I will discuss the high-precision theoretical prediction on Higgs pair production at the LHC and the constraint on the Higgs self-coupling.
I will talk about our recent work on electroweak corrections to Higgs boson production and decay.
In this report, I will first introduce the puzzles in semileptonic B meson decays, and then discuss the important role that studies of the fine structure of light hadrons play in addressing this puzzle.
The decay into bottom quarks is the dominant decay channel of a Standard Model Higgs boson. Its precise theory description is crucial for extracting the bottom quark Yukawa coupling and mass from experimental measurements. We report on the status of the first next-to-next-to-next-to QCD calculation in Higgs effective theory retaining the mass dependence of the bottom quark in the final states....
Ultra-high-energy cosmic rays (UHECR) scattering off the cosmic relic neutrino background have recently gained renewed interest in the literature. Current data suggest that (UHECR) are predominantly made of heavy nuclei. Similar to the coherent elastic neutrino-nucleus scattering (CE$\nu$NS) observed at low-energy neutrino experiments, the cross section of heavy nucleus scattering off relic...
In this work we study the prospect of detecting light scalars at the FASER, Mathusla codex-B etc. We develop the general formalism for the scalar production and decay from mesons with PP collision, given modified couplings of the scalars to the SM particles, as well as summarizing the relevant GeV-scale experiment constraints. We then analyze the reaches of light scalars in the large tan𝛽...
