The role of triangle singularity in the decay
Wei Wang, Dazhuang He, Xuan Luo
The triangle singularity interpretation of the \replyhe{} observed by the COMPASS Collaboration has been widely accepted. In this work, we investigate the triangle mecha…
Anomaly-free axion-like particle in Nelson-Barr models
Mohammad Aghaie, Ryoma Masuda, Ryosuke Sato
We study Nelson--Barr models with a discrete symmetry that solve the strong CP problem through spontaneous CP violation, and show that they naturally predict a light axion-li…
Qubits for Dark Matter Hunting
Takeo Moroi
An introductory review is provided for those who are interested in exploring applications of qubits and other quantum excitations to the detection of dark matter (and any other phy…
Dielectric Response for Light Dark Matter Direct Detection Beyond the Longitudinal Approximation
Zheng-Liang Liang, Lei Wu, Wen-Na Yang +2
The dielectric formalism for light dark matter--electron scattering in semiconductors has, to date, employed only the longitudinal dielectric function , with the transverse re…
A window for the mixed same-sign signature in the type-II seesaw models
Cheng-Wei Chiang
The mass splitting between the doubly and singly charged members of the Higgs triplet of the type-II seesaw model is usually treated as a free parameter in the collider literature.…
A Hydrogen-Like Model for Pion and Kaon Masses Based on Dirac Quark-Hamiltonians and Numerical Methods
Zhenhua Ning, A. S. Davuluru, H. Raposo +1
We consider a relativistic hydrogen-like model for meson mass spectra. The model is based on a Lagrangian with a new general Yang-Mills symmetry. The strong interactions involve a…
