Generalized Vector Dominance Model up to 2 GeV

N. N. Achasov, A. V. Kiselev, A. A. Kozhevnikov

The processes $e^{+} e^{-} \to π^{+} π^{-}, ω π^{0}, η π^{+} π^{-}, K^{+} K^{-}, π^{+} π^{-} π^{0}$ are described simultaneously in the frame of the Generalized Vector Dominance Model (GVDM) allowing model error.…

Shape and dynamics of nonrelativistic vortex strings in parity-breaking media

A. A. Kozhevnikov

The shape and dynamics of the nonrelativistic gauge vortex string in the parity-broken media is considered, upon reducing the problem to finding the extremum of the Abelian Higgs m…

The decay $J / ψ \to γ ϕϕ$ : spin dependence of amplitude and angular distributions of photons with linear polarizations

A. A. Kozhevnikov

Based on the effective invariant amplitudes of the transitions $J / ψ \to γ X (J^{P})$ and $X (J^{P}) \to ϕϕ$ , the spin dependence of the $J / ψ \to γ X (J^{P}) \to γ ϕϕ$ decay amplitude is obtained in th…

$ϕϕ$ and $J / ψ ϕ$ mass spectra in decay $B_{s}^{0} \to J / ψ ϕϕ$

A. A. Kozhevnikov

The mass spectra of the $ϕϕ$ and $J / ψ ϕ$ states in the decay $B_{s}^{0} \to J / ψ ϕϕ$ recently observed by LHCb are calculated in the model which takes into account the $J^{P} = 0^{+}, 0^{-}, 2^{+}$ in…
