEK, J-PARC, and Ochanomizu University, all centered around muon physics and new physics beyond the Standard Model. The trio further enriched these academic exchanges by delivering plenary talks in a dedicated session designed for visitors from Shanghai Jiao Tong University (SJTU). The narratives of their unique experiences during this trip are shared below:

“The J-PARC Muon g-2/EDM Collaboration Meeting was an unparalleled gathering. It brought together leading scientists from Canada, the UK, and Japan to delve into the nuances of muon g-2/EDM theory and experiment. The meeting served as a vital forum for pioneering research, fostering innovative ideas, and stretching the boundaries of knowledge in this captivating field. As guests, we had the opportunity to tour the J-PARC experimental facility and present the PSI Muon EDM experiment. The in-depth discussions around the experiment’s design and diverse topics, including theoretical EDM, cosmology, and dark matter, enriched our understanding. The knowledge gleaned, particularly about the detector details, will greatly benefit my Ph.D. research project.” – Tianqi Hu

“Participating in the J-PARC Muon g-2/EDM collaboration meeting presented a unique opportunity to understand the experiment from a student’s perspective, deeply involved with the Fermilab g-2 experiment. The comprehensive presentations and discussions offered insights into various aspects of designing experiments – from muon sources and linac to storage magnets, detectors, and computational physics. Having the privilege of delivering an oral presentation, I encouraged our collaborators to explore the nuances between the two experiments, concerning their physics goals, experimental designs, and potential systematics. The tour of the J-PARC experimental site was an added bonus.” – Jun Kai Ng

“The in-person collaboration meeting at J-PARC was a first-time experience for me. It offered us, who are part of the Fermilab Muon g-2 experiment, a chance to understand an under-construction experiment from multiple perspectives – data analysis, hardware, data acquisition, and more. The meeting’s presentations covered detailed aspects and latest updates of the experiment, along with two invited talks about the future of muon g-2 and lattice QCD calculations of muon g-2. Amidst the meeting, I gave my first-ever oral presentation. While it was nerve-wracking, and despite feeling somewhat underprepared, it was a significant learning experience and an enjoyable part of the trip!” – Yonghao Zeng
