Reconstruction of physics objects at the Circular Electron Positron Collider with Arbor

European Physical Journal C: Particles and Fields, 2018
After the Higgs discovery, precise measurements of the Higgs properties and the electroweak observables become vital for the experimental particle physics. A powerful Higgs/Z factory, the Circular Electron Positron Collider (CEPC) is proposed.

Notes on lattice observables for parton distributions: nongauge theories

Journal of High Energy Physics, 2020
We review recent theoretical developments concerning the definition and the renormalization of equal-time correlators that can be computed on the lattice and related to Parton Distribution Functions (PDFs) through a factorization formula.

Dilaton and massive hadrons in a conformal phase

Journal of High Energy Physics, 2022
As the number of fermion fields is increased, gauge theories are expected to undergo a transition from a QCD-like phase, characterised by confinement and chiral symmetry breaking, to a conformal phase, where the theory becomes scale-invariant at large ...

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.

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.

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

Probing $HZ\gamma$ and $H\gamma\gamma$ anomalous couplings in the process of $e^+e^- \to H\gamma$

, 2015
Rare decay of the Higgs boson is a powerful tool to probe new physics beyond the standard model. The rare decays occur through quantum loops in which the standard model and new physics contributions might cancel each other out. We consider a faked-no-new-

Toward High Precision Higgs-Boson Measurements at the International Linear e+e- Collider [PDF]

, 2005
This report reviews the properties of Higgs bosons in the Standard Model (SM) and its various extensions. We give an extensive overview about the potential of the ILC operated at centre-of-mass energies up to 1 TeV (including the gamma gamma option) for ...

QED corrections in B ¯ → K ¯ ℓ + ℓ − $$ \overline{B}\to \overline{K}{\mathrm{\ell}}^{+}{\mathrm{\ell}}^{-} $$ at the double-differential level

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.

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 $H_3\rightarrow H_1H_2$.
