Non-universality of color transparency onset in pion and kaon electroproduction

Byung-Geel Yu, Tae Keun Choi, Kook-Jin Kong

A combined analysis of the Jefferson Lab data on nuclear transparency in $A (e, e^{'} π^{+})$ and $A (e, e^{'} K^{+})$ shows that the onset of color transparency (CT) is not universal across meson…

Effective Color Dipole Approach to Color Transparency in $I ¨ ^{0}$ Electroproduction

Tae Keun Choi, Kook-Jin Kong, Byung-Geel Yu

We investigate nuclear transparency in exclusive $I ¨ ^{0}$ electroproduction on $^{12}$ C and $^{56}$ Fe nuclei within a multi-channel final-state interaction (FSI) framework that expli…

Naive parton picture for kaon color transparency in $A (e, e^{'} K^{+})$

Kook-Jin Kong, Tae Keun Choi, Byung-Geel Yu

Nuclear transparency in the electronuclear reaction $A (e, e^{'} K^{+})$ is investigated in parallel with our previous study of pion transparency in Phys.\ Rev.\ C {\bf 111}, 064608 (2025)…

Nuclear transparency and shadowing of the two-step process in the $A (e, e^{'} I ¨ ^{+})$ reaction

Tae Keun Choi, Kook-Jin Kong, Byung-Geel Yu

We investigate nuclear transparency induced by pion electroproduction on nuclei, $A (e, e^{'} I ¨ ^{+})$ , with our interest in the role of the two-step process in the Glauber multiple scatte…

Revisiting $K N$ elastic and charge exchange reactions in search of the pentaquark $I^^{+}$ baryon

Byung-Geel Yu, Kook-Jin Kong, Tae Keun Choi

In the search for the pentaquark $I^^{+}$ baryon, the world data on $K^{+} n \to K^{+} n$ and $K^{+} n \to K^{0} p$ reactions on the deuteron target and $K^{0} p \to K^{+} n$ and $K^0_L\,p\to K^0_S\,…

Partial wave analysis of $K^{+} N$ scattering and the possibility of pentaquark $I^^{+} (1540)$

Kook-Jin Kong, Byung-Geel Yu

Elastic $K^{+} n \to K^{+} n$ and charge exchange $K^{+} n \to K^{0} p$ reactions at low momenta are investigated using the partial wave analysis. Isospin relation gives constrains for the par…
