43. Dark energy under a gauge symmetry

Hye-Sung Lee (Korea Advanced Institute of Science and Technology)

Dark energy is the least understood component of the universe despite its dominance. A proper understanding of the universe might require an investigation of the possible symmetries of the dark sector. We introduce a gauge symmetry to a quintessence dark energy field and discuss its implications.

12. P and CP tests with entangled octet baryon pairs from J/psi decay

Yong Du (TDLI-SJTU)

Symmetries are at the heart of modern particle physics, and the violation of certain discrete symmetries such as parity (P) and its combination with the charge-conjugate symmetry (CP) has been playing a significant role in our understaning of nature. In this talk, I will discuss how to test the P and the CP discrete symmetries with the angular distribution of octet baryons from J/psi decay.
