Impact of Vector Meson Polarization on Its Interaction with Matter / S.R.Gevorkyan, A.V.Guskov // The European Physical Journal C [Electronic resource]. – 2024. – Vol. 84, No. 1. – P. 7. – URL: https://doi.org/10.1140/epjc/s10052-023-12369-y. – Bibliogr.: 35.

The production of unstable particles on different nuclei provides the possibility to determine the total cross section of the interaction of vector mesons V = ρ, ω, ϕ, K&sup(* 0)(892), J/ψ etc. with nucleons. This interaction is defined by a set of amplitudes that correspond to the transverse (helicity λ = ±1) or longitudinal (λ = 0) polarization of the vector meson. The total cross section for the interaction of transversely polarized vector mesons with nucleon σ&sub(T) = σ (V&sub(T)N ) has been extracted from the coherent photoproduction of vector mesons off nuclei, while the vector meson production in charge exchange reactions as π&sup(±)(K&sup(±))+ A → V*0(K&sup(* 0) + A′ provides the unique opportunity to obtain the not yet measured total cross section for longitudinally polarized vector meson interacting with nucleon σ&sub(L) = σ (V&sub(L)N ). We shortly discuss the importance of the knowledge of σ&sub(L) and possibility to extract its value from experiments on nuclear target.
