Jing Shu

Shu Jing is a distinguished professor in the school of physics of Peking University. In 2012, he was selected as young overseas high-level talent and returned to China. In 2019, for his leading research on the breaking of fundamental symmetries in particle physics and cosmology, he received the Asian Achievement Award from the Global Chinese Society of Physics and Astronomy (Robert T. Poe Prize), and he is the youngest recipient of the award so far. In 2020, he was granted by the National Natural Science Foundation for Distinguished Young Scholars.

Jing Shu has always focused his research on particle physics and cosmology. According to the INSPIRE high-energy physics database, 76 papers have been published till April of 2022, including 12 papers in Physical Review Letters (PRL) (2 papers selected as the Editor’s Suggestion) and 1 paper in Nature Astronomy. The total citation is more than 4,100 times. Due to his significant progress in the origin of mass of fundamental particles, ultra-light dark matter detection, scattering amplitude and effective field theory, he has been invited to give plenary talks at many international conferences, such as SUSY2015, BLV2015, HEFT2019, HEFT2021, etc.

Abstract

A cosmological first-order phase transition is expected to produce a stochastic gravitational wave background. If the phase transition temperature is on the MeV scale, the power spectrum of the induced stochastic gravitational waves peaks around nanohertz frequencies, and can thus be probed with high-precision pulsar timing observations. We search for such a stochastic gravitational wave background with the latest data set of the Parkes Pulsar Timing Array...

Constraining Cosmological Phase Transitions with the Parkes Pulsar Timing Array (PhysRevLett.127.251303, 2021)

Abstract

We derive the generalized partial wave expansion for N (M) scattering amplitude in terms of spinor helicity variables. The basis amplitudes of the expansion with definite angular momentum j consist of the Poincar´e Clebsch-Gordan coefficients. Moreover, we obtain a series of selection rules that restrict the anomalous dimension matrix of effective operators and how effective operators contribute to some 2 (N) amplitudes at the loop level....

Partial Wave Amplitude Basis and Selection Rules in Effective Field Theories (PhysRevLett.126.011601, 2021)

Abstract

We propose boosted dark matter (BDM) as a possible explanation for the excess of keV electron recoil events observed by XENON1T. BDM particles have velocities much larger than those typical of virialized dark matter, and, as such, BDM-electron scattering can naturally produce keV electron recoils. We show that the required BDM-electron scattering cross sections can be easily realized in a simple model with a heavy vector mediator...

Boosted Dark Matter Interpretation of the XENON1T Excess (Phys. Rev. Lett. 125, 161804, 2020)

Abstract

With high spatial resolution, polarimetric imaging of a supermassive black hole, like M (87 star) or Sgr A(star), by the Event Horizon Telescope can be used to probe the existence of ultralight bosonic particles, such as axions. Such particles can accumulate around a rotating black hole through the superradiance mechanism, forming an axion cloud...
