Precision test of the muon-Higgs coupling at a high-energy muon collider
Journal of High Energy Physics, 2021 We explore the sensitivity of directly testing the muon-Higgs coupling at a high-energy muon collider. This is strongly motivated if there exists new physics that is not aligned with the Standard Model Yukawa interactions which are responsible for the ...

Topological Equivalence Theorem and Double-Copy for Chern–Simons Scattering Amplitudes
Research, 2023 We study the mechanism of topological mass generation for 3-dimensional Chern–Simons gauge theories and propose a brand-new topological equivalence theorem to connect scattering amplitudes of the physical gauge boson states to that of the transverse ...

Weak decays of doubly heavy baryons: multi-body decay channels
European Physical Journal C: Particles and Fields, 2018 The newly-discovered $$\Xi _{cc}^{++}$$ Ξcc++ decays into the $$ \Lambda _{c}^+ K^-\pi ^+\pi ^+$$ Λc+K-π+π+ , but the experimental data has indicated that this decay is not saturated by any two-body intermediate state.

Meridian Circle Astrometry at the U. S. Naval Observatory
Cahiers François Viète, 2023 For 150 years meridian circles have played an essential part in the mission of the U. S. Naval Observatory (USNO) in its dual role as a naval observatory, in support of celestial navigation, and as a national observatory, improving the celestial ...

How Dark Matter Came to Matter [PDF]
, 2017 The history of the dark matter problem can be traced back to at least the 1930s, but it was not until the early 1970s that the issue of 'missing matter' was widely recognized as problematic.

Radiative decays of the Higgs boson to a pair of fermions
Journal of High Energy Physics, 2017 We revisit the radiative decays of the Higgs boson to a fermion pair h → f f ¯ γ $$ h\to f\overline{f}\gamma $$ where f denotes a fermion in the Standard Model (SM). We include the chirality-flipping diagrams via the Yukawa couplings at the order O y f 2

Reconstruction of the event vertex in the PandaX-III experiment with convolution neural network
Journal of High Energy Physics, 2023 The PandaX-III experiment uses a high-pressure xenon gaseous time projection chamber (TPC) to search for the neutrinoless double beta decay (0νββ) of 136Xe. The absence of the vertex position in the electron drift direction at which the event takes place

Modelling gravitational waves from precessing black-hole binaries: Progress, challenges and prospects [PDF]
, 2013 The inspiral and merger of two orbiting black holes is among the most promising sources for the first (hopefully imminent) direct detection of gravitational waves (GWs), and measurements of these signals could provide a wealth of information about ...
