Study of Semileptonic B⟶DPℓ+νℓ Decays Based on the SU(3) Flavor Symmetry
Advances in High Energy Physics, Volume 2025, Issue 1, 2025.Decays B⟶DPℓ+νℓ(ℓ = e, μ, τ) with the nonresonance, the charmed vector resonances, the charmed scalar resonances, and the charmed tensor resonances are explored by using the SU(3) flavor symmetry approach. Firstly, the decay amplitudes of different modes are related by the SU(3) flavor symmetry.

Probing the transversity spin structure of a nucleon in neutrino-production of a charmed meson
EPJ Web of Conferences, 2016 Including O(mc) terms in the coefficient functions and/or O(mD) twist 3 contributions in the heavy meson distribution amplitudes leads to a non-zero transverse amplitude for exclusive neutrino production of a D pseudoscalar charmed meson on an ...

Electromagnetic structure and weak decay of pseudoscalar mesons in a light-front QCD-inspired model
, 2005 We study the scaling of the $^3S_1-^1S_0$ meson mass splitting and the pseudoscalar weak decay constants with the mass of the meson, as seen in the available experimental data.

Incompleteness of complete pseudoscalar-meson photoproduction [PDF]
Physical Review C, 2013 [Background] A complete set is a minimum set of observables which allows one to determine the underlying reaction amplitudes unambiguously. Pseudoscalar-meson photoproduction from the nucleon is characterized by four such amplitudes and complete sets involve single- and double-polarization observables.

Tensor Condensate Accompanied by Chiral Transition in a Strong Magnetic Field
Advances in High Energy Physics, Volume 2025, Issue 1, 2025.We investigate tensor condensates and chiral condensates in the (2 + 1)‐flavor Nambu–Jona–Lasinio model at finite temperature and density in the presence of a strong magnetic field. The emergence of the tensor condensate is attributed to the four‐fermion interaction.

Physics Letters B, 2022 We carry out the first lattice QCD derivation of the mixing energy and the mixing angle of the pseudoscalar charmonium and glueball on two gauge ensembles with Nf=2 degenerate dynamical charm quarks. The mixing energy is determined to be 49(6) MeV on the

Scaling test of quenched Wilson twisted mass QCD at maximal twist
, 2005 We present the results of an extended scaling test of quenched Wilson twisted mass QCD. We fix the twist angle by using two definitions of the critical mass, the first obtained by requiring the vanishing of the pseudoscalar meson mass m_PS for standard ...

Effective masses of diquarks [PDF]
, 2002 We study meson and diquark bound states using the rainbow-ladder truncation of QCD's Dyson-Schwinger equations. The infrared strength of the rainbow-ladder kernel is described by two parameters.

Millimeter‐Wave WISP Search with Coherent Light‐Shining‐Through‐a‐Wall Toward the STAX Project
Annalen der Physik, Volume 536, Issue 1, January 2024.This research article shows potential of millimeter waves for searching dark photons, one of the candidates of dark matter. By sharing a common reference signal, an excellent temporal coherency is achieved between production and detection of dark photons.
