In 2018, the E12-17-003 experiment was conducted at the Thomas Jefferson National Accelerator Facility (JLab) to explore the possible existence of an nnLambda state in the reconstructed missing mass distribution from a tritium gas target [K. N. Suzuk

Fermi motion effects in electroproduction of hypernuclei

Autor: Bydžovský, P., Denisova, D., Skoupil, D., Veselý, P.

Publikováno v: Phys. Rev. C 106, 044609 (2022)

In a previous analysis of electroproduction of hypernuclei the cross sections were calculated in distorted-wave impulse approximation where the momentum of the initial proton in the nucleus was set to zero (the frozen-proton approximation). In this p

Model selection for $K^+\Sigma^-$ photoproduction within isobar model

Autor: Bydžovský, Petr, Cieplý, Aleš, Petrellis, Dimitrios, Skoupil, Dalibor, Zachariou, Nicholas

We utilise an isobar model to investigate the $K^+ \Sigma^-$ photoproduction off a neutron in the resonance region. Except for the Born terms, we include high-spin (spin-3/2 and spin-5/2) nucleon resonances in the consistent formalism together with a

Photoproduction of $K^{+}\Lambda$ with a Regge-plus-resonance model

Autor: Bydžovský, Petr, Skoupil, Dalibor

Publikováno v: Phys. Rev. C 100, 035202 (2019)

Making use of the hybrid Regge-plus-resonance model, we investigate the process of kaon photoproduction off the proton target. We present a new model whose free parameters were adjusted to data in and above the resonance region and which provides an
