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

Note on the electromagnetic radius of proton

Autor: Ridwan, M., Mart, T.

Publikováno v: Modern Physics Letters A 38 (2023) 2350157

We have analyzed the proton form factor data by using a number of phenomenological parameterizations (models) and extracting the proton electric and magnetic radii. To this end we performed a global fit to all available form factor data, with the vir

Role of the high-spin nucleon and delta resonances in the $K\Lambda$ and $K\Sigma$ photoproduction off the nucleon

Autor: Luthfiyah, N. H., Mart, T.

Publikováno v: Phys. Rev. D 104, 076022 (2021)

We have investigated the effect of nucleon and delta resonances with spins 11/2, 13/2, and 15/2 in the kaon photoproduction process $\gamma + N \to K + Y$ by using two covariant isobar models. The formalism for high-spin propagators and interaction L

Extracting the pole and Breit-Wigner properties of nucleon and $\Delta$ resonances from the $\gamma N\to K\Sigma$ photoproduction

Publikováno v: Phys. Rev. D 104, 056015 (2021)

We have developed a covariant isobar model to phenomenologically explain the four possible isospin channels of $K\Sigma$ photoproduction. To obtain a consistent reaction amplitude, which is free from the lower-spin background problem, we used the con

Role of Resonances in the Electromagnetic Production of Kaon Near Threshold

Autor: Mart T.

Publikováno v: EPJ Web of Conferences, Vol 20, p 02007 (2012)

Kaon photo- and electroproduction processes near their production thresholds are investigated by using an effective Lagrangian method. It is found that the nucleon and hyperon resonances play a considerably important role in this kinematics. It is al
