Self-Interacting Dark Matter and the Origin of Ultra-Diffuse Galaxies NGC1052-DF2 and -DF4

Daneng Yang, Hai-Bo Yu, Haipeng An

Observations of ultra-diffuse galaxies NGC 1052-DF2 and -DF4 show they may contain little dark matter, challenging our understanding of galaxy formation. Using controlled N-body si…

Determining Strong Phase of $a_{1}$ Meson Decay Amplitude using $W \to ν τ (\to ν a_{1} (\to π^{\mp} π^{\mp} π^{\pm}))$ Process

Kaoru Hagiwara, Hiroyuki Ishida, Toshifumi Yamada +1

To measure the helicity of a spin-1 meson from the triple vector product of the three-momenta of its decay products, one needs information about the strong phase of the decay ampli…
