Revisiting the Ultraviolet Tail of the Primordial Gravitational Wave

Kavli Affiliate: Misao Sasaki | First 5 Authors: Shi Pi, Misao Sasaki, Ao Wang, Jianing Wang, | Summary: High-frequency primordial gravitational waves (PGWs) with wave numbers larger than the Hubble parameter at the end of inflation are originated from the ultraviolet (UV) modes, which are never stretched out of the horizon. Such a UV tail […]

Revisiting for maximal flavor violating $Z^{‘}_{eμ}$ and its phenomenology constraints

Kavli Affiliate: Jia Liu | First 5 Authors: Jia Liu, Muyuan Song, Haohao Zhang, , | Summary: Lepton flavor violation (LFV), observed conclusively in neutrino oscillations, remains a pivotal area of investigation due to its absence in the Standard Model (SM). Beyond the Standard Model (BSM) physics explores charged lepton flavor violation (CLFV), particularly through […]
