Background: In $\pi^+n$ and $\pi^-p$ electroproduction, conventional models cannot satisfactory explain the data above the resonance region, in particular the transverse cross section. Although no high-energy L-T-separated cross-section…

We present the results of a five-dimensional resonant amplitude analysis of the $\Lambda_c^+{\to}pK^{-}\pi^{+}$ system based on $946\pm 38$ reconstructed decays. These data were produced in 500 GeV/$c$ $\pi^-$-N interactions by Fermilab…
