Pseudo-Nambu-Goldstone inflation with symmetric waterfall fields
Hyun Min Lee, Adriana G. Menkara
We propose a hybrid inflation model where a pseudo-Nambu-Goldstone boson inflaton couples to waterfall scalar fields respecting a symmetry. We identify the phases for the…
pNGB Higgs Naturalness at a Tipping Point
Matthew McCullough, Adriana Menkara, Ennio Salvioni
In scenarios where the Higgs is viewed as a pseudo Nambu-Goldstone boson (pNGB) the question of naturalness finds itself, from a phenomenological perspective, at a tipping point be…
Towards self-consistent models for Inflation and Early Universe Cosmology
Adriana Menkara
In this PhD thesis we take smalls steps towards linking our knowledge of the Early Universe with our knowledge of particle physics. Chapters 3, 4 and 5 deal with Higgs inflation UV…
Inflation models with Peccei-Quinn symmetry and axion kinetic misalignment
Hyun Min Lee, Adriana G. Menkara, Myeong-Jung Seong +1
We propose a consistent framework with the Peccei-Quinn (PQ) symmetry for obtaining the initial condition for axion kinetic misalignment from inflation. We introduce a PQ co…
Peccei-Quinn Inflation at the Pole and Axion Kinetic Misalignment
Hyun Min Lee, Adriana G. Menkara, Myeong-Jung Seong +1
We propose a minimal extension of the Standard Model with the Peccei-Quinn (PQ) scalar field and explain the relic density of the QCD axion through the kinetic misalignment with a…
Higgs Inflation at the Pole
Simon Cléry, Hyun Min Lee, Adriana G. Menkara
We propose a novel possibility for Higgs inflation where the perturbative unitarity below the Planck scale is ensured by construction and the successful predictions for inflation a…
Graceful exit from inflation and reheating with twin waterfalls
Hyun Min Lee, Adriana Menkara
We study the hybrid inflation with a pseudo-Nambu-Goldstone boson inflaton and two waterfall scalar fields. The symmetry for the waterfall fields keeps inflaton potential fla…
The lepton portals for muon , boson mass and dark matter
Seong-Sik Kim, Hyun Min Lee, Adriana G. Menkara +1
We propose a novel model which extends the Standard Model (SM) by introducing a gauge symmetry. In this model, a dark Higgs doublet and a Higgs bi-doublet can c…
The lepton portals for muon , boson mass and dark matter
Seong-Sik Kim, Hyun Min Lee, Adriana G. Menkara +1
We propose a novel model for lepton flavor and dark matter based on the gauge symmetry and vector-like leptons in its fundamental representations. We introduce a dark $SU…
Pseudo-Nambu-Goldstone inflation with twin waterfalls
Hyun Min Lee, Adriana Menkara
We propose a pseudo-Nambu-Goldstone inflation where twin waterfall fields coupled to the inflaton are responsible for the graceful exit from inflation by a waterfall transition. In…
Reheating and Dark Matter Freeze-in in the Higgs- Inflation Model
Shuntaro Aoki, Hyun Min Lee, Adriana G. Menkara +1
We study the post-inflationary dynamics for reheating and freeze-in dark matter in the Higgs- inflation model. Taking the perturbative approach for reheating, we determine the…
Inflation and Supersymmetry Breaking in Higgs- Supergravity
Shuntaro Aoki, Hyun Min Lee, Adriana G. Menkara
We propose a new construction of the supergravity inflation as an UV completion of the Higgs- inflation. In the dual description of -supergravity, we show that there appe…
Cosmology of Linear Higgs-Sigma Models with Conformal Invariance
Hyun Min Lee, Adriana G. Menkara
We consider general linear Higgs-sigma models as ultra-violet completions of the Higgs inflation. We introduce general higher curvature terms beyond Einstein gravity and recast the…
Flux-mediated Dark Matter
Yoo-Jin Kang, Hyun Min Lee, Adriana G. Menkara +1
We propose a new mechanism to communicate between fermion dark matter and the Standard Model (SM) only through the four-form flux. The four-form couplings are responsible for the r…
