Cosmic Millicharge Background and Reheating Probes
Xucheng Gan, Yu-Dai Tsai
We demonstrate that the searches for dark sector particles can provide probes of reheating scenarios, focusing on the cosmic millicharge background produced in the early universe.…
Cosmologically Varying Kinetic Mixing
Xucheng Gan, Di Liu
The portal connecting the invisible and visible sectors is one of the most natural explanations of the dark world. However, the early-time dark matter production via the portal fac…
Millicharged Relics Reveal Massless Dark Photons
Asher Berlin, Jeff A. Dror, Xucheng Gan +1
The detection of massless kinetically-mixed dark photons is notoriously difficult, as the effect of this mixing can be removed by a field redefinition in vacuum. In this work, we s…
Electroweak Sphaleron with Dimension-6 Operators
Xucheng Gan, Andrew J. Long, Lian-Tao Wang
New physics at the TeV scale can affect the dynamics of the electroweak phase transition in many ways. In this note, we evaluate its impact on the rate of baryon-number violation v…
