“…In Refs. [25,26], 2 H(γ, K)Y N is investigated in the non-relativistic plane-wave impulse approximation (NRPWIA) with various isobar models, demonstrating the importance of a reliable elementary-production operator. Gasparyan et al studied the possibility of extracting the low-energy Λn scattering parameters [27].…”

We present a Regge-inspired effective-Lagrangian framework for kaon photoproduction from the deuteron. Quasi-free kaon production is investigated using the Regge-plus-resonance (RPR) elementary operator within the relativistic planewave impulse approximation. The RPR model was developed to describe photoinduced and electroinduced charged-kaon production off protons. We show how this elementary operator can be transformed in order to account for the production of neutral kaons from both protons and neutrons. The model results for kaon photoproduction from the deuteron compare favourably to the 2 H(γ, K)Y N data published to date.

“…The first theoretical studies with deuteron targets, which focused on the role of final-state interactions, date back to the 1960s [1]. Most of the subsequent theoretical work has also focused on the photoproduction reaction, either in connection with model dependence and final-state interactions [2][3][4][5][6], or in connection with a neutron target [7,8]. Some of the more recent work has incorporated rescattering contributions in the photoproduction amplitude [9,10] or employed a Reggeinspired framework to study photoproduction [11].…”

A formalism is presented for the investigation of the reaction ed → e K + n in the relativistic impulse approximation. The formalism is based on a tree-level, effective Lagrangian model for the underlying virtual photoproduction reaction amplitude which incorporates a variety of baryon resonances with spins up to 5 2 and the two kaon resonances, K (892) and K1(1270). The parameters of the model were fit to a large pool of proton photoproduction data from the CLAS, GRAAL, SAPHIR, and LEPS Collaborations and to CLAS data for the virtual photoproduction structure functions σ U , σ T , σ L , σ T T , σ LT , and σ LT . The final-state n interaction is incorporated in the model by means of a three-dimensional overlap integral based on a simple phenomenological n potential. Results are presented for both the differential cross section, dσ/d K , and the double differential cross section, dσ/d K dE K , for the virtual photoproduction of positive kaons and 's from the deuteron.

We present the investigation of the neutrino-induced strangeness associated production on nuclei in the relativistic plane wave impulse approximation (RPWIA) framework at the intermediate neutrino energies. In this study, the elementary hadronic weak amplitudes are embedded inside the nuclear medium for the description of the exclusive channels of neutrino-nucleus interactions. These amplitudes are extracted using a modeldependent evaluation of the hadronic vertex using the Born term approximation in which the application of the Cabibbo V-A theory and SU(3) symmetry are assumed to be valid. The nuclear effects are included via the bound state wavefunctions of the nucleon obtained from the relativistic mean field (RMF) models. Two kinematics settings are used to examine various distributions of the differential cross section in the rest frame of the target nuclei. The numerical results are obtained for the neutrino-induced chargedcurrent (CC) K + Λ-production on bound neutrons in 1s 1/2 and 1p 3/2 orbitals of 12 C.The angular distributions are forward peaked under both kinematic settings, whereas under the quasifree setting the cross sections tend mimic the missing momentum distribution of the bound nucleon inside the nucleus.
