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.
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.
