There is a recent growing interest in detecting gravitational waves (GWs) via lunar seismic measurements. It requires a precise understanding of the Moon’s response to passing GWs but previous studies derived two seemingly different response functions—one using a field-theory approach and the other based on tidal forces—raising questions about their equivalence. Here, we analytically and...
Red giants (RGs) efficiently capture dark matter (DM) through elastic scattering with stellar nuclei. Once accumulated in the helium core, the DM population can become self-gravitating and collapse, injecting energy through scattering and (when relevant) delayed annihilation. This localized heating can trigger a premature helium flash, reducing the luminosity at the tip of the RG branch. By...
We investigate whether collider experiments can reach the quantum limit of precision, defined by the quantum Fisher information (QFI), using only classical observables such as particle momenta. As a case study, we focus on the $\tau^+\tau^-$ system and the decay channel $\tau \to \pi \nu$, which offers maximal spin-analyzing power and renders the decay a projective measurement.
We develop a...
Dark matter is the dominant matter in the Universe while its particle nature is still unknown. In this talk, I will introduce two major scenarios of dark matter: Axion dark matter and WIMP (Weakly Interactive Massive Particle) and show how radio telescopes can search and put constraints on their parameters. The first one is Axion, which is a compelling dark matter candidate of increasing...
