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

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. $V\to P\gamma$.

Medium effect on photon production in ultrarelativistic nuclear collisions [PDF]

, 1998
The effect of in-medium vector and axial-vector meson masses on photon production is studied. We assume that the effective mass of a vector meson in hot nuclear matter decreases according to a universal scaling law, while that of an axial-vector meson is

Exclusive production in CMS

EPJ Web of Conferences, 2014
We discuss the CMS capabilities of measuring vector mesons in pp and heavyion collisions based on the recent results of the exclusive dilepton and diboson production. Studies evaluating the detection of exclusive J/ψ and ϒ vector meson photoproduction in

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.

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

Physics 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.

Dimension Six Corrections to the Vector Sector of AdS/QCD Model [PDF]

, 2008
We study the effects of dimension six terms on the predictions of the holographic model for the vector meson form factors and determine the corrections to the electric radius, the magnetic and the quadrupole moments of the rho-meson.

η′ → π0γγ and ��′ → ηγγ: a primer analysis

EPJ Web of Conferences, 2012
The electromagnetic rare decays η′ → π0γγ and η′ → π0γγ are analysed for the first time and their predicted branching ratios given. The vector meson exchange dominant contribution is treated using Vector Meson Dominance and the scalar component is ...

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.
