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 ...

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 ...

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.

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 ...

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

In the original version, the bounds given in Eqs. (87a) and (87b) on the contribution to the early-time optical depth, (15,30), contained a numerical error in deriving the 95th percentile from the Monte Carlo samples. The corrected 95% upper bounds are: τ(15,30) < 0:018 (lowE, flat τ(15, 30), FlexKnot), (1) τ(15, 30) < 0:023 (lowE, flat knot, FlexKnot):

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

Scattering amplitudes of Kaluza-Klein strings and extended massive double-copy

Journal of High Energy Physics, 2022
We study the scattering amplitudes of massive Kaluza-Klein (KK) states of open and closed bosonic strings under toroidal compactification. We analyze the structure of vertex operators for the KK strings and derive an extended massive KLT-like relation ...
