Composite Hybrid Inflation: Dilaton and Waterfall Pions
Giacomo Cacciapaglia, Dhong Yeon Cheong, Aldo Deandrea +2
We investigate the possibility that inflation originates from a composite field theory, in terms of an effective chiral Lagrangian involving a dilaton and pions. The walking dynami…
Cosmic Birefringence by Dark Photon
Sung Mook Lee, Dong Woo Kang, Jinn-Ouk Gong +3
We study the kinetic mixing between the cosmic microwave background (CMB) photon and the birefringent dark photon. These birefringent dark photon may exist in parity-violating dark…
DeeLeMa: Missing information search with Deep Learning for Mass estimation
Kayoung Ban, Dong Woo Kang, Tae-Geun Kim +2
We introduce DeeLeMa, a deep learning-based network for the analysis of energy and momentum in high-energy particle collisions. This novel approach is specifically designed to addr…
Primordial Black Holes as a Factory of Axions: Extragalactic Photons from Axions
Yongsoo Jho, Tae-Geun Kim, Jong-Chul Park +2
Primordial black holes (PBHs) are significant sources of axions and axion-like particles (ALPs), provided their Hawking temperature exceeds the particles' masses. Given the predomi…
Phenomenological implications on a hidden sector from the Festina Lente bound
Kayoung Ban, Dhong Yeon Cheong, Hiroshi Okada +3
We apply the Festina Lente (FL) bound on a hidden sector with gauge symmetries. Since the FL bound puts a lower bound on masses of particles charged under the gauge s…
The Inflaton that Could : Primordial Black Holes and Second Order Gravitational Waves from Tachyonic Instability induced in Higgs- Inflation
Dhong Yeon Cheong, Kazunori Kohri, Seong Chan Park
The running of the Higgs self coupling may lead to numerous phenomena in early universe cosmology. In this paper we introduce a scenario where the Higgs running induces turns in th…
