Vector meson photoproduction studied in its radiative decay channel
, 2005 We provide an analysis of vector meson photoproduction in the channel of the vector meson decaying into a pseudoscalar meson plus a photon, i.e. $V\to P\gamma$.

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

The fate of $$\mathbf{V}_\mathbf{1}$$ V 1 vector leptoquarks: the impact of future flavour data
European Physical Journal C: Particles and Fields, 2021 Motivated by the recent experimental progress on the B-meson decay anomalies (in particular the angular observables in $$B\rightarrow K^*\mu \mu $$ B → K ∗ μ μ ), we rely on a simplified-model approach to study the prospects of vector leptoquarks in what

QCD description of backward vector meson hard electroproduction
, 2015 We consider backward vector meson exclusive electroproduction off nucleons in the framework of collinear QCD factorization. Nucleon to vector meson transition distribution amplitudes arise as building blocks for the corresponding factorized amplitudes ...

Hidden gauge formalism for the radiative decays of axial-vector mesons [PDF]
, 2008 The radiative decay of the axial-vector resonances into a pseudoscalar meson and a photon is studied using the vector meson Lagrangian obtained from the hidden gauge symmetry (HGS) formalism.

Magnetic structure of vector mesons in lattice QCD
EPJ Web of Conferences, 2018 We have explored the response of the charged vector mesons on the external magnetic field. The g-factor of the charged vector ρ and K* mesons has been found.

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