Bubble-assisted Leptogenesis
Eung Jin Chun, Tomasz P. Dutka, Tae Hyun Jung +2
We explore the possibility of embedding thermal leptogenesis within a first-order phase transition (FOPT) such that RHNs remain massless until a FOPT arises. Their sudden and viole…
Primordial black holes from bubble collisions during a first-order phase transition
Tae Hyun Jung, Takemichi Okui
We study the possibility of production of primordial black holes (PBHs) from bubble collisions during a first-order phase transition. While typical colliding bubbles are small and…
Composite neutrinos and the QCD axion: baryogenesis, dark matter, small Dirac neutrino masses, and vanishing neutron EDM
Sabyasachi Chakraborty, Tae Hyun Jung, Takemichi Okui
We consider a chiral gauge theory from which light composite Dirac neutrinos dynamically emerge, augmented by a QCD axion to solve the strong CP problem. We show that an interplay…
A solar origin of the XENON1T excess without stellar cooling problems
Sabyasachi Chakraborty, Tae Hyun Jung, Vazha Loladze +2
Solar interpretations of the recent XENON1T excess events, such as axion or dark photon emissions from the sun, are thought to be at odds with stellar cooling bounds from the horiz…
Dark matter filtering-out effect during a first-order phase transition
Dongjin Chway, Tae Hyun Jung, Chang Sub Shin
If the mass of dark matter is generated from a cosmological phase transition involving the nucleation of bubbles, the corresponding bubble walls can filter out dark matter particle…
Spontaneous Twin Symmetry Breaking
Tae Hyun Jung
We consider a twin Higgs scenario where the twin symmetry is broken spontaneously, not explicitly. This scenario provides an interesting interpretation of the Higgs metastabi…
