This study explores the production of charged Higgs particles through photon-photon collisions within the context of the Two Higgs Doublet Model,including one-loop-level scattering amplitudes of electroweak and QED ra...
Neutral triple gauge couplings(nTGCs)are absent in the Standard Model(SM)and at the dimension-6 level in the Standard Model Effective Field Theory(SMEFT),arising first from dimension-8 operators.As such,they provide a...

We present a comprehensive analytic calculation of the next-to-next-to-leading order QCD■EW corrections to Z-boson pair production at electron-positron colliders.The two-loop master integrals essential to this calcul...
In this study,we explore the potentials of dipole operators and four-fermion operators at low-energy lepton colliders such as Belle Ⅱ and the Super Tau Charm Facility(STCF).We utilize high-dimension operators to char...

Within the framework of nonrelativistic-QCD factorization,we calculate both the next-to-leading-order relativistic and QCD corrections to prompt J/ψpair production,with feed-down fromψ(2S)mesons,via photon-photon co...

We present one-loop contributions for h→ℓℓγ with ℓ=νe,μ,τ,e,μ and e−e+→hγ in the U(1)_(B−L) extension of the standard model. In the phenomenological results, the signal strengths for h→ℓℓγ at the Large Hadro...

In this study,we reanalyze the top-quark pair production at next-to-next-to-leading order(NNLO)in quantum chromodynamics(QCD)at future e^(+)e^(−)colliders using the Principle of Maximum Conformality(PMC)method.The PMC...
Accessing a full image of the inner content of hadrons represents a central endeavour of modern particle physics,with the main scientific motivation to investigate the strong interaction binding the visible matter.On ...

We re-examine the jet probes of the nucleon spin and flavor structures.We find for the first time that the time-reversal odd(T-odd)component of a jet,conventionally thought to vanish,can survive due to the non-perturb...
