Electron-nucleus scalar-pseudoscalar interaction in PbF: Z-vector study in the relativistic coupled-cluster framework

open access: yes, 2017
The scalar-pseudoscalar interaction constant of PbF in its ground state electronic configuration is calculated using the Z-vector method in the relativistic coupled-cluster framework.

Exploring Dark Photon Production and Kinetic Mixing Constraints in Heavy‐Ion Collisions

open access: yesAstronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.
ABSTRACT Vector U‐bosons, often referred to as “dark photons,” are potential candidates for mediating dark matter interactions. In this study, we outline a procedure to derive theoretical constraints on the upper bound of the kinetic mixing parameter ϵ2MU$$ {\upvarepsilon}^2\left({M}_U\right) $$ using dilepton data from heavy‐ion from SIS to RHIC ...

Two-Point Correlators of Fermionic Currents in External Magnetic Field

open access: yesEPJ Web of Conferences, 2017
We study the two-point correlation functions under an influence of the constant homogeneous magnetic field. In addition to the correlators of scalar, pseudoscalar, vector and axial-vector fermionic currents, we calculate the non-diagonal one including ...

Search for an exotic decay of the Higgs boson to a pair of light pseudoscalars in the final state with two b quarks and two τ leptons in proton–proton collisions at s=13TeV

open access: yesPhysics Letters B, 2018
A search for an exotic decay of the Higgs boson to a pair of light pseudoscalar bosons is performed for the first time in the final state with two b quarks and two τ leptons. The search is motivated in the context of models of physics beyond the standard

Dalitz Analysis of B->K+pi+pi- and B->K+K+pi-

open access: yes, 2004
We report results of the Dalitz analysis of the three-body charmless B->K+pi+pi- and B->K+K+K- decays based on a 140fb^{-1} data sample collected with the Belle detector.

Nonlinear Vortex Dichroism in Chiral Molecules

open access: yesAdvanced Optical Materials, Volume 13, Issue 3, January 24, 2025.
Chiral molecules are shown to absorb two photons from a linearly polarized Laguerre–Gaussian vortex beams at different rates depending on the sign and magnitude of orbital angular momentum: nonlinear vortex dichroism. This new form of nonlinear optical activity is shown to have many remarkable properties, including novel access to structural ...

Relativistic corrections to the pair Bc-meson production in e+e− annihilation

open access: yesNuclear 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 ...

Bounds on very weakly interacting ultra light scalar and pseudoscalar dark matter from quantum gravity

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
In this paper we consider very weakly interacting and ultra light scalar and pseudoscalar dark matter candidates. We show that quantum gravity has important implications for such models and that the masses of the singlet scalar and pseudoscalar fields ...

Study of Semileptonic B⟶DPℓ+νℓ Decays Based on the SU(3) Flavor Symmetry

open access: yesAdvances 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.
