Looking for Lights from the Darkness: Signals from MeV-scale Solar Axion-like Particles
Yu-Cheng Qiu, Yongchao Zhang
The axion-like particles can be produced in the Sun via the process of , with mass up to 5.5 MeV. The photons in the subsequent decay can…
The Lifespan of our Universe
Hoang Nhan Luu, Yu-Cheng Qiu, S. -H. Henry Tye
The Dark Energy Survey (DES) and the Dark Energy Spectroscopic Instrument (DESI) measurements claim that the dark energy equation of state . This observation can be expla…
Dynamical dark energy from an ultralight axion
Hoang Nhan Luu, Yu-Cheng Qiu, S. -H. Henry Tye
Recently the Dark Energy Survey (DES) Collaboration presented evidence that the equation of state of the dark energy is varying, or if it is constant. In eith…
Baryon Number Violating Rate as A Function of the Proton-Proton Collision Energy
Yu-Cheng Qiu, S. -H. Henry Tye
The baryon-number violation (BV) happens in the standard electroweak model. According to the Bloch-wave picture, the BV event rate shall be significantly enhanced when the proton-p…
