Open AccessSearching for heavy leptophilic Z′: from lepton colliders to gravitational waves
We study the phenomenology of leptophilic Z′ gauge bosons at the future high-energy e+e− and μ+μ− colliders, as well as at the gravitational wave observatories. The leptophilic Z′ model, although well-motivated, ...

Open AccessA guide to diagnosing colored resonances at hadron colliders
We present a comprehensive study on how to distinguish the properties of heavy dijet resonances at hadron colliders. A variety of spins, chiral couplings, charges, and QCD color representations are considered....

Open AccessRight-handed Dirac and Majorana neutrinos at Belle II
We assess the ability of the Belle II experiment to probe the Dirac or Majorana nature of a massive right-handed neutrino (RHN) N in the MeV to GeV mass range. We consider the production and decay of RHNs to proc...

Open AccessHeavy neutral leptons at the Electron-Ion Collider
The future Electron-Ion Collider (EIC) at Brookhaven National Laboratory, along with its primary capacity to elucidate the nuclear structure, will offer new opportunities to probe physics beyond the Standard M...

Open AccessHiggs boson decay to charmonia via c-quark fragmentation
We calculate the decay branching fractions of the Higgs boson to J/ψ and ηc via the charm-quark fragmentation mechanism for the color-singlet and color-octet states in the framework of non-relativistic QCD. The d...

Open AccessLeptonic scalars and collider signatures in a UV-complete model
We study the non-standard interactions of neutrinos with light leptonic scalars (ϕ) in a global (B − L)-conserved ultraviolet (UV)-complete model. The model utilizes Type-II seesaw motivated neutrino interactions...

Open AccessQuark and gluon contents of a lepton at high energies
In high-energy leptonic collisions, such as at a multi-TeV muon collider, the collinear splittings of the electroweak (EW) gauge bosons and leptons are the dominant phenomena, and the scattering processes shou...

Open AccessPrecision test of the muon-Higgs coupling at a high-energy muon collider
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 ...

Open AccessElectroweak phase transition with an SU(2) dark sector
We consider a non-Abelian dark SU(2)D model where the dark sector couples to the Standard Model (SM) through a Higgs portal. We investigate two different scenarios of the dark sector scalars with Z2 symmetry, wit...

Open AccessComparative studies of 2HDMs under the Higgs boson precision measurements
We perform comparative studies for four types of the two Higgs Doublet Models (2HDMs) under the precision measurements of the Standard Model (SM) Higgs observables at the proposed Higgs factories. We explore t...

Open AccessType-I 2HDM under the Higgs and electroweak precision measurements
We explore the extent to which future precision measurements of the Standard Model (SM) observables at the proposed Z-factories and Higgs factories may have impacts on new physics beyond the Standard Model, as il...

Open AccessScalar and tensor neutrino interactions
We constrain general Dirac neutrino interactions based on the Standard Model Effective Field Theory framework extended with right-handed neutrinos N (SMNEFT) using deep inelastic and coherent elastic neutrino sca...

Open AccessLeptonic scalars at the LHC
We explore the collider prospects of neutrino non-standard interaction with a Standard Model (SM) gauge-singlet leptonic scalar ϕ carrying two units of lepton-number-charge. These leptonic scalars are forbidden f...

Open AccessNonstandard neutrino interactions at COHERENT, DUNE, T2HK and LHC
We study how nonstandard neutrino interactions (NSI) may be probed by a combination of coherent elastic neutrino-nucleus scattering, neutrino oscillation and collider data, from COHERENT, DUNE, T2HK and the hi...

Open AccessDark matter blind spots at one-loop
We evaluate the impact of one-loop electroweak corrections to the spin-independent dark matter (DM) scattering cross-section with nucleons (σSI), in models with a so-called blind spot for direct detection, where ...

Future precision measurements of the Standard Model (SM) parameters at the proposed Z-factories and Higgs factories may have significant impacts on new physics beyond the Standard Model in the electroweak sector....

Open AccessElectroweak splitting functions and high energy showering
We derive the electroweak (EW) collinear splitting functions for the Standard Model, including the massive fermions, gauge bosons and the Higgs boson. We first present the splitting functions in the limit of u...

Open AccessMeasuring the CP property of Higgs coupling to tau leptons in the VBF channel at the LHC
We study the prospects of measuring the CP property of the Higgs (h) coupling to tau leptons using the vector boson fusion (VBF) production mode at the high-luminosity LHC. Utilizing the previously proposed angle...
