Higgs boson decay to charmonia via c-quark fragmentation

open access: yesJournal of High Energy Physics, 2022
We calculate the decay branching fractions of the Higgs boson to J/ψ and η c via the charm-quark fragmentation mechanism for the color-singlet and color-octet states in the framework of non-relativistic QCD.

Searching for heavy leptophilic Z′: from lepton colliders to gravitational waves

open access: yesJournal of High Energy Physics, 2023
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.

Quark and gluon contents of a lepton at high energies

open access: yesJournal of High Energy Physics, 2022
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 should thus be formulated in terms of the EW ...

Light-cone distribution amplitudes of a light baryon in large-momentum effective theory

open access: yesJournal of High Energy Physics, 2023
Momentum distributions of quarks/gluons inside a light baryon in a hard exclusive process are encoded in the light-cone distribution amplitudes (LCDAs).

Transverse-momentum-dependent wave functions and soft functions at one-loop in large momentum effective theory

open access: yesJournal of High Energy Physics, 2022
In large-momentum effective theory (LaMET), the transverse-momentum-dependent (TMD) light-front wave functions and soft functions can be extracted from the simulation of a four-quark form factor and equal-time correlation functions.

Analyzing Cross-Cultural Studies of Arguing in the Globalized World [PDF]

open access: yesФилософия и космология, 2020
Cosmology is often viewed as the study of the physical universe. However, it does not mean that the issues of philosophy of cosmology relate only to research fields of physics, astronomy, astrophysics, and mathematics.
