Saga-Yonsei Joint Workshop XVIII

20 Jan 2022, 10:00 → 28 Jan 2022, 20:40 Asia/Seoul

Saga-Yonsei Joint Workshop XVIII

We are pleased to announce the 18th 'Saga-Yonsei Partnership Program on High-Energy Physics'.  Since the 1st meeting in November 2004, the program has been held annually, alternating Saga U. and Yonsei U. as local hosts.  The program is aiming at beginning level graduate students in HEP, and consists of several regular lectures and topical seminars as well as student presentations.  

This year, once again as in the last time, we have the 18th program in online format, on Jan.20-21 and Jan.27-28.  While we miss the intimate atmosphere of face-to-face meeting and the fellowship among the HEP students of both universities, we hope the online format will be able to bring more students the opportunity of learning HEP subjects in the program.

This year, we have eight regular lectures (90-min. each) on the following subjects:
- New avenues for proton decay
- Mathematics for frontend circuit design
- Issues in cosmology: Quantum states during inflation
- Issues in cosmology: H0 tension
- Issues in collider physics and table-top particle physics 
- Homology analysis application to the QCD phase structure
- Can we prove that cosmic structures are of quantum mechanical origin?

In addition, as we usually do, we will have sessions of student presentations and short topical seminars by junior-level researchers.

We acknowledge the support by the International Partnership program of Saga University.  This program is also supported in part by NRF/BRL and BK21 programs of Yonsei University.

14:00 Welcome & opening remarks

Speaker: Prof. Takahiro Fusayasu (Saga Univ.)

14:10 Lecture 1: New Avenues for Proton Decay

Within this decade, a new generation of underground detectors—JUNO, DUNE and Hyper-Kamiokande— are projected to improve significantly on the present sensitivities to various baryon decay modes. This presents a unique opportunity to test new decay modes in supersymmetric models that have not been considered before, partially because the sensitivity to those modes was not in the reach of the past underground detectors.

Encouraged by the results in 1912.04888 and 2011.03554, where we find that in many cases, the next generation of underground detectors should be able to probe models with sparticle masses that are O(10) TeV, we would like to explore B-L and flavor violating decaying modes. Non-supersymmetric B-L violating modes were considered in 1203.5544 and flavor violating modes in the context of high-scale supersymmetry in 1312.7854. Probing supersymmetric scenarios with proton decay will give us an insight into what may lie beyond the SM, an insight that the LHC will not be able to give us, since O(10) TeV masses are beyond the reach of the LHC.
