Nuclear Recoils from Invisible Neutron-Pair Annihilation and the LZ event

Junseok Lee, Fuminobu Takahashi, Yu-Dai Tsai

Two bound neutrons can annihilate into a single invisible scalar carrying baryon number two, producing a monochromatic nuclear recoil. Pair removal connects the ground states…

Axion Isocurvature Perturbations Survive the Scaling Evolution of Axion Domain Walls

Naoya Kitajima, Junseok Lee, Kai Murai +2

We revisit the evolution of axion domain walls seeded by inflationary fluctuations. In our previous work, we showed that such domain-wall networks retain superhorizon correlations…

Arithmetic Symmetry in Ideal Prouhet-Tarry-Escott Solutions

Yu-Dai Tsai, Junseok Lee, Fuminobu Takahashi

Motivated in part by anomaly cancellation for integral charge spectra in chiral gauge theory, we study the symmetric locus in the ideal degree-three Prouhet-Tarry-Escott problem. A…

Domain-wall Quintessence

Nobufusa Kobayashi, Yuichiro Tada, Fuminobu Takahashi +1

We investigate a dark energy model driven by a planar domain-wall-like structure with a thickness comparable to, or larger than, the current Hubble radius, focusing on its intrinsi…

Multi-field oscillons/I-balls in the Friedberg-Lee-Sirlin model

Kai Murai, Tatsuya Ogawa, Fuminobu Takahashi

We study oscillon/I-ball solutions in a real scalar version of the Friedberg-Lee-Sirlin (FLS) model. Using the multiple-scale analysis, we derive the conditions for oscillon soluti…

Number Theory in Quantum Physics: Minicharged Particles and the Prouhet-Tarry-Escott Problem

Junseok Lee, Fuminobu Takahashi, Yu-Dai Tsai

In quantum gauge theories, anomaly cancellation severely restricts the allowed patterns of chiral charges. Here we show that, in a phenomenologically motivated framework for light…
