The contribution of axial-vector mesons to hyperfine structure of muonic hydrogen

open access: yesPhysics Letters B, 2018
The contribution from the axial-vector meson exchange to the potential of the muon–proton interaction in muonic hydrogen induced by anomalous axial-vector meson coupling to two photon state is calculated.

B to light meson transition form factors calculated in perturbative QCD approach [PDF]

open access: yes, 2002
We calculate the $B\to P$, $B\to V$ (P: light pseudoscalar meson, V light vector meson) form factors in the large-recoil limit in perturbative QCD approach, including both the vector (axial vector) and tensor operators.

Next-to-leading order corrections to deeply virtual production of pseudoscalar mesons

open access: yesPhysics 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 ...

Configurational information measure of mesonic states in 4-flavor AdS/QCD

open access: yesPhysics Letters B, 2023
Strange axial-vector kaons, K1, and f1 meson resonances are investigated in the 4-flavor AdS/QCD model. Their underlying differential configurational entropy is computed and the mass spectra of higher-excited resonances, in both these mesonic families ...

Central production of mesons: Exotic states versus Pomeron structure [PDF]

open access: yes, 1999
We demonstrate that the azimuthal dependence of central meson production in hadronic collisions, when suitably binned, provides unambiguous tests of whether the Pomeron couples like a conserved vector-current to protons.

Compressibility Function and Speed of Sound in the Non‐Commutative Quantum Hadrodynamics Type‐I Model for Neutron Stars

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT We investigate the effects of a minimal measurable length on neutron stars, within the quantum hadrodynamics (QHD‐I) model modified by the Generalized Uncertainty Principle (GUP). Working in a deformed Poisson algebra framework, we incorporate GUP effects via a time‐invariant transformation of the phase space volume, effectively reducing the ...

Transversity in exclusive vector-meson leptoproduction [PDF]

open access: yes, 2013
The role of transversity or helicity-flip generalized parton distributions (GPDs) in leptoproduction of vector mesons is investigated within the framework of the handbag approach.

Vector Meson Production at HERA [PDF]

open access: yes, 1997
We show that the lowest-order QCD calculation in a simple model of elastic vector-meson production does reproduce correctly the ratios of cross sections for rho, phi and J/psi, both in photoproduction and in high-Q2 quasi-elastic scattering.

Remote sensing of soil organic carbon in varied tillage‐crop systems

open access: yesJournal of Environmental Quality, EarlyView.
Abstract The use of remote sensing (RS) to estimate soil organic carbon (SOC) in cropland has become increasingly important to producers, researchers, and policy makers to assess soil and plant health across spatially variable landscapes. Yet, RS estimation of cropland SOC is challenging, particularly when mixed crop residues and soils are present. Our

Vector mesons on the light front

open access: yesPhysics Letters B, 2004
We apply the light-front quantization to the Nambu--Jona-Lasinio model with the vector interaction, and compute vector meson's mass and light-cone wavefunction in the large N limit. Following the same procedure as in the previous analyses for scalar and pseudo-scalar mesons, we derive the bound-state equations of a q-qbar system in the vector channel ...
