Probing Neutrinophilic Axion-Like Particles in Tritium Beta Decay
Yi Chung, Florian Goertz, Maya Hager +1
We investigate the prospects for constraining neutrinophilic axion-like particles via measurements of the tritium beta decay spectrum, as performed by the KATRIN experiment and its…
Two coincidences are a clue: Probing a GeV-scale dark QCD sector
Yi Chung
The similarity between the dark matter and baryon energy densities suggests an existence of a dark sector analogous to QCD. In addition, small-scale structure anomalies can be addr…
Third-generation-philic Hidden Naturalness
Yi Chung, Florian Goertz
We present a solution to the electroweak hierarchy problem, where the relevant new particles are third-generation-philic and hidden in SM processes with third-generation fermions.…
Dynamical origin of Type-I Seesaw with large mixing
Yi Chung
We investigate Type-I Seesaw models where the right-handed neutrino masses are dynamically generated by strong interactions. Using horizontal gauge symmetry as the source of strong…
Naturalness-motivated composite Higgs model for generating the top Yukawa coupling
Yi Chung
The large top Yukawa coupling results in the top quark contributing significantly to the quantum correction of the Higgs mass term. Traditionally, this effect is canceled by the pr…
The Hierarchy Problem and the Top Yukawa
Andreas Bally, Yi Chung, Florian Goertz
In this talk, an alternative to top partner solutions and its consequences on phenomenology are discussed. The hierarchy problem from the top loop contribution is solved by mitigat…
