Environment-dependent mass splitting to suppress solar capture in the inelastic-doublet interpretation of the LZ event
Sudhakantha Girmohanta, Tae Hyun Jung
The inelastic electroweak-doublet interpretation of the recoil energy event reported by LUX-ZEPLIN faces strong constraints from solar capture. We propose an envir…
Majoron-driven spontaneous leptogenesis in type-II seesaw model
Eung Jin Chun, Tae Hyun Jung, Jin Sun
We investigate a minimal realization of spontaneous leptogenesis in the type-II seesaw model, where the lepton and Higgs asymmetries are generated as decay and inverse-decay proces…
Bipartite Solution to the Lithium Problem
Sougata Ganguly, Tae Hyun Jung, Tae-Sun Park +1
The primordial lithium problem remains a persistent motivation for new-physics modifications of Big Bang nucleosynthesis, yet the precision of the observed deuterium abundance now…
Revisiting QCD-induced little inflation with chiral density wave state and its implications on pulsar timing array gravitational-wave signals
Tae Hyun Jung, Seyong Kim, Jong-Wan Lee +2
We revisit QCD-induced little inflation in which the Universe begins with a large baryon chemical potential and undergoes a strong first-order QCD phase transition, generating an o…
Consistent fitting in big bang nucleosynthesis analysis
Sougata Ganguly, Tae Hyun Jung, Seokhoon Yun
The effective number of neutrino species, , serves as a key fitting parameter extensively employed in cosmological studies. In this work, we point out a fundamental in…
What happens when supercooling is terminated by curvature flipping of the effective potential?
Tomasz P. Dutka, Tae Hyun Jung, Chang Sub Shin
We explore the nature of a certain type of supercooled phase transition, where the supercooling is guaranteed to end due to the curvature of the finite-temperature effective potent…
Cogenesis by a sliding pNGB with symmetry non-restoration
Eung Jin Chun, Suruj Jyoti Das, Minxi He +2
We demonstrate that a pseudo-Nambu-Goldstone boson (pNGB) with an initial misalignment angle can drive successful spontaneous baryogenesis and serve as a dark matter (DM) candidate…
Finite modular majoron
Tae Hyun Jung, Junichiro Kawamura
We point out that the accidental symmetry can arise from a finite modular symmetry in the type-I seesaw. The finite modular symmetry is spontaneously broken in s…
Constraining MeV to 10 GeV majoron by Big Bang Nucleosynthesis
Sanghyeon Chang, Sougata Ganguly, Tae Hyun Jung +2
We estimate the Big Bang nucleosynthesis (BBN) constraint on the majoron in the mass range between to which dominantly decays into the standard model…
Leptogenesis driven by majoron
Eung Jin Chun, Tae Hyun Jung
We propose a leptogenesis scenario where baryon asymmetry generation is assisted by the kinetic motion of the majoron, , in the process of lepton-number violating inverse decays…
