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.

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 ...

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.

Relativistic corrections to the pair Bc-meson production in e+e− annihilation
Nuclear Physics B, 2016 Relativistic corrections to the pair Bc-meson production in e+e−-annihilation are calculated. We investigate a production of pair pseudoscalar, vector and pseudoscalar+vector Bc-mesons in the leading order perturbative quantum chromodynamics and ...

q‐Deformed Glueball Spectrum in AdS/QCD Correspondence
Advances in High Energy Physics, Volume 2024, Issue 1, 2024.This work presents the application of the q‐algebra in the glueball spectrum. This algebra is implemented through Jackson’s derivatives in a Schrödinger‐like equation resulting from the gravity fluctuations around the braneworld scenario in five dimensions.

Exploring solutions to the muon g-2 anomaly in a 3-3-1 model under flavor constraints
European Physical Journal C: Particles and FieldsThe magnetic moment of the muon can receive significant two-loop contributions from a light pseudoscalar. Notably, the spectrum of scalars of 3-3-1 models includes one pseudoscalar.

Next-to-leading order corrections to deeply virtual production of pseudoscalar mesons
Physics Letters B, 2017 We complete the perturbative next-to-leading order corrections to the hard scattering amplitudes of deeply virtual meson leptoproduction processes at leading twist-two level by presenting the results for the production of flavor singlet pseudoscalar ...
