Perturbative Higgs CP violation, unitarity and phenomenology [PDF]
Phys. Rev. D 95, 015018 (2017), 2016 Perturbative probability conservation provides a strong constraint on the presence of new interactions of the Higgs boson. In this work we consider CP violating Higgs interactions in conjunction with unitarity constraints in the gauge-Higgs and fermion-Higgs sectors.

On the Weyl gravity extension of Higgs inflation [PDF]
arXiv, 2022 We consider the embedding of Higgs inflation with a non-minimal coupling into the Weyl gravity. In this model, the effective current-current interactions from the heavy Weyl gauge field cancel the non-canonical Higgs kinetic term in Einstein frame, so the unitarity problem of the original Higgs inflation becomes less severe. For a simple case where the

Directly probing the Higgs-top coupling at high scales
Physics Letters B, 2022 We explore the sensitivity to new physics for the coupling of the Higgs boson (h) and top quark (t) at high energy scales with the process pp→tt¯h at the high-luminosity LHC.

Journal of High Energy Physics, 2020 We present a detailed analysis of QED corrections to B ¯ → K ¯ ℓ + ℓ − $$ \overline{B}\to \overline{K}{\mathrm{\ell}}^{+}{\mathrm{\ell}}^{-} $$ decays at the double-differential level.

European Physical Journal C: Particles and Fields, 2023 The recent introduction of machine learning techniques, especially normalizing flows, for the sampling of lattice gauge theories has shed some hope on improving the sampling efficiency of the traditional hybrid Monte Carlo (HMC) algorithm.

The Heavy Higgs Decay Effect and Its Impact on Higgs Data Fitting in NMSSM [PDF]
arXiv, 2015 Besides the loop contribution and the coupling changing, heavy Higgs decaying to 125GeV Higgs is another important effect in Higgs property measurement in the models that have extend Higgs sector. Such heavy Higgs decay effect contain more than one sources, such as $A\rightarrow Zh$, $H\rightarrow hh$, $A_2\rightarrow A_1h$, and $H_3\rightarrow H_1H_2$.

ATLAS physics results (not Higgs) [PDF]
EPJ Web of Conferences, 2015 These proceedings give a review of some of the non-Higgs physics results from ATLAS. The topics covered include Standard Model, exotics and SUSY. Rather than summarizing the very large number of results available in these areas, a few analyses are picked out to emphasize some important common themes for LHC physics. The first theme is the importance of

Two paths towards precision at a very high energy lepton collider
Journal of High Energy Physics, 2021 We illustrate the potential of a very high energy lepton collider (from 10 to 30 TeV center of mass energy) to explore new physics indirectly in the vector boson fusion double Higgs production process and in direct diboson production at high energy ...

Parity doubling as a tool for right-handed current searches
Journal of High Energy Physics, 2018 The V-A structure of the weak interactions leads to definite amplitude hierarchies in exclusive heavy-to-light decays mediated by b → (d, s)γ and b→d,sℓℓ¯ $$ b\to \left(d,\ s\right)\ell \overline{\ell} $$. However, the extraction of right-handed currents
