We study a two-component pseudo-Nambu-Goldstone-boson (pNGB) dark matter (DM) model motivated by boosted dark matter (BDM). The model is based on a complex scalar field charged under a dark $\text{U}(1)_V$ gauge symmetry, with a softly broken global $\text{SU}(3)_g$ symmetry that is spontaneously …

Delivered my first physics presentation in Japanese on ways to probe pseudo-Nambu-Goldstone boson dark matter at the 131st JPS Kyushu Branch Meeting.
Completed Kyushu University's Preparing Future Faculty Program and earned certification in Course Design in Higher Education (CDHE).
Presented a talk on probing pseudo-Nambu-Goldstone boson dark matter at the 29th International Summer Institute on Phenomenology of Elementary Particle Physics and Cosmology.
This study explores a dark matter model in which a pseudo-Nambu-Goldstone boson arises as a viable dark matter candidate from the spontaneous and soft breaking of global $\mathrm U(1)$ symmetries and stabilized by a residual $\mathbb{Z}_3$ discrete symmetry. The model introduces three complex scalar …
Presented a poster on pseudo-Nambu-Goldstone boson dark matter and received a Best Poster Honorable Mention at HPNP2025.
With Leonardo Laksamana, shared our MEXT scholarship journey at the Kyushu University Virtual Fair.
