Giant Dipole Resonance in A ~ 144 mass region

EPJ Web of Conferences, 2013
Exclusive measurement of giant dipole resonance (GDR) γ rays has been performed in 144Sm nucleus which was populated at near barrier energy using the heavy ion reaction of 28Si beam on 116Cd target. GDR γ rays were detected in coincidence with low energy

Electron-ion equilibration in superheated gold

Nature Communications
Electron-ion equilibration dynamics in samples driven into superheated states with multi-eV electron temperatures represent a fundamental process in nonequilibrium physics.

Coherent X-rays reveal the influence of cage effects on ultrafast water dynamics

Nature Communications, 2018
The dynamics of liquid water is rich due to its complex, highly disordered hydrogen-bond network, which hasn’t been fully understood. Perakis et al. measure water dynamics at sub-100 fs and show that it cannot be described by simple thermal motion due to

Infrared freeze-in of magnetic dipole dark matter

Journal of High Energy Physics
We propose a novel mechanism for the cosmological production of keV–GeV mass dark matter that interacts with the Standard Model through a small effective magnetic dipole moment.

The non-relativistic effective field theory of dark matter-electron interactions

Journal of High Energy Physics
Electronic excitations in atomic, molecular, and crystal targets are at the forefront of the ongoing search for light, sub-GeV dark matter (DM). In many light DM-electron interactions the energy and momentum deposited is much smaller than the electron ...

Forty years of BEPC/BES

Nuclear Physics B
This paper reviews the discovery of the J particle and examines its impact on high-energy physics in China. Charm physics emerged as the primary research focus of the Beijing Electron-Positron Collider (BEPC/BES) and its upgraded successor, BEPCII/BESIII.
