The $ψ$ (2S) state as a subthreshold pole in electron positron annihilation into $D D ˉ$ final states

Peter Lichard

By performing a fit to the merged BES 2008 and BESIII 2024 $e^{+} e^{-} \to D D ˉ$ cross-section data, we find that the $ψ (2 S)$ subthreshold pole influences this process marked…

Lagrangian-based model of the $e^{+} e^{-} \to V V ˉ$ process applied to the $e^{+} e^{-} \to D^{+} D^{-}$ data

Peter Lichard

Using the quantum field theory, we derive a Breit-Wigner-type formula for the $e^{+} e^{-}$ annihilation into a vector meson and its antiparticle, and relate the formula parameters to…

Searches for hidden sectors using $K^{+} \to π^{+} X$ decays

NA62 Collaboration

Results from the study of the rare decays $K^{+} \to π^{+} ν ν ˉ$ , $K^{+} \to π^{+} μ^{+} μ^{-}$ and $K^{+} \to π^{+} γ γ$ at the NA62 experiment at CERN are interpreted in terms…

Search for heavy neutral leptons in $π^{+}$ decays to positrons

NA62 Collaboration

A search for heavy neutral lepton ( $N$ ) production in $π^{+} \to e^{+} N$ in-flight decays using data collected by the NA62 experiment at CERN in 2017-2024 is reported. Upper limits for…

A subthreshold pole in electron-positron annihilation into the $D_{s}^{+} D_{s}^{-}$ final state

Peter Lichard, Josef Juráň

Using precise data from the BESIII collaboration, we obtained compelling evidence of a subthreshold pole in the $e^{+} e^{-} \to D_{s}^{+} D_{s}^{-}$ process with mass of (3896$^{+13}_{…

Subthreshold poles in electron-positron annihilation. D\bar{D} final states

Peter Lichard

We show that the $ψ (2 S)$ subthreshold pole influences the cross section of the electron-positron annihilation into the $D^{+} D^{-}$ and $\mathrm D^0\bar\mathrm…
