Late-time Quantum Vacuum Decay and its Cosmological Implications
Yang Bai, Sida Lu, Nicholas Orlofsky
The existence of a landscape of metastable vacua raises the possibility that our Universe may have undergone quantum vacuum decay at late times. This work explores how such a trans…
Sub-GeV Right-Handed Neutrino as a Probe of Neutrino Mass Generation in the Minimal Left-Right Symmetric Model
Gang Li, Ying-Ying Li, Sida Lu +1
The minimal left-right symmetric model (mLRSM) provides an elegant and testable framework for addressing the origin of neutrino masses. We examine the constraints on the sub-GeV ri…
Dark Photon Polarimetry
Fiesta Ting Yan Leung, Tao Liu, Sida Lu +3
We propose detecting dark photons (DP), a major candidate for wave dark matter, through polarimetry. The DP can modify Maxwell's equations due to its kinetic mixing with regular ph…
Gravitational Waves From Dark Binaries With Finite-Range Dark Forces
Yang Bai, Sida Lu, Nicholas Orlofsky
This paper calculates the stochastic gravitational wave background from dark binaries with finite-range attractive dark forces, complementing previous works which consider long-ran…
Gravitational Waves From More Attractive Dark Binaries
Yang Bai, Sida Lu, Nicholas Orlofsky
The detection of gravitational waves (GWs) has led to a deeper understanding of binaries of ordinary astrophysical objects, including neutron stars and black holes. In this work, w…
Challenges in Interpreting the NANOGrav 15-Year Data Set as Early Universe Gravitational Waves Produced by ALP Induced Instability
Michael Geller, Subhajit Ghosh, Sida Lu +1
In this paper, we study a possible early universe source for the recent observation of a stochastic gravitational wave background at the NANOGrav pulsar timing array. The source is…
